Getting Rid of an Old Hard Drive or PC? Remember to Wipe the Drive!

Western Digital WD10EZEX Hard DriveDid you know that when you delete a file from your hard drive, it doesn't really go away? Did you know that even formatting a hard drive (in most cases, anyway) won't do the trick? It's true.

When files are erased (and I use that term loosely) from a hard drive, they're not really gone, only the location information for the file is removed. In other words, the file(s) are invisible to the operating system (like Windows or Linux) but not impossible to recover.

So what do you do if you're selling or giving away your computer or computer's hard drive? Do more than just format it, that's for sure. What you need to do is completely erase the data in a way that makes it impossible, with current and probably any technology, to recover.

You can do that with special software called data destruction software. I keep a long list of free ones in my Free Data Destruction Software list. Basically, you boot from a disc you burn and then follow the directions given by the software. DBAN is my favorite of these tools.

Here's a general walk-through of the process: How to Wipe a Hard Drive.

Did you properly wipe the last hard drive you passed on or disposed of?
