Hi all,
I ripped out my old HDD from an old pc and want to use it in my new custom build to save some money. The old PC is no longer in working condition so I was wondering if there was any way I could wipe my INTERNAL hdd in an EXTERNAL way. It is an old Seagate Barracuda 250GB drive that will do for now. I want to wipe it so I can install Win 7. Any help is appreciated! Thanks.
To "wipe" a hard drive means to completely erase the drive such that somebody who is trying to recover data from it cannot do so. This requires multiple rewrites of the entire drive with random data. You do NOT need to do that unless you are disposing of the drive. There are several ways to do this:
1. Boot a live Linux CD or DVD and use the "shred" command with at least three random passes ("shred /dev/$device -n3".)
2. Hold a really strong electromagnet next to the HDD and cycle it on and off a few times. It takes a really strong one to do this- think closer to an MRI machine's electromagnet than a doorbell's electromagnet.
3. Take a decent sized high speed steel drill bit (I recommend 1/4" or better) and drill a few holes all the way through the drive.
4. Hit the drive with a sledgehammer until the cover breaks off and the platters turn into a bunch of little glass slivers.
5. My favorite- take your favorite rifle, high-velocity handgun, or slug-shooting shotgun out and pop a few rounds into the drive. I'd pick a typical deer rifle as a .270 or .30-06 will certainly poke a hole through even the toughest drive, but something little like a .22 may not go all the way through a 3.5" drive. If you have a bunch of drives, get a .50 BMG and line them up like dominoes. Then shoot through all of them with one shot (look for the YouTube video, it's a hoot.)
However, you just want to *reformat* the hard drive. Just put in the Windows 7 disk and do a "new install." That will automatically reformat your drive and allow for a brand-new copy of Windows to be installed and get rid of the old one.
