I'm about to get rid of my 10-year old XP PC and replace it with a brand spanking new Windows 7 machine.

After I've transferred all my files, photos, etc from the old machine to the new machine, can members recommend the best free software to 'nuke' the old HDD so that info cannot be retrieved from it?

If you do not want to physically cut up or shred the HD ( I used a hacksaw on my very old 10gig one) There are a number of drive erasers, but I would look at CCleaner. In Tools,Drive Wiper, you can choose various overwrite settings.I would have thought that after you have deleted your data files and use the 7 passes option, all will be un restorable.Have a look: CCleaner

Other than completely destroying the old HD by smashing/burning/dismantling, it is just not possible to completely wipe a hard drive.

I would advice replacing the drive with a new empty drive, or sell it without a drive.

I have very recently done the same thing, bought a shiny new laptop and gave away my old desktop, minus its' drive which I have retained and will re-format to use as spare capacity.

I'd put the old HDD in a caddy and use Ccleaner's drive wiper.

Thanks for your responses.

I've always used CCleaner to 'clean' my HDD but never realised it had a 'wipe' facility as well!

Looks like that might be the way to go.

my preferred weapon for wiping hard drives is killdisk

if you fancy a look download create a cd from it then use cd to boot machine

BTW the CCleaner wipe on 7 passes takes a long time, maybe an overnight job.

7 passes stick with Ccleaner then free version of kill disk only passes once

Yes but the OS will remain on and do ensure you delete all data first.

If wanting to keep a copy of XP on the drive, I would re-install from the CD, or Recovery Partition, then wipe the empty space.

It's too difficult to find everything and delete manually, before wiping.
