I agree. To worry about microscopy on the drive, it means that the FBI/CIA/NSA or another TLA is after you ... in which case they'll probably just kick in your door if they know where you live (which they must if they are stealing your trash). I personally "dd if=/dev/zero of=/dev/hda && dd if=/dev/urandom of=/dev/hda" and then run a drill bit through the drive (not right down the middle of the spindle, but somewhere to the side but still hit the platters). I think I drill moreso because it's fun than any other reason, though :) Really paranoid places have grinders that can reduce any media (drives, removable devices, CDs, etc) to a powder.

For the 99% case, "dd if=/dev/zero of=/dev/hda" from a linux distrib booted to a shell will probably suffice. Or maybe from /dev/random, which would take much longer. I wouldn't think scammers in Nigeria or wherever are the ones going after old drives with magnetic-force microscopy or in-depth head-signal analysis... Clearly, the answer is to fill the drive up with pr0n and then send it off! _H* _______________________________________________ Dataloss Mailing List (dataloss () attrition org) http://attrition.org/dataloss Tracking more than 142 million compromised records in 303 incidents over 6 years.
