How to Recover Data from a Hard Drive that Won’t Boot

Windows 8.1 and Windows 10 has several built-in utilities that allow you to recover data. But what if your drive won’t boot? Here’s how to get it.

At some point or another, technology can and will fail us. For this, we should regularly implement backup strategies to protect our data. We store a lot of important information on our computers and devices; documents, photos, and videos, so losing them can be a terrible regret. Thankfully, Windows includes a host of solutions that makes backing up your information simple. Whether it’s Backup and Restore, System Imaging, File History, or OneDrive. In this article, we discuss a situation that can be a tough one to overcome; what happens if your computer is not booting?

Recover Data Non-booting Hard Drive

For me, this was a reality I recently experienced. I had already backed up recently, but I also created new content that I didn’t want to lose. After exhausting many repair options, I could not get Windows to boot successfully. I even attempted the Refresh options. Of course, I could try doing a custom install and salvage my data from Windows.old. Unfortunately, I was in a bind, with no working optical drive or a USB stick I could use. So I thought of the next option; putting the hard disk in an external hard disk enclosure, connecting it to a working computer, and copying over my data, so this is what I ended up doing.

Obtain an External Hard Disk Enclosure

This is the first thing you will need to have. They are quite cheap, and you can use them also with an existing hard disk as an external storage device. An enclosure is basically a housing that protects the drive and allows you to connect it to a USB, FireWire, or eSATA port. You can pick up an enclosure for between $20 to $50 on B&H or Amazon. They are available in 3.5-inch (standard desktop) or 2.5-inch (notebook) sizes. Make sure you pick the proper internal interface—IDE/ATA or SATA, based on the type of drive you are using.


Uninstall Non-booting Hard Drive 

You will need to remove the hard disk from the system unit to install it in the external enclosure. The process will vary depending on the build, model, and form factor. Consult the manufacturer’s documentation that came with your computer, or review the manufacturer’s website. Some are easy and require pressing a latch mechanism to release the hard disk from its drive bay.

Other configurations might require removing a mounting mechanism, especially if it is a 2.5-inch drive. Be prepared to have essential tools such as a Torx 5 point screwdriver and or flat head screwdriver. If you plan to build your own computers or do these types of repairs often, get yourself a decent set of tools in a computer repair kit.


This particular configuration uses a 2.5-inch drive on a 3.5-inch mount. You will also notice the green latch mechanism for releasing the drive from its bay.

Install Hard Drive in External Enclosure

Installing in the enclosure should be easy. Depending on the enclosure you buy, you might need to make some manual adjustments. Some might require you to insert the drive, and that’s it. My external enclosure requires me to connect the SATA cables to the drive manually in the following picture. A straightforward thing to do. As you can see in the above picture, this external enclosure also supports PATA drives too. Once you have installed the drive and ensured it’d connected securely, I can insert it into the protective casing.

Connect USB and Power Cables

The next step is to connect the drive to your computer. There is nothing to it since this experience will be just like connecting a regular external hard drive. Once the drive is turned on, Windows will automatically detect the drive and install it. You’ll either be prompted to browse for it, or you can access it from File Explorer.

Recovering the Data

Now we would expect to browse the hard drive and copy over our data. Because the installation on the drive is still protecting the folders with your data, you’ll get an error message if you try to open and browse the folder. If you cannot open this folder after clicking Continue, review our article for instructions about taking ownership of a folder.

No Permission

Now you can browse the User folder and proceed to copy over your data. Here I am Preparing to copy over data from the external hard drive to my local hard drive.

Copy Files

When you are sure you have recovered your data from the hard drive, you can format and repartition the drive if you wish. Remember to browse the common locations where data is stored, such as your User folder C:Users and C:UsersPublic. Also, if you have unstructured information such as Sticky Notes, you can find those in C:UsersYourAccountNameAppDataRoamingMicrosoftSticky Notes, copy the file StickyNotes.snt into its respective directory. This drive, in particular, had experienced one too many power outages resulting in the corrupt installation of Windows.

    A few points from my fun with this situation:
    1 – is the non-boot because the drive is dead, or the PC won’t access the drive – BIOS changed to not use the drive’s connection, or maybe the partition has had it’s ‘Active’ status removed, or the partition table is dead.

