    Depends on if you still want the hard drive to work after the 'secure erase' :-)

    I was once given a laptop hard disk to 'securely erase'. I dismantled it and discovered it had glass platters (when one shattered and nearly put glass in to my face). I returned the drive to the requester as a pile of bent metal and shattered glass. No way any one was going to recover the data from that one... :-)

    Apparently there are shredders that are powerful enough to mulch a hard drive for the really secure erase situations.

    Blast the HDD with a burst of high intensity ElectroMagnetic Pulse (EMP) equivalent to the strength of those emitted from a High-Altitude Nuclear Explosions (HANE).




    Step No. 02...

    Degauss, Degauss, Degauss... repeatedly till the HDD becomes as magnetically inactive as a piece of plastic.




    Or...

    haha. thanks for all your suggestions.

    but it's scary how when you sell your note book, people can retrieve confidential info if you are not careful.
