bc-wipe isn't safe, period. At best, it offers a probabilistic
erasure. At worst, the underlying sectors may have been remapped
silently by the drive, or moved and left behind in the normal
FFS allocation strategy to reduce fragmentation.
The m*of the story: you can't rely on overwriting irrevocably to
delete sensitive data.
