Wiping data from a hard drive.

[Tab Gilbert]

I just came across this interesting article on data recovery and solid state
drives.  Not sure how TRIM would work with Ubuntu but I like the concept.

TRIM is a brand-new ATA command that the OS will issue to the SSD when a

So maybe the solution is destroy this one and go with a solid state drive.
To bad it is not a cheap option at the moment.
