I didn't look that closely the last time I opened my A3000, but if there's
space, you might be able to do it.  To do it right, I'd use some type
of bracket to tie-down the second drive and insert a little gap between
the two drives.  You'll also have to watch the mounting bracket on the top
half of the case.  If it physically fits, then there's no electrical reason
why it shouldn't work if you mind the power, SCSI cabling and terminators.

Heat could be a problem.  I just don't know about the cooling paths and
capacity of the A3000's airflow.

As for the HD activity light, that's tied to the controller and lights up
whenever the controller accesses the SCSI bus, so accesses to either drive
will cause the light to flicker.
