How can I permanently erase information from my harddrive?

If you want to permanently erase information from your hard drive, sending the files to the Recycle bin and then emptying it is simply not enough. Even though the files might eventually be overwritten sector by sector, they could be partially or entirely recovered with specialized software.

If you need to permanently remove files from your computer you can use a free little tool called Eraser which completely removes sensitive data from your hard drive by overwriting it several times.