    Partition table – well do you have an appropriate booting recovery CD (USB stick)
    Active – easy to fix – any partition management facility
    BIOS – even easier – and part of the basic test – can you get the PC to startup, and get at the BIOS to check it, and change it as needed – a dead battery may cause the BIOS to just go back to the Defaults every time you power the system off
    Drive dead – or the interface dead – Well it’s open the casing time – but first listen when you power up the PC – you should hear the drive spin p and click, or maybe hear a few beeps – or maybe get a message on the screen about hard drive or boot problems.

    OK – so BIOS is OK – points to the hard drive, and time updates appropriately but
    you cannot get the system to start from the hard drive.
    Can you get it to start from a recovery CD – and if so, does it indicate it can see the partition(s) on the hard drive – OK – the article is no USB stick (and presumably no CD drive).
    But – the question is – before opening the PC, can you access the data on the partition(s)
    If so, then you can probably use the drive in another PC and – relatively) easily recover the data.
    If the drive does not appear to have accessible partitions on it – then that’s a whole new kettle of old fishy bits.. You’ll probably need a ‘Pro’ rather than a Free version of a data recovery facility
    You may be lucky and have, or find one that will re-specify the partition – but DO NOT format any partition on the drive, you should, at this point do the USB case thing –
    Re USB cases – check that the case will ‘manage’ drives of the size you have.
    There are alternatives such as a drop-in box, where the drive just pushes into the hole in the top – but that does leave the drive electronics etc. exposed and more vunerable.

    Also remember Bitlocker – or other drive security facilities will cause you a whole lot of extra pain if you don’t have a key USB device –

    OK – now some laptops have an easily replaces hard drive and on others opening the laptop is frequently a case (ha) of finding where the latches are.
    In my toolkit I’d include some feeler gauges – any car accessories shop, the thin blades can be used to poke in the edges of the case, but just a couple of mm, you want to locate the latches on the case, not the components inside it. – Internet is often useful for technical – workshop documents.
    If it’s a desktop or tower system you may well have 2 interface connection interface ports, and maybe just need a 3.00 adaptor from the older style power supply to the new SATA one.
    However you may need a carrying/fixing bracket for the drive.

    Re new drive – Currently, I’d look at those with just 1 platter, possibly 2TB drives – You may not need the space, but packing density on the platter mean that the tracks coming under the heads at 7200rpm? may give you double the throughput of an older 250GB drive

    My view is that if you have problems with an old drive (over a year old) it’s probably best to get a replacement anyhow. more speed and you should assume there is a problem with the old drive –
    you may not have proof, but there must be some reason for the problem.

    So – now you have a new drive in the system use a windows 10? DVD ? to reinstall an OS – well you do have the licence code from the old system, and qualify for the free update, don’t you.
    Leave enough space unallocated on the new drive for a copy of your old OS partition – or maybe 2 copies – 500GB should be enough for a Win 10 environment.

    There are other ways to install win 10 – without a DVD or USB connection – as in web download but you’ll have to see other articles for them.

    Now – if you can access the data on the drive, make life a bit simpler – create a new id using your ID and password from the original system – that will, hopefully mean that ownership and encryption is dealt with by the OS accessing the data under your ID that matches that on the drive’s files.

    If you can copy all the partitions content, use xxcopy or robocopy, or a partition backup facility as the OS frequently uses the shortname for files that you don’t normally see, and when xcopy, or file explorer- drag.drop is used new shortnames are created, but the old OS won’t know about them.

    So – having copied all the files onto the new drive, maybe it’s time to see again, if you can get that OS to startup in the original system, or as the only drive in the system –
    And if not, maybe do an update install to win 10 over the newly created copy paritition – and tell the install to keep the old OS and data
    That may well get you able to use all the apps and data you were using

    Ah! – and if still using email in POP3 mode from a different device – you did remember to set the facility that the messages will need to be downloaded to your ‘other’ email store.

    If you didn’t manage to recover the system, you may need to set up a new email link- and re-synchronise that new link on your device to match that on your ISP’s server –
    remember you sync to them, not them to your EMPTY setup!

