It may not erase all data if the device can do block relocation and you
don't have direct access to phisical blocks. But if data remains on
hidden or discarted blocks it is still hard to someone else recover it.

Another route to securely erasing information is encryption. OpenBSD
includes at least 3 systems for disk encryption (svnd, softraid, and
cfs (ports)). I've personally used cfs and svnd, and as is usually
the case on OpenBSD, both work nicely once you RTFM. (I should really

that after overwriting it 1 time you can't recover data anymore with
