Does anybody know anything about the disk structures of MSDOS disks?
I am writing an AutoDiskChange type utility for SCSI floppies and I
need to be able to recognize MSDOS disks.
Determining AmigaDOS disks is no problem. Block zero is full of:
(Addr) (Hex) (Ascii)
00366624 444F5301 444F5301 444F5301 444F5301 DOS.DOS.DOS.DOS.
So far, the MSDOS disks I have looked at all start out:
0038CFAC EB349043 444D2020 332E3200 02020100 .4.CDM 3.2.....
Is this a fluke?
Anybody got a pointer to a succinct description of MSDOS file formats?

They tend to be of that form, the CDM could be IBM or something else, though The 3.2 is for MS-DOS 3.2, the version of msdos used to format it. The info I have on the MSDOS formats is from the MESSYDOS device/filesystem drivers. The man files for these have some info on it, look at the source too, quite interesting. Find it at ab20 I think, as well as other places. > -het > > "People in North America are so affluent and so unhappy, > it seems all out of whack." -Heather Lockely [African volunteer teacher] Because they, like most of us (me too, though I am aware of it to a degree) haven't got it thru their thick skulls that affluence/possessions does not equal happiness/security and so lust after more to try to satisfy the security urge.
