Thank you everyone for your input.
I'm pretty satisfied that this HDD is dead.
I bought a simple adapter at Fry's and mounted the drive in a 1394
box. I deliberately left it open. When I powered it up, all I could
hear in the vicinity was the fan for the box.
I pulled up the full manual for the HDD from a very hard to find
Toshiba url: http://sdd.toshiba.com/main.aspx?Pat...Documentation/
It is for their storage device division and you don't find it on the
There I downloaded a 136 page pdf file and learned that pin 42 is +5 V
and pin 43 is one of many system grounds. I connected them to the
appropriate terminals on a 5V DC power supply. I could not hear the
motor spin up. Am I correct that applying 5V to these pins will spin
up the HDD, or does the controller have to send a 'start the motor'
signal as well?
Am I correct in concluding that something killed the drive and the
motor probably no longer runs?
Am I correct in concluding that without a motor that works much hard
work ($$$) needs to be done to replace it so that the contents of the
disk can again be read?
