[comp.sys.hp] HP Optical disk library

pschenk@cernvax.cern.ch (paul schenk) (03/08/91)

 Hi. We have purchased an HP optical disk library and have a bit
of a problem. We want to write our own device driver to
control the disk changer. We found an HP publication called
"Rewritable Optical Disk Library System. Technical Reference Manual"
HP part no. 5959-3540.
It's just what we need, EXCEPT the copy we have is missing pages
3-51 to 4-26. You guessed it, these pages describe the commands
accepted by the autochanger :-( .
Now the kicker. HP claims this manual does not exist !!!!
Sure. So how are we supposed to use this device?  Instead of
relating all my frustrations over this issue, I just want to beg
for help.
DOES ANYONE HAVE THIS MANUAL? IF SO, CAN YOU SEND ME A COPY OF THE
PAGES MENTIONED ABOVE?
Can anyone out there from HP Greely Storage Division tell me how
to order a manual that will describe the commands accepted by the
autochanger?

Thanks in advance.
Ciao,
Casper

We bought a rewritable optical disk drive from HP some
months ago and received no documentation at all with it.
I have heard that there is some way of (1) locking the
drive so that a disk cannot be manually ejected from it
until the drive receives some signal; (2) sending a signal
to the drive to eject the current disk.  Does anyone know
anything about this?
