Destroy Your Data

We've shown you how to hide your data , as well as ways to encrypt it. But what about data that you're done with —those files and folders that you don't want anyone to ever, ever see? You have to destroy them. And if you think that's as simple as dragging items to the Recycle Bin icon on your desktop, think again.

In other words, thanks to the way computers work, data is not gone for good without some extra work on your part. Hard drives and operating systems make you think data is deleted after you empty the trash, but it isn't. The space is just available for new files. Anyone with the right forensic tools—yes, think CSI if you want—can typically revive data you thought you were rid of.

Luckily, you can recover deleted data too. So when you accidentally delete a file, it doesn't have to be a disaster. But if you want that data truly destroyed, you have to shred it and over-write where it lived a few times, and then you can go on in peace, even if you sell the drive later. (In order to be sure that data can't be recovered, take that hard drive out back, drill holes in it, shoot it with grandpa's shotgun, smash it with a ball peen hammer, and set the remains on fire.)

Nuke It: Hard Drive Wipe
If you're going to pass an old hard drive on to someone else and you want to make sure the data once on it is never seen again, you need to security wipe it with a digital tool that will over-write it enough times to make it impossible to recover the data. Just doing a fdisk erase from the command line is not enough.

Overwriting usually comes in a couple of forms: the Gutmann method , which calls for overwriting data 35 times, and the U.S. Department of Defense's recommended method, which is seven overwrites. In addition, there's the Pseudorandom Number Generator (PRNG) Method, which uses random data in just four overwrites. Guess which one takes the longest? Doing 35 overwrites on a large-sized hard drive can take days. Literally. The DoD method and others should be fine. In fact, the Guttman method performs operations that might not even work with modern hard drives, so stick to a smaller number of over-writes.

Note, you probably don't have to go through this intense of a process if you're just going to reinstall the OS for yourself. A simple disk format should be fine.

A perfect—and free—tool for the job is Darik's Boot and Nuke (DBaN). You can download the software as an image and write it to a CD-ROM or USB flash drive using a tool like ImgBurn, and then boot your computer with DBaN as the temporary OS with one mission: keep writing over the disk until it's done. You can pick a quick erase, DoD method (three or seven passes), PRNG, Gutmann, even a data sanitization method created by the Royal Canadian Mounted Police that will do one to seven passes.
