Windows 7: clean XP hard drive using win 7 clean commands?

Hi, I want to clean/erase my xp hard drive. followed the tutorial on this forum and got to cmd - diskpart - select disk - clean all - exit but it weon't do anything. I put clean ), O clean, cean all O, etc and it just says Im not doing it right and so nothing happens. I can't find any similar instructions searching XP except for reformat and I want to clean totally not reformat. thanks!

Whats the difference to you in terms of clean totally vs format. Format erases the entire drive as well.

The "clean all" command takes a while to complete, like 1 hour for 250GB.

I would like to get it to work :-) going to sell this computer and want the drive as clean as I can get it.

If you cant get Clean all to work, use DBAN to completely nuke the hard drive.

As bill2 says, DBAN you could use and i recently used it in a study i was carrying out and worked excellently and none of my hard disk could be reocvered.
You can take a look at a guide i just wrote below:

Hope it helps

Clean All is tricky. Once the command starts, there's nothing to let you know that it's processing. All you see is a blinking cursor. Don't let that fool you, it is in fact processing. You'll have to wait it out. When it completes (could take a couple of hours) It will let you know that the command was completed successfully.
