The floppy has about 7-8 files, three of them are created under dos Yesterday, and two are not recognized by FreeBSD MSDOS FS system. When putting the floppy in a Win2K machine, there is no disk format involved. Two un-recgnized files are copied to hard drive, and they are deleted from floppy (mark as erased). Then the two copies were copied back onto floppy, so the FAT table should be kept the same as before. Only the table entries are changed becasue the original entries are marked erased not freed. Thus, there is no file system change. If the FAT16 file system format is not supported, then we may not see other files either, yes/no? -Jin
