If I remember my rudimentary disk drive stuff from when I
played around with them on my Apple computer....

Each disk drive has it's own unique set of commands which
tell it to spin up/down, lock/unlock, etc....  In order to
even start working on this I would have to assume that
you'd have to contact the manufacturer and find out the
proper commands.  That is - if you want to do this
directly.

If you have a program FROM the manufacturer which will do
this for you, then you should be able to do this with an
AppleScript (although I am AppleScript stupid myself [soon
to be remedied when I get paid again and can afford to buy
a book on AppleScript]).  :-)
