I'm at a loss. I changed my cpu this morning from Intel Core 2 Duo E6700 to Intel Quad Core Q9450 and now my second year and a half old Seagate Barracuda hard drive isn't recognized at all, not even during post. I double checked all the cables to make sure I hadn't knocked one loose, and I switched all the cables and mobo ports to make sure that wasn't the problem. Any ideas?
You say it's the second drive - were you running a Raid configuration? It's possible the BIOS has returned to factory state with the CPU change (as it would have to in order to recognise the new CPU) - is there a seperate post POST RAID bios? Can you give more information about the rest of the config - what other drives, what motherboard, etc.?
nope, it wasn't in raid. specs are: XP Pro 32bit Intel Quad Core Q9450 4GB Patriot DDR2 800mhz RAM EVGA 780i mobo 2 hdds - western digital Raptor(still working) and Seagate Barracuda
elimination time - you say the Raptor is still be detected - if you swap the connectors (basically, plug the Seagate drive into the port on the mobo where the Raptor was, using the Raptor's cable) - is the seagate then detected. Basically change one thing at a time, we have a known good mobo socket and cable, so we need to use those to check if the Barracuda drive is working. Also, use the power lead from the Raptor. -- Just seen you already tried swapping mobo ports and cables - with no joy. Try just the Seagate drive on it's own, without the Raptor. Also might be worth checking if there's a BIOS upgrade for the mobo...
Hmmm - might be better to ask the question over the EVGA forums - I can only do limited diagnostics from several time zones away... however, it might be worth trying the hard drive in a different PC - just to prove it's still working, and didn't suffer some static shock or something during your upgrade. Worst case scenario you might have to restore onto a new disk from your last backup. You do have a backup? Try here: http://www.evga.com/forums/tt.asp?forumid=38 Good luck. (quick reminder to anyone else reading this thread - there are two types of computer user - those who have lost data to a hard drive failure, and those who are going to lose data to a hard drive failure. Take backups. Often.)
It's not broken because I took it out and put it in an external case plugging it back into my computer via usb after which I promptly made a new backup, my last one was a couple months old. so yeah...I don't get it.
OK - so it works in the external case, but not connected directly. Rules out the drive being faulty. Some SATAII drives (don't know if your Seagate has or not) have a jumper on them to reduce the speed to 150 - might be worth trying that - I've personally seen some versions of some motherboards (e.g the ASUS board in my current machine) just "not like" certain models of hard drive (e.g. the Samsung SATAII drive that I spent ours trying to sort out on my current machine) in SATA II mode. Although why that would start happening after the CPU was changed, I dunno. Did you need to update the BIOS to add support for the CPU?
