I am trying to get my Powermac G4 (1x500) to update, but it always gives me a 1001 error. I recently installed a larger Hard Drive, a 120GB Western Digital WD1200. I doubt that this has anything to do with the issues, although it is the only difference between getting updates and not getting updates. Plus, I know it isn't the Powermac, as I installed another hard drive from another mac and it did updates just fine, so my Ethernet port is working.

Any ideas where the problems might be?

Thanks!
