Since you have taken the disk apart it will now be useless as within the
enclosure there could have been a vacuum or an inert gas.
You will never be able to recover any data on the disk unless you go and pay
for a professional data recovery organisation to read the platters.
The price for a replacement 340GByte USB disk is about $25 which would give
you a better product than your old disk.

but when it is powered on, the head first moves to the center of the
disk,
then to the periphery and finally back to the resting position. This

nothing.
That repeated seeking suggests it's not passing its self test, and is
constantly retrying. It's probably searching for servo data on the
disks,
and not finding it.

I see. I have not searched for any low-level disk utility from Toshiba, the
manufacturer of the disk. Do you think that might be worthwhile to hopefully
fix this?
