Thank you all for your quick responses,I have solved the issue by downloading a program that rewrote the faulty(new) disk back to all zero's. And then by setting up the faulty(new) drive by running it as a slave to a working hard drive, downloaded a hardware cloning software and made a copy of the working and burned it to the new one. I powered down, reset the jumper setting on the new drive and removed the old one and voila! It works. the funny thing is that it was the 3rd hard drive that wouldn't completely boot from a good winxp cd. I purchased them all new and each one was deemed "faulty" by the tech support at Western Digital.. The drives would boot from cd, go through the whole process and then once windows would copy files to disk, it would never go to the windows setup screen. it would just try to reboot but at that point the screen would stay black at the "windows is checking the configuration of the hard disk" Thank you all again. does anyone have a clue why the set up wouldn't complete after going through the whole process of booting from cd? i know it was formatted correctly because it would run as a slave to the prior hard drive. I am new to working on my own computer so please be gentle,lol.
