   For example, I
have disassembled the firmware of the HP 7958A and found
 out how to low-level format a foreign ESDI disk (the original one had
 failed) with different geometry (the geometry is read from the drive since
 it is ESDI). In this case HP-UX mediainit in guru mode was my friend. 
 I hope you've kept a record of this procedure. It's the sort of thing
 others may have to do sometime... 
 
Of course; it wasn't trivial to find the correct parameters (I think that
I even had started to disassemble the PA-RISC binary of mediainit until I
found the instructions somewhere on the net). After all, it is basically
sending the CS/80 "INIT MEDIA" command with IIRC function number 3 (which
is undocumented).
