How much wiping do you do? :)

The issue is mostly theoretical from my understanding.  No one with  
the exception of the NSA has the equipment to even potentially recover  
that data.

My advise: Don't put anything on your disks that the NSA would be THAT  
interested in finding.

So out of curiosity, Degaus of tape media - will that render the  
tape useless also?

Unclass drives are just overwritten since there's really nothing  
on them
that is worth the national lab type of attack necessary to get any
residual bits off them.

Just for the sake of everyone on-list, it may be worth noting two
things about degaussing:

1. A strong magnet or a bulk tape eraser won't cut it for hard drives.
You're using a special-purpose degausser, probably a Garner model?

2. Degaussing also erases the control track information, which means
that you can't reuse the drive. It's like shredding without the sharp
edges.
