As could I; my past experience was 8 years in US government ciphony. But
I have to admit that I'm still getting a handle on linux security, so
I'm always open to learning all that I can. However, the OP was looking
for something to wipe his disks for donation & shred was mentioned -
scrub was offered as an alternative. The caveats in the scrub man doc
offer sufficient warning about it's limitations.

Personally for a non-government standard user use I like bcwipe for
linux (non-free). Alternatively I use a blowtorch :-)
