I needed to convert a FAT32 drive to NTFS today and as it was 500GB I wasn’t sure how easy it might be. I contemplated backing it all up then formatting it, but then I found out you can do it on a live drive.
Backups are always recommended – I made an educated decision not to on this occasion but if it had of gone wrong I would have lost over 400GB of files.
Below is the output from command prompt. In Windows 7 I searched for CMD and ran it as an admin to do the below. E was the drive I was working on and the command is;
convert e: /fs:ntfs