    I got an enclosure for a 640GB SATA drive. The drive is from an HP All-in-One that had Windows7.
    But Windows 8.1 does not recognize the drive. Tried running “chkdsk e: /f” on it.
    Got msg “Chkdsk is not available for RAW drives.”
    Appreciate any help.

      September 11, 2015 at 6:14 am

      Hoping for a more informative and instructive response from the groovypost people, BUT
      it seems – first guess – as if the partition table on the drive has been corrupted, or erased.
      Chkdsk runs on partitions that have been formatted and checks the file and space allocation tables – Note not the files themselves.

      Now – is windows not recognising the drive – as in Storage Management does not see the drive, or is it just that windows 8 does not see any partitions on the drive.

      Not recognising the drive usually means the electronics, or the connection is bad, or if you are lucky – the BIOS has been set to ignore the interface, and just needs a prod to check the connection.

      not recognising the partition means that the partition table has probably been cleared and you’ll be looking for a data recovery program that will re-instate the partition detail –
      If you created a recovery CD/USB stick, that may have the requisite data and program to reset the partition details.
      Other than that, it’s harvesting individual files – as far as a data recovery facility can do – and then checking the recovered files are actually containing the data you expect, and have not been created as the joining of bits of two, or more files.

      Then – there is the consideration – as to why the partition table is damaged/missing – power problems – system powered off while it was writing to the drive, or the drive has just given up with that part of the information on it.

      Yes – I suspect you are in the tuff luck situation where the data is probably not recoverable, but the drive is working well enough to keep you trying.

      So – that will be a new system, or a new drive and make sure you do adequate backups of your data to be able to get it from the backup if the system loses another drive full of information.
      Then again if another drive goes, it should be a reasonable assumption that the drives can be reused – once you get a reliable PC.

      Maybe consult the tech department at your local PC store – just don’t have a high expectation of anyone recovering the data from that drive, however you may be one of those lucky few..

        September 11, 2015 at 12:36 pm

        Thanks, James. Windows 8.1 actually sees 3 partitions on the drive – 2 data and 1 recovery. I’m really not interested in recovering any files, just use the drive as a backup.

        But when I try to reformat the 2 data partitions, I get the message that the drive cannot be reformatted. The drive is a friend’s. One day, his PC could not boot up (beyond the warranty period); the store told him it’d take more to repair than get a new PC, so he got a new one. I’m trying to reuse the drive, but it seems that’s not possible…or not worth the effort for an unsuccessful end.


        • James

          September 11, 2015 at 1:11 pm

          Firstly – I mostly advise those I support to get new systems if their old ones have problems –
          Cost of investigation and repair will usually start at £100 using a super-store technician. and a new system should be expected to have a 3 year warrantee, better screen, comms, external interfaces, battery, and much faster throughput due to more memory, faster CPU and higher packing density on a spinning hard drive, if they don’t get a SSD one.

          Now – to the drive you have –
          That the OS sees 3 partitions means that recovery of the data is much more likely.
          Data indicates it’s use, but not the file management system being used on the partition.

          As you do not want to recover anything from the drive, the best option I can suggest is to ignore that the partitions may not be formatted as NTFS, or a variant of FAT file management facilities that Windows recognises, but may be one of those used by Linux, or other OS’s.

          Just use the Storage management facility and delete the partitions, then create new ones in the free-space.
          A quick format as NTFS should then make them usable under Windows.
          (You could use FAT32, but many multimedia and DVD images are too large for FAT32’s limited file-size).

          You can probably get far more detail using Google search key such as “reusing hard drives under windows ” and add in your windows version at the end.

            Thanks, James. Will take your advice and delete old, then create new, partition(s).

    Hello james, i want to ask you if it is possible to still recover files from a hard drive that was started to format for up to 5%, and then cancelled. thank you

  4. James

    January 9, 2016 at 3:21 pm

    Depends has to be the answer!

    The actuality is likely to be NO – but it does depend on the format option you used, and the file management system used for that partition?

    And – yes this is a longer post than a straight Yes or No, and quite rambling, but there are many considerations for recovering – even something as simple as a lost partition definition table.

    My first consideration would be – reload the partition from your backups!
    but considering you are posting about recovery of the data from the drive I assume that you do not have a readable backup –
    Been there – system failed taking out all drives while the backup drive was being updated.

