An easy way to do this is to boot with a livecd and the copy /dev/zero to the raw disk devices (or use a destructive write test with badblocks). Once that is complete do a fresh install. Recovering data from reallocated (by the disk drive) sectors (if you even have any) would be difficult and would not normally be much data. Recovering data by looking at the platter with say an electron microscope and trying to recover traces of old data isn't going to be economically feasible.
