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.

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?
