I was sure there'd been a thread on this in the last few months, but
couldn't find it...

For any of you needing to zap drives before disposal, these links seem

Robin Harris Blog - "How to REALLY erase a hard drive"

Points to [PDF] "Data Sanitisation" by Centre for Magnetic Recording
<http://cmrr.ucsd.edu/Hughes/DataSanitizationTutorial.pdf> and

Quotes NIST 800-88 and DoD 5220 standards compliance.
Notes that degaussers may not work with next generation drives
And grinding disks into pieces smaller than 1 sector is used as well.
And newer 2.5" drives with FDE (Full Disk Encryption) done on-board can
be very secure.

Harris also mentions "Boot and Nuke" - haven't looked.

Hope this is interesting.
