I use dBan @ http://www.dban.org

I like how you can purchase a signed certificate from them. Pretty cool. There is also a free version.

The proper way to wipe a disk is to destroy the encryption key, if you know what I mean.
 
unRAID has the preclear script which checks, wipes, and verifies the drive. Sure a 4TB drive can take a day or so but you get a fully scanned and clean drive and you know if you have any bad sectors or not. Takes all the guess work out of the way.

Works for both SSD's and HD's. Yes doing it on SSD's is overkill and a waste but I'll never approach the amount of writes in the drives lifetime how I'm using it anyway.

Also 11 passes is insane. The paper linked above is correct. 1 pass will do.
 
Block level wiping is pretty old hat at this point and not sufficient for sanitizing data anyway as LBA is an abstraction of physical storage and not a direct mapping.

If you're wiping a drive you should be using the ATA Secure Erase command. On HDDs using FDE and most SSDs this command is very fast.
 
I prefer military grade wipes using military grade 5.56mm NATO rounds. It saves time and is cathartic after a long day at the office.

Actually you can still recover data from that as you aren't destroying the data, just the drive. If you don't want to bother with doing a drive wipe but still want to destroy the drive with no data recoverable, thermite is the only (awesome) way to go. (yea turning the whole thing into dust also works but isn't as fun as melting it :D)
