I'm working on an HP Pavilion P6210Y (Pegatron M2N78-LA motherboard) that's hard drive has crashed. The issue that I'm running in to is that for some reason the computer absolutely REFUSES to detect the replacement drive I'm attempting to install, despite the fact that I KNOW the hard drive is good as I just pulled it out a a striping RAID setup in which it worked flawlessly.

The HP's original HD was a Western Digital Caviar WD6400AAKS. The drive I'm attempting to replace it with is a one year older Western Digital WD6400AAKS. If I just hit the power switch on the machine it'll load to the BIOS POST splash page and just hang. If I hit F10 to get into the BIOS setup quickly then it'll load the BIOS, but only the DVD drive is detected. There is no hint that the hard drive is plugged in at all.

I've tried different SATA ports, resetting the BIOS to its defaults, using the same SATA cable that the replacement drive was using in the RAID setup in the other machine, etc. Nothing I've done will make this blasted computer detect that the drive exists. I've checked the P6210Y's product support page on HP's website and see no BIOS updates that I could try.

It worked in the RAID it used to be in. Test it again now on another system. If the mobo in that HP caused the original drive to crash, it could have damaged the replacement –  Bon Gart Jun 25 '12 at 22:12
Gets detected fine when connected to my test rig, was able to create partitions, format them, etc. –  Sootah Jun 26 '12 at 1:24
Then you may have discovered the reason/issue for the original drive crash. The motherboard. You can try another different drive, but at this point you should expect the same results. –  Bon Gart Jun 26 '12 at 1:31

I have experienced two motherboards of the same type fail in the same way and traced it to an overheated nVidia MCP chip on the motherboard which handles the SATA ports. This chip has a passive cooler and runs RIDICULOUSLY hot in operation as it is a single chip doing all the traditional "southbridge" and "northbridge" operations. If you dare to touch this cooler when the system is runnign you risk a burned finger! A quick look around the internet revealed this motherboard has a very high failure rate. As a re-seller I have solfd ~30 HP systems with these boards and am now trackign customers and offering to fir fans to the cooler to prevent overheating, leading to failure.
