Wooha - it opend automaticly ? Dangerous. The first thing I
learned on head crash was:

Stop the unit
Unplug power
Unplug Interface
Roll the unit out of the computer room
At best out of the house
Now have fun with the damaged parts :)

At all this steps (but the last), especialy when
a delay ocures, guard the top with your life.

We once had a 144 MB unit crashing on saturday
morning and running (the check logic was damaged)
until monday morning (no operators). The heads have
been scraped completly, and the crashed disk was just
pure alu - no magnetic surface left ... The fun thing
was that parts of the disk stack had been readable until
sunday night ... We couldn't belive the transaction
protocolls :)
