Hi,
In the discussion on HP LIF disks and bad sectors, I was pointed towards the 9895A service
manual and its?description?of initializing floppies, marking 'bad tracks', and bad
sectors. I have the 82901M 5.25" and 9121 3.5" drives, so have had a look in
their service manuals for similar descriptions, in case there were any differences or
further nuggets of information. The 82901 manual said very little on the topic, but the
manual for the 9121 (covering several 3.5" drives) shows in the contents that
Appendix A describes the command set. I had a look at the scanned version:

and copied here:

but Appendix A is missing, does anyone have a link or a scanned copy please?
Regards,
John
