How much wiping do you do? :)

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

In my world, disks with sensitive data are either zapped in a degausser
or dropped into a shredder.  The customer doesn't allow overwriting of
any kind.

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.
