Erasing your hard disk drive
If you wish to sell, recycle or even just give your computer away, you need to ensure that you are not giving away your data as well.
There are a number of free tools which will IRRETRIEVABLY DELETE your data.
Be very careful when using these erasing tools, as without a backup (which you've got, right?) your data will be gone for ever.
There are a number of tools which can achieve this, and Viper Data recommends KillDisk.
