If you want to be super paranoid about things, use properly implemented
full disk encryption from the get go. Once you are ready to wipe the
disk, use what is standard for most Government/Business use: overwrite
with random data 7 times. If you want to be super aggressive about
things (yet for

I don't have a solution to offer for existing disks, but that made me
just think that it would be probably easy to create two partitions on a
disk, one that will be a keydisk

Thanks to all of you for either useful tips or good-to-read rants. :-) I’ll
try out tips from Nick & Todd, let’s see where that takes me.

You need to use an 8 to wipe out all seven segments.

Don't bother. Wiping the disk twice is enough. If you are storing state
secrets melt the disk.
Back in the days of sub 1G disks it might have been possible to get inter
track gap data that was usable. Maybe. But not multi T disks.
Sectors mapped out are a problem though, and multiple wri
You can adapt my linux bash script for such pointlessly "paranoid"
purposes. I use it to prove to HIPAA auditors just how paranoid I can be,
and it's above NIST requirements in the US.

Would require you to pkg_add pv base64. Or, just adapt the script without

writes 512 bytes with all bits set. Feel free to use larger numbers
than 512.
Hi!
Again, an ignorant question (as usual):
How might I do something similar to
# dd if=/dev/one of=/dev/sd0 bs=1M
as a complement to the usual and well-described
# dd if=/dev/zero of=/dev/sd0 bs=1M
followed by
# dd if=/dev/urandom of=/dev/sd0 bs=1M
in order to achieve paranoid disk-wiping?
