With Windows 7 or Windows 8 for that matter, a FAT32 partition can cause issues down the road due to the various limitations of the FAT32 file system. For example, let’s say you want to create a Windows System Image, if you try to save the image on a drive which is formatted with a FAT32 file system the process will fail because FAT32 cannot support files larger than 4GB. That’s a problem being that any modern OS today takes up at lest 40-100GB of storage space.
The solution? Follow my quick How-To below to convert your FAT32 File System to NTFS.
Because it’s possible to experience data corruption and loss when converting a drive from FAT32 to NTFS, I recommend that you either backup the drive before hand OR, copy the data off the drive and perform a standard format selecting NTFS as your file system. On the plus side, there are many advantages of going to NTFS above and beyond the 4GB file size limit such as – auto recovery of disk errors, larger drive size support and security.
Before starting the process, ensure you have a few Gigs of free space as the conversion does require some space.
Open a command prompt window by typing Command prompt in the Windows search box.
Type in convert drive_letter: /fs:ntfs . You will, of course, replace drive letter with the letter of the drive you’re converting (c, d or whatever that might be). Press Enter to being the process.
The file system conversion process should not take very long and the on-screen details are fairly intuitive.
Once completed, your old FAT32 drive will be converted to NTFS. Close the Command Prompt window and you’re all done.
