So one pass is fine for most situations where the potential value of any recovered data is far, far less than the cost to attempt to extract it.
Describes this situation perfectly. But to be even more safe I did the 'single pass' option twice.
A few years back I did destroy a HD manually. Broke one screwdriver and a claw hammer in the process. Hardly therapeutic!!! Worst part is you can't buy claw hammers here, and you can't bring them home in carry on!
Now does anyone want to buy a 40GB La Cie Hard drive, that is the size of bread box (almost)??