    So – first consideration

    Are you willing to pay lots more than the cost of a drive to have a professional data recovery organisation recover as much as is possible from that drive !

    Second consideration is it worth the effort to do a sector-mode image of the drive so you can work on the copy to see what can be recovered, with the option of re-doing the copy if your ‘try’ goes wrong.

    Third consideration, ‘Data Recovery’ ill probably want an additional drive as a destination location for whatever can be recovered from the drive

    And – that’s without even considering that you may have encrypted the data on the drive – Bitlocker, or windows folder/file encryption – remembering that windows now uses a dual key for encryption – part being the key you type in, and the other being the systems id – so the data may only be accessible in a decrypted mode on the system that was writing it.

    You did not indicate the format options you specified – or the OS you were using.
    Considering that:
    FAT modes have almost all the file management tables at the start of the drive- so 5% will almost certainly have cleared them,
    NTFS has much of the file and space management in the middle of the space, so 5% may not have reached them.
    Or were you using a different file management system?


    Firstly I presume it was a partition that you were formatting!
    Formatting of the drive (usually referred to as a ‘Low-level’ format) is a fairly thorough way to remove data from a drive – as it actually writes a new ’empty of data’ sector image to every sector of the drive, and may even, – without the appropriate options being selected make the drive unusable within windows and most other OS’s

    And –
    assuming no encryption, and basic windows file management structure formatting.

    If you opted for a full format of a partition that process will write ’empty’ blocks over the sectors that were defined using the low-level format of the drive that was done at the factory.

    If you opted for ‘Quick’ format – that will have ignored the data on the drive and just written a new ’empty’ set of MFT, or FAT and space allocation tables – so the data will still be there, just as blocks that will not be joined up into files

    Now – if you recognised 5%, it is unlikely to have been a quick format.

    If so, and the prior format was a FAT version, then it may be possible to use a DATA RECOVERY program/App to read through the blocks on the drive, and recover individual files from the drive space – a long and slow process that may end up with very few of the files you wanted.

    Now If the file storage system was NTFS – then the start by considering –

    If the file storage system was NTFS, then can the NTFS controls be made re-accessible by redefining the partition definition –
    Well, first see if the OS will recognise the partition as NTFS and let you access many of the files, some of which will not be acceptable to the program associated with the file type – as the file content will be ‘deleted’.
    See if you can have the partition controls area re-written so the MFT (assuming it is not overwritten) can be read – again, some files will have had the content ‘deleted’.
    Either using a partition (well MS and others call them drive) recovery facility – as in the ‘recovery disk you are invited to make under windows.
    If that is not possible, then maybe something like Paragon backup *& recovery, or some other similar drive recovery software will re-create the partition definition controls for you –
    The partition definition table includes details of the file management facility type, version and where the main tables are positioned on the drive, so that may be able to rewrite the table indicating where the MFT etc. are.

    Or – you will be at the scan the drive surface for whatever is possibly a file of the type the scanning software is looking for.

    Additionally under NTFS, small files do not get allocated their own blocks within the general file-space on the drive, but get held in the MFT area – (Theory is – no point in having 200 bytes of controls and 4K of space allocated for a 40 byte file!)

    Does this work for laptop hard drives?

  7. James

    February 1, 2016 at 12:50 pm

    You don’t actually specify what it is that you are asking about ‘Working”

    But the situation is pretty much – a drive is a drive – and if used within the windows environment will have similar setups.

    laptop drives are almost always the smaller physical size – 2½” or maybe smaller while desktop and server drives tend to be the 3½” variant.

    And – you’ll need to be careful about detaching any cables as laptop connections are usually much more fragile and may well have extra securing – as in clips to hold the cable in place on the drive and on the laptop chassis and motherboard/power supply.
    They also tend to be easily damaged by any tools – and fingernails.

    Hi there,

    So I have a Hard disk, that was mounted on my stationary computer, with windows (can´t remember what version).
    I have then sold my computer, and uninstalled the hard disk from the computer.
    It is a Seagate 1 tb, and I have a 3,5″ USB to SATA HDD External Enclosure for it.

