I agree with fo3nix, use Eraser. If you want to permanently erase your confidential files now use the "Erase unused disk space" option. You will probably get error messages from windoze telling you the disk is full - this is what is supposed to happen because Eraser creates files and folders that fill up the disk and then erases them.
When it becomes time to reformat and install go into the BIOS and change the startup order to CD, then Floppy and then Drive C. Make sure there is nothing in the CD drive or floppy. The computer will boot normally, run eraser and select Make floppy, when it finishes leave the floppy in and reboot, when that finishes insert the install CD, remove the floppy and reboot. This will totally erase everything on all hard drives and start the installation of XP.
Instructions are in the
quick start guide.
NOTES:
1) Do not use the Erase Disk floppy if windoze reinstalls from a recovey partition because the Erase Disk wipes out everything, including the recovery partition!
2) Make
certain you have backed up everything you want to keep because Erase Disk will wipe out everything and you will not be able to recover anything.
This is exactly the method I use when I reinstall XP.
Oh yeah, 512MB of memory and 80GB of disk space is enough - I was running XP with 512MB of memory and a total 60GB of disk space (20GB and 40GB) for over 2 years without a problem. The only change I have made is to replace the 40GB drive with a 120GB drive - no faster, just more disk space.
