I've got one at work like that. I thought I'd try recovering it with 
dd rescue - partly for the experience. Didn't take long to give up on 
it !

Also, I'm not 100% certain, but I think it also managed to lock up 
the host controller as well. I found that pulling the power cable to 
the drive and reconnecting it didn't bring it back to life - while 
power cycling the whole machine did. So I put it on an external USB 
adapter so I could power cycle the drive & controller without power 
cycling the machine as well.

Enough to put you off a Seagate drive. Any half decent firmware would 
report an error and carry on - leaving the OS to decide how to deal 
with it.
