Hello. Recently I tried to install Windows XP on an old HDD I had lying around for better compatibility with certain programs. The installation seemed to be doing OK until I got a "Data Error (Cyclic Redundancy Check) which I have read is from bad HDD's. I figured no harm no foul and went to go back to Windows 7 on my other Hard drive to check the other one but when I went to it, it failed to boot. The BIOS screen said "Windows could not start because of a disk hardware configuration problem." I'm seriously very mad at this point as I did nothing to the other HDD to cause this problem. Any suggestions on how this could be fixed?
