I don't have enough details to tell you which but the good news is the XP SATA hard drive issue is well discussed so I don't have to write more about that.

I was reformatting my neighbors computer, but we have ran into a problem. After finishing partition reformat his disk, we received a error that said:
A disk read error occurred. Press CTRL ALT DEL to restart.
The error appeared on bootup.
We were running on Windows 7 but downgrading back to XP.
What could be the problem? Thanks!
