>At this point, it's too late without a reformat and restore of the partition pre-conversion from backup - he went to NTFS, so there's no more Win98, and no tool to go back safely from Win2K-flavored NTFS to FAT32 without reformatting, not even PM 4.0, and the Win98 registry is a thing from long ago, in a galaxy far, far away...

Good catch. PM 4.0 can only convert:

FAT to FAT32
FAT to HPFS
FAT to NTFS
FAT32 to FAT
