The only 100% secure way to destroy the data on a hard drive is to remove the disc and physically destroy it.

As I understand it you cannot "wipe" the encoded information.

However, there are programmes available that overwrite the data (with random ones and zeros I think) on the drive multiple times to make the data unreadable, the more times it's overwritten the more unreadable it becomes.

Free software such as CCleaner has a facility in the tools menu to wipe the drive - their most secure is to overwrite 35 times, but it will take a long time to do this.

CCleaner is also good free software to give your computer a spring clean and clean out all the rubbish that accumulates over time.

If you don't intend to use it - don't mind losing software on it - you can reformat the disc(s) as a simple step. Probably not as effective as CCleaner but it works for most purposes

Its how far you want to go in some ways - the chances of someone being bothered - how vital the data is - how much of it actually matters security wise.

There is a lot of standard software around which will recover data from a formatted disk ... ls-2622893

You could look at article such as ... ve-2624527 you will get a better idea of what to do.

Then you really might want to run a data recovery progam just to make sure...

Or you could buy a hammer to destroy the old and put new disk in!

If you are really that worried, hard drives are so cheap now that its more expedient to take the old drive out, destroy it and replace it with a new one.
