"Q: Is it possible to convert a FAT32 Hard Drive to NTFS without losing all data on the drive? I like to change from FAT32 to NTFS, my operating system is Windows XP PRO, how can I do that? Without the lost of my programs?
A: Standard Windows utility that is called CONVERT serves this purpose
Just go to the Command Prompt and execute the command:
C:\> CONVERT C: /fs:ntfs
Where C: is a name of the drive you want to convert.
After machine re-boot conversion process will start and you'll have your FAT32 converted to NTFS without of data loss."
