You and my friend both are experiencing problems with ICD formatted 
partition.

The DOCs with PC_Ditto (II) describe the problem and a fix.

The problem:

MS-dos and PC_ditto are very fussy about what the see in the boot block
of the C: (and other) drives.  (THIS IS NOT SECTOR 0).  Some formatters
and Partitioner do not put the right stuff their.  HDX from Atari is
screws this stuff up.  This was the root of the floppy incompatibility
problems; but few people exchange Hard disks witha PC.  It looks like
ICD now does not put the right magic there.

If the ICD editer is a smart as Supras, display the boot for C:
and make sure that there are 2 not 20 fats, and the media bytes is f8.

Avant-Garde now supplies a fixup program with PC-ditto II, but its
needed for I also.
