A second problem is low-level formatting these hard drives. Some machines 
don't seem to have the software to do it, and just about every controller 
has its own format.

You mentioned the HPIB drive boxes. I use an HP9133 (I forget the suffix 
letter, its a 20Mbyte one in the more modern, smaller, box) on my 
Integral. Althoguh the drive mechanism is a standard ST225, I can tell 
you from experience that putting a 'blank' ST225 in there just causes it 
to turn on the fault light. Whether there is some way to get the unit to 
do an LLF, whether you need a different firmware EPROM, or what, I don't 
know. But I jaut hope that disk keeps on working.
