1) Alas, those instructions don't work for Roundcube. ;-)
2) I dunno -- it was pretty damn long-winded, but seemed above-board.
Me? I've *never* seen convincing proof that anything could be recovered
from a drive that's been completely overwritten once with *anything*.
I'm sure the DOD, etc., use crazy overwrite schemes, but the tolerances
are already vanishingly small just to store the data, much less recover
overwritten data. Not saying it's impossible, but unless you're worried
about the NSA, I'm thinking "one pass and done" is the answer. Almost
certainly preferable to actual degaussing, as that likely *would* leave
remnant bits, unless you just completely overwhelm it. Which is likely
beyond the means of old degaussing rings used for fixing CRTs and the
