Thanks for the sympathy. However, now it's a challenge and part of the fun will be making it work in the end.
I had partial success today using the HP Format utility that you linked to. However, after displaying the Windows XP splash screen it goes into a "Blue Screen of Death" with a 07B stop error.
I feel a little better since my limited research shows that I'm not the only one with this error. So... I'm almost there!