    Connected it in my notebook, where it said that I haven’t autorisation for looking in the folders. Did what you stated above in the tutorial.
    I can see my User folder, but there isn´t anything in there (only default user).

    I´ve been told I can use a get data back, is that true?
    Or use a USB 3.0 to SATA/IDE Adapter.

    What is the best suggestion that you can give me?

    Kind regards,

    • James

      September 10, 2016 at 3:00 pm

      From your posting you have not deleted the files or partition, and there is a folder showing – so the files should be there.
      That leads to considering any reason for Widows not showing you what is on the drive.
      Now – you could try installing something like Treesize(free) and then having that show you what is on the PARTITION – including some files and folders in the recycled files folder that the recycle bin may not show.

      However, you should make sure that you are using an admin authorized userid for that – and then, after you have sorted this matter, make sure you go back to using a normal (NOT admin) id for web browsing etc.

      It could simply be that the view settings for Windows File Explorer is not set (Options View) to show you hidden and system files – and using an id that is not an owner, or authorised to access the files and folders created under the earlier OS means it considers it should NOT show your new ID those files belonging to, and restricted to be accessed by that other id.

      Now AFAIK Get back data is for recovering data that has been ‘removed’ from the system, and this is hopefully just windows hiding the data from your new ID – just needing you to get windows to show you the data, and allow you set the OS to allow you access, or to take ownership – hopefully simple using an admin authorised ID.

      • Bettina Jespersen

        Hi again,

        So how do I use an admin authorised userid, cuz when I right click with the mouse, nothing show up.
        And what do you mean to go back to using a normal NOT admin id for web browsing?

        The settings are set up to show all hidden and system files. That was the first ting I did. :)

        This admin/authorised ID, is it the one I made for when I had the HD in the computer?

        Isn’t there a way that you could show with pictures?

        Will try with Treesize.

        Thank you.

          You should be able to see the user accounts on the system using the path selection
          Control Panel
          User Accounts
          Manage Another Account

          Re right-click – right-click on what?

          If you ‘browse’ using an admin authorised account, then any malware you link to will have ADMIN access to your system.
          So it is better to have a userid that does NOT have admin authority and use that for any browsing – and probably most of your normal work.

          Maybe it’s worth asking Andre if he can help –

          If he actually has the time available,
          maybe he can ‘remote-access’ your system and then you’ll be able to actually see what he does to see what there is on the system.

            After some time, I’m back, and still with the same problem.
            I do have admin authorised account, but I can’t go into the files on my external hard-disk, as it says I don’t have access to them.
            I tried doing to take full control, but can’t edit the the protected registry keys.
            Is there some way I can boot from the hard-disk, so it “thinks” it’s in a computer, and then copy the files I want over to another drive?

            Kind regards,

    James I have an Asus X553s and lost my windows password. I have tried all the fixes and 2 paid programs to recover and or reset the password. All have failed.
    So can I remove the 2.5 inch drive and recover data with an enclosure? Or will I still have the same issue of the password etc?

  10. James

    September 18, 2016 at 12:03 pm

    That depends – but first you should indicate to the list what your OS is – type, level and version.
    You may be able to access your system by setting the OS to 1st ignore the password, and then to accept a new password.

    Re the backup – If you do not manage to reacquire access to the system –
    So that will be a new OS – probably almost as cheap to get a new PC

    That is one of the scenarios – considerations that the article is about – restoring the backup to a new system – Forgetting the password for the OS is not something I have included in the possibilities that would need recovering from.

    And – be careful about the help you get – primary consideration from ALL helpers should be that they may well be committing a criminal offence assisting someone to access data from/on secured PC.
    (UK maybe a year in jail and £10,000 cash penalty.)

    So – is your data encrypted using the NTFS (Microsoft) facilities – decryption will need the password.
    Is your drive bitlocked – MS may have the decryption keys, and m,ay be persuaded to pass them to you.

    Is your logon a MS linked one, or not, if it is an MS one, then you may be able to get MS to reset it for you.

