If the data is valuable to you the consideration of commercial data

hello,
i have a Lacie 500GB external harddrive that's been sweet and i've
stored a lot of stuff on there. Essentially what's happened is that
it's stopped working and the usual sort of spinning sound of the disk
in the hard drive has stopped and now makes a repetitive tzz tzz tzz
sound that's relatively quiet. What i assume is that the data is all
there and recoverable and that it's just some other mechanisms that
have screwed up. What can I do?


It might be possible to replace the motor driver chip, or swap the circuit
board over from an identical drive. I've fixed a drive once by replacing a
mosfet driving the motor but that was an old drive with discrete parts
while most today use one big IC to do that stuff.

This is precisely why backups are so important.



All good suggestions if the logic is the cause of his disk motor not
working. His comment regarding the "Tzz, tzz, tzz" sounds a lot like it
might be the heads sticking to the platters. If this is the case, a
jarring of the drive into the palm of your hand while power is applied
might free up the heads. Older drives encountered this type of problem
frequently. It is true that newer ones encounter this less, but it
might still be the problem rather than bad logic.
