Hello, I am trying to help a friend out. I am a help desk level one person by trade but most definitely out of practice and my tools are out of date too. Friend has two duplicate Dell desktops one looks like a bad HD that is FUBAR. I am trying out the HD from the other. The first HD is a Seagate Barracuda 7200.9 SATA drive and the other is a WD Caviar SE SATA. Both computers are Windows XP Pro but I only have my old XP home disc to use from my old no longer in service XP desktop. I have tried loading the system from both what is originally on the WD drive and to run the Windows XP Home setup I have. I get the following three error codes: 0x0000007B 0xF7A8E63C 0xC0000034 Since both of these machines have been around the block a few times I am willing to believe both drives are FUBAR but before telling the guy that I wanted to run this by others. I don't have any spare CDs to burn diagnostic software to disc to run and the diagnostic software I have is really ancient as in from when XP was still relatively new, I worked for Geek Squad and the disk technology that was current was still IDE/EIDE......so it won't work for anything SATA. Any suggestions? Thank you.
