Err...okay.
So, I did the EvoX backup on my original HD, ran LiveInfo on the new disk, all is good.
I pull the computer apart, remove my cables, and plug in the Xbox HD as Master on IDE 0, and and the new HD as Master on IDE 1. No other devices present.
I boot off a floppy, run ATAPWD, and I only see the new HD. I reboot, look in the BIOS. It shows up there. Try ATAPWD again...and the Xbox HD still doesn't even show. I run hdunlock as well, just to see if it's a glitch with ATAPWD, but that also reports that the drive is MIA.
Using Cable Select instead of Master changes nothing.
The mobo I'm running on is an Intel P3 board...815E I think. I remember reading bits about 820/815 chipsets not liking ATAPWD very much. Could this be my problem?
I'm gonna put my work computer back together and try this on my Athlon at home. Hopefully that fixes things.
