No. Do not just leave your XP on there, your files will be easily accessed. Completely wipe your hard drive with the program I linked on my first post. If you are selling only the hard drive, it won't do any good to leave the OS installed anyway as the person that buys it will have to install their own OS with their own license.
FYI, to get to Disk Managment, click Start, right-click on My Computer, click Manage.
