You can use the process below to completely wipe your Hard Drive, but you must have your set Recovery discs to reinstall the operating sytem if you wish to sell it with XP installed.
Download and install Killdisk on the link below - ( this application will write zeros to the entire drive ).
Download and install ImgBurn on the link below.
Go to the Kill Disk application you have installed in All Programs, open the main folder, then select Bootable Disk creators and from that select Bootable DOS CD Creator which will burn the bootable ISO to a blank CD.
During the next process do not worry about any warnings as your Recovery DVDs will reformat the HDD.
Insert this CD in to yout notebook. Shut the notebook down, then start it again to boot from the Killdisk CD and follow the on screen instructions for Kill Disk.
A brief description of the process is here Killdisk.
Use this to wipe the whole of the Hard Drive, highlight (80h) and press f10 ( you will also have to type a confirmation and hit enter ) - ( this will make sure you include all partitions and then start the process - this may take a couple of hours! ).
When the process is complete, remove the Killdisk CD, insert your first HP Recovery Disc and restart the notebook to run the installation.
