Hard drive not getting enough power?

post #1 of 4
Thread Starter 
I've got a Samsung HD502HJ 3.5" internal SATA hard drive, and ran into some problems with it while changing out motherboards.

The drive was not being recognized in the BIOS (the drive will not even turn on), but the other two hard drives and the optical drive showed up fine. I tried different power and SATA cables (from the other hard drives that I knew worked) and still nothing. So then I disconnected all the drives but this one. Still nothing.

I then unplug the power from the CPU (4 pin on mobo) and from the video card, and then the hard drive spins up just fine. But of course now my system is useless.

Is it not getting enough power to spin up? Is that possible, or is it something else? Any help is greatly appreciated as I am stumped.

Edit: I should not that I've got an 850W power supply, and I'm only running one video card, 3 hard drives, an optical drive, and 4 fans.

That PSU is more than capable to run that system. Check your connections again, try a different sata port on the board.

Could just be a dying HDD. Did you try checking disk management in windows?

I plugged it into my Mac laptop using an external hard drive adapter and I was able to get it to spin up and I could see all the files.

I know it's not a SATA port problem because the drive wasn't even spinning up. I tried multiple power connectors.
