How much wiping do you do? :)

The Garner model I'm familiar with does HDD and Tape media, quote from the info sheet... "complete erasure"

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

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.
