The ST (i.e., GEMDOS) uses the MS-DOS (3.X) disk and directory structure with
a couple of "minor" quirks: (these are the ones I know about; there may
be others).
a. The media type is only put into the BPB. It is not put into the
FAT. Thus an MS-DOS disk driver that only looks at the FAT to get
the media type will not be able to read an ST disk. In the other
direction, the ST will only be able to read the disk if the BPB
was fully built (i.e., MS-DOS 2.X and greater).
b. The ARCHIVE bit in the file attributes seems to have exactly the
opposite meaning for the ST as for MS-DOS.
