    Another option is to sell the laptop without the hard drive. But that might put off a few potential buyers. Thanks!

    reinstall the system software from the included CDs. Choose the 7x wipe option.

    The 1-time wipe should be all you need. Anybody who can demonstrate the ability to recover data from a drive that has been wiped is free to post it.

    I'm sure the guy in the other room who installed XP over his OS X would like to know about it.

    if you want the *most* secure way to wipe the drive you can use disk utility and do a 35 pass zero out, which will take hours. Really 1 pass will probably be plenty, but you did as for the most secure.

    1-pass wipe is more than enough. more than that, anyone needs a special device (very expensive) to retrieved overwritten data.

    Like the guys (or girls) above said; the 1 swipe will be more than enough, unless you have some files the FBI or CIA is looking for :rolleyes:

    Most accurately, there is none. Other than smashing you HDD into pieces. Though, I'm sure someone could always piece it back together.:eek: People have demonstrated recovering data after OS installations, reformats, and 3rd party wipes. Though, you should be fine with a single wipe, as others have said.:p

    Only if the software was coded poorly and left some space unwiped.

    Or, if they had the equipment to take the drive apart and examine each bit with a specialised electron microscope to determine what the previous data was.

    See here for a little explanation:

    A 7 pass erase should prevent that. Of course, a single pass is enough, unless you have something really worth hiding.
