Subject: Re: DSDD can it read SSSD disks

Greg:

Mine can -- donno if that's a function of my wonderful drives (Morrow Decision
I with 8"DSD - I think a Tandon, but forget the model #), or a function of
the Morrow CBIOS that has all the different density formats built in.
Not quite sure how the CBIOS decides what it's reading, but I cheerfully
read and write to  IBM SSSD and SSDD disks I've formatted on my own system,
AND other disks formatted and written to by some sort of 8" drive in
a Santa Clara 10Meg hard disk.  Now the Santa Clara (with their CP/M for
a 56K Apple) won't read mine, no way, not even in SSSD (something funny
about my sectors, I think - I can only go down to 256-byte sectors with
my disk formatter), but I have no trouble reading it.  If I format the
disks on the Santa Clara, I can fill the disk on my drive and the Santa
Clara can read it just fine.

Hope that's an answer.  PS:  I got some Cromemco 5 1/4 disks in from
Langley AFB (I think Cromemco), supposedly SSSD soft sector, but be
damned if my CP/M Apple can read them!  Donno why - I don't like the
Apple so very much, and my disassembly of Santa Clara's CP/M and the
original Microsoft 48K CP/M is not yet complete, so I don't have a
clear picture of the disk drivers yet.
