Scream?  Or buzz?  We had a TU77, and when we ran backups, 
it made a loud buzzing as it was doing start/stop about as 
fast as it could go.  Or, are you referring to the whine as 
it went into rewind?

The 200 IPS Hitachi drives on our 360 were much louder in 
the rewind, you could hear it anywhere in the machine room.
