It is NOT impossible to recover data after scrubbing a drive. Just beyond
the capabilities of probably anyone but a VERY good data recovery lab and
the government.
The DoD M5220 and Guttman's Wipe are NOT algorithms, they just define how
one should wipe the disk. Guttman's wipe is pointless if it's a newer disk,
and he says so in his paper. If you want to make a disk as unrecoverable as
possible, just wipe it as many times as you can with random data.
