A single pass wipe, with verify. The product I’d recommend?
Active@KillDisk Free. The free version only does one pass, so there’s not much to configure. It was a close tie between this product, and my second choice, Darik’s Boot & Nuke.
The feature which won me over? The utility to create a bootable USB memory stick “kill disk”.
Second choice: Darik’s Boot & Nuke.
DBAN is the choice most computer technicians I know make. I tripped across the “let’s hang if the laptop has a card reader” bug. That put me off DBAN. I’m sure it will be fixed soon.
BCWipe. The only commercially targeted product which offers a fully-functional evaluation copy. That counts for a lot in my opinion. BCWipe is also being actively developed (another plus). Go read my test of BCWipe for the rest of the details.