    This sort of situation is why I recommend that users have –
    Their own – selected at OS install Admin level ID – with very good password.
    The Admin install id exposed to the login screen and with a good secure password.
    A basic NON-Admin id you use for general work – again – with a good password.
    And passwords should be from a phrase you easily, and frequently remember – N characters being every i’th character from an old address maybe, then use a sequence of characters from that – maybe with an added ending sequence of characters that are used in many passwords.
    You can – with reasonable safety write down n & i – just not the source character string.

    So – what OS?
    What encryption/security?
    – And –
    What backup do you have?

    Re recover data using an enclosure – depends on the encryption and security you have implemented.

    Well your applications will probably need reinstalling on the new OS

Then i removed my hard drive from the laptop, it was Seagate 1tb SSHD. i put the the drive in a cheap brand usb enclosure and tried to connect it the other laptop. Both dead and running laptop had windows 10 installed. So when i connect the hard drive via enclosure the laptop, the file explorer, device manager starts running slow. everything else is running fine. then i thought maybe enclosure fault so i tried a usb adapter and again connected it to the laptop, again same thing happens. So i opened this device manager and checked for any drives problems, i find “WPD system something” showing yellow marks and sometime it names changes to the partition letter but still that yellow mark. I went to a PC technician too, and when he plugged the hard drive to his laptop (windows 7) my drives autoplayed and opened all the partitions, and when we started browsing, it got stuck. since after that same thing happened on the PC technician’s laptop to. Then again i tried on my home laptop, then finally in disk management, it shows all the partitions, when i click on them it says “the request failed due to a fatal device hardware error”. My laptop is 3 years old, is there any way to recover my data from it ? Or format it? Or use the hard drive again? I have no idea what is wrong with it as i am a medical student and i dont really know about this stuff. I have searched online but i dont really know what is wrong with the drive.
    Help will be greatly appreciated,
    Thank you.

      Firstly, I would consider going to a different technician and telling them what you posted –
      I would consider anybody connecting a drive to their live system and letting it ‘Autoplay’ is not thinking about the possibility of malware being on brought in drives –

      To my thinking maybe not a more substantial failure than allowing customers to use their system to browse the internet, but it’s up there.
      I do not even allow Autoplay on my USB backup drives, and they (AFAIK) never leave my premises, or get connected to other PC’s.

      Cheap brand USB enclosure may be limited to 120GB, or even 80GB drives,
      While the SSHD (SATA-II? should be backwards compatible) you should NOT expect the enclosure (or anything – hardware or software) to be forwards compatible.

      Now – back to the SSDH – what hardware and OS version and specification were you running it in/on/with.
      Is it MBR mode or not
      is the PC set to boot using BIOS or UEFI mode.

      Then – your post says the drive in the enclosure appeared to be dead,
      and – your post says the drive in the enclosure appeared to be OK – just slow.
      You also say it changes names of partitions – names or assigned letters? and while running, or different after you restart windows

      NOW – back to the drive – was it in the PC when you got it – and do you know if it needs special device drivers to run under basic windows

      Now – you state disk (storage?) manager shows the partitions –
      what partitions, and what are their descriptions, format etc.

      Re your laptop being 3 years old – are we talking about the laptop or the SSHD
      Laptop – see if you can get to the BIOS – or is it UEFI
      Ideally see if you can boot it from a DVD or USB stick – basicaklly just need to know if – say partition manager or OS install software will start
      If so – maybe install a small (old ) hard drive and see if you can setup and ‘format’ partitions on that – if so, then your next problem will be to install windows – activation would be nice if Microsoft records (know you are the user of) that system.

      Re. recover data from the SSHD – if the drive will respond to read requests – probably, but ..
      Recover only data files and copy them to a separate device –
      You may have to use an ‘admin authorised id – so that will be on a VM – or other ‘sandbox’ facility – a technician should know about, and be setup to do that.
      Ideally the id and password will be the one you had on the failed OS – if not, then
      You may have to ‘take ownership’ of the files under the userid you are using.

      And – when you get back to a working system –
      setup and use a backup process that will allow YOU to recover in the event of a catastrophe –

      Catastrophe –
      PC dies (or gets lost) and you need to get another one
      Drive dies and you need to get another
      Your residence gets burgled and the PC and all backups (receipts etc.) go

      Recovery –
      Windows and the entire set of software and data onto that PC or a new (different & better) replacement PC
      Install new windows and new software purchases – then reinstall your data.

