One of the many problems with FAT32 was that files on the drive can
be deleted if power is lost. This is why FAT was obsoleted by HPFS
which in turn was obsoleted by NTFS.
Power loss should not cause data loss which is why we stopped using
FAT even before Windows 95 was released.
Program to convert to NTFS is called convert. But for details, use
Windows HELP command.
