We've got a donated 7933 washtub drive that we can't seem to open.
We connected power to it, switched to UNLOAD, and turned it on.
Once the display shows STOPPED, we should be able to press UNLOCK DOOR
and open the top.  Nothing happens when we press UNLOCK DOOR.  Is there
something we're doing wrong (besides following the 7935 manual :-)?

Thanks for your replies,

The 7933 is an early model of the 7935 that did not have the option
to remove the media.  The "unlock door" button that is shown in the 
7935 documentation should in fact be unlabled on the 7933.

If you *really* want to get that pack out, it is possible.  Beware
that the 7933s are not supported with pack removal and that this is
not official advice from Hewlett Packard.

At the back of the unit, the top section has several ventilation slots.
One of thos slots will be slightly different from the rest (too lazy
to go into the computer room, write if you need more detail).  Insert
something into that slot (not much force should be required, HP name
badges work rather well) and the back end should lift.  Remove the top
and the door mechanism will be exposed at the front.  Notice the labels
that tell you what to not do.  Do that :-)

Like I said, you have to *really* want to change packs . . .