      Note – you will need ‘your data’ to be backed up onto a remote location to deal with the theft catastrophe.

      There are so many possibilities that recovery of a system is getting to be a hands-on job, requiring special recovery environments and maybe several hours of checking –
      and then …
      1TB of 1,000,000MB data transferred through USB-2 – maybe 30MB/sec = 2GB a minute – so that’s maybe 10 hours to copy 1TB – OK USB-3 is faster and usb-3.1 faster still,
      BUT is the drive capable of that rate?

      So – decide how much effort and money you are willing to put into ‘restore’ of what part of your system, then consider how much effort and money is needed to create adequate backups to be able to do that recovery after a catastrophe

      And I say catastrophe – because if it wasn’t one of them you wouldn’t be worrying

        Sorry i dont really know hardware and OS version, or not familiar with these mbr thing. i will like to summarize my problem again. when the laptop failed to boot from its hard drive, i removed it and tried to recover data from an usb enclosure, but once i plugged the drive to another laptop it was getting stuck. so changed from usb enclosure to a usb adapter which is 3.0 then again connected to another laptop still it was getting stuck while it was connected. So i went to the technician so tried different adapter, and my drive was letting me access the partitions and folder’s in it for a while then again it started to get stuck. Basically, when i connect the drive with usb adapter or enclosure, all my partitions are shown on file explorer when i open FE. but its just shown, it doesnt load and starts getting stuck. recently i tried connecting my drive again so that time, i dont know how, it let me access system reserved partition on my drive and all other partitions we showing “fatal device hardware error” and even in disk management all the non accessible partitions were shown as RAW partitions. So 1 time i could access all my partition for few seconds was when the technician tried, next time was this RAW thingy. rest times it just doesnt load up, the laptop starts getting stuck. And sorry it quite hard to explain this stuff to a technician because i live in china right now, and i dont speak proper chinese. :( so i will like to know what could be the wrong with the drive?

          Basically – you seem aware of almost as much as can be determined without actually putting the drive into a system setup to allow the checking of the drives setup and content.
          Showing as ‘RAW’ – tends to indicate the partition descriptor entries are bad.
          Being able to access the stuff on the system reserved partition compounds the impression that the drive content have been corrupted.

          BUT – the problem with a forum is that we cannot examine and test the drive to guess if it is a PC/windows fault – writing bad data to the control areas on the drive, either hardware fault, or a windows fault, or malware in the windows system, or maybe just a powersupply problem at startup or power-down.
          OR – it could be that the drive electronics are failing – maybe it’s got to the point of being very temperature sensitive – that’s usually followed by a complete failure.
          OR it could be that the drive needs special drivers to be loaded in order for it to be used within Windows.

          In short – for it to be diagnosed you need to take it to a technician with an appropriate set of equipment setup to allow the drive to be diagnosed and – hopefully data content recovered.

          Me – I’d seriously consider getting a new PC – that may be cheaper in the long run – better faster system and 3 year warrantee, than paying for a technician’s time , expertise and equipment to determine what needs fixing (maybe not the problem’s cause) and then charge for the fix with a 30 day warrantee – but just on what the technician sold you,

          Note – that is accepting that, while you may be skilled and competent in your own areas, you are not a skilled and experienced IT hardware and PC systems technician and do not have the needed equipment to determine the problem, let alone it’s cause.
          And consider _ got given an I7 system that had stopped booting – drive seemed OK, memory seems OK, so that’s either the motherboard £500, or the CPU £500, or the PSU (£50) needs replacing – I put in a replacement (tested) the PSU and no change – so..
          do I spend £500 hoping I replace the faulty component, or spend £1000 for both (remembering a bad motherboard can wreck a CPU, and a bad CPU can stop a motherboard working) and for the £500 or – maybe £1000, get a non-warranted system of about the same capability as an unused (new but outdated) £600 system?

    Hi, I have a WD400 death hardrive, I am trying to recover the data using an external usb conexion. It spins but it won’t be detected by my computer.

    What can I do?

    Thanks in advance

      HI Tanya,

      Do you have a backup? I ask because sometimes we forget to pull the data from the backup if we have it. I use Crashplan and it’s rock solid. So…. even if you don’t have it for this failure, don’t get bit again by not having a solid cloud backup in the future.

      If the drive isn’t responding even after putting it into an external enclosure, it could be beyond anything you personally can do. If the circuit board fried, there really is very little you can do.

      One thing you can try is an old trick I did a few years ago. I had a Western Digital drive that died while still under warranty. WD shipped me a new drive and thankfully, it was the EXACT same hard drive – 100%. As a last ditch effort…. I took out a few screws from the drives and swapped out the circuit boards. Like I said, they were an exact match. My old drive came online with the new Circuit board and tada – all my data was there. I recovered all my data from the old drive and swapped the circuit board again.

      I was really lucky but, I can testify this DID WORK. It’s worth a shot if you can 1: Find the same drive again or 2: Get a new drive on RMA.

      Let us know how it goes!

    Thanks lol that is sad :( I still had hope lol but that is fine I guess that if its spinning but the heads not responding there is not much you can do. Thanks anyway I will try your suggestions :)

    Hi, I had a slight problem with my Toshiba laptop (Win 10). It was running slower than usual so I downloaded an antivirus program and let it test the system. It suggested running the check in safe mode. The computer shut down and restarted. It asked for my password but doesn’t recognize it. I tried my Microsoft password and the password I’d set for the computer and also the pin that I’d set, none work. I went to the Microsoft site (using my phone) and changed my Microsoft password, still it doesn’t work. It’s 24 hours since I did that and it still doesn’t work.

    I tried accessing my files by running the computer with a CD version of Ubuntu, hoping to transfer my files to a sd card – it won’t let me access the files. I looked online for help on various Linux forums, but none of the suggestions worked.

    I am now thinking of buying a dock to put the hard drive in so that I might transfer files to another PC, but I imagine I may have the same problems due to Win 10 ‘security’.

    Is it likely that I will be able to access my files this way, or would I be wasting money buying the dock (I’m currently out of work and money is very tight)?

    Any help or advice would be gratefully received.

    Thank you.

    I don’t believe what just happened! I just sat down in front of my laptop and thought about what I might have used as a password if I was being asked for one when I didn’t see the point in even having one… I typed in the silly, and totally easily guessable password, and lo and behold, it let me in.

    I am now backing up all my important files, then I will do a full reinstall of Windows.

    So sorry to waste your time with this!

    Kind regards

      No worries Ian. My suggestion – pay a few bucks a month for a quality backup service like Crashplan. Always backed up, get to your files from any machine, secured in the cloud if you lose a drive or your house… (fire/theft/etc..).

      It’s what I use and it saves me often. ;) Founder

    Thank you Steve, that sounds like an excellent idea. I was very lucky this time, but that sort of luck is a fluke and not something that I should rely on.

    Thanks again!

    Andre/or anyone that can help,
    After I had the same situation as described in the article where my hard drive wouldn’t boot at all (and Windows not starting), I have proceeded to do exactly what you have done in the article.
    However, the other working computer wouldn’t detect my hard drive or the enclosure usb neither. Nothing appears in the Computer files to say that something new is connected, or in the Disk Management program.
    Also, when connecting to the computer, the hard drive is running but makes some clicking noises, and the enclosure still shows a green light.
    I’m very confused/distressed, and not sure what to do next…

    If anyone can help please don’t hesitate.

    PS. The Dynamode SATA enclosure did not come with any instructions at all.

    my HDD is dead. But I assume its spining caus a hear a very low sound like it spins.
    I have not erased anything.

    It turns up in disk manager with no drive letter and say NOT initialised. It has zero bytes,

    In Win 10 it says unit working fine.

    Is it hard drive failure or is it PCB or is it firmware.

    What can I do to recover my files.
    Its a Hitachi Deskstar

    Needing help and am not tech savvy.
    I took out my hard drive from my Toshiba satellite laptop of 4yrs after the screen shattered and body casing disintegrated and i inserted it into sata to USB 3.0 cable and all I see are files and when I click on them I see no documents, no music and nothing to download. How can I recover my documents and why is the new laptop not recognizing the hard drive and how can I make it work for me? I have so much to lose. YouTube videos not helping. Can anyone PLEASE HELP?
