My internal SATA HDD spins, but it's not detected.

Hello!

I've three internal Seagate SATA HDDs installed on my computer. I hooked one of them up in the hotswap dock of my friend's pc to transfer some data, and when I plugged it back to my pc, it's not detected at all. It is undetected in "My Computer", "Disk Management" and "BIOS". It spins and get a bit hotter than the other drives. HELP!

HDD Model: Seagate Barracuda 1TB ST1000DM003
PC Specs: In my signature.

it spins but can you feel/hear the heads moving? most likely if it is spinning like that and not seen by anything in PC I'd say its toast. if the PC can't see it you have no way to attempt recovery/diagnostics.

Check again the sata cable in both ends, but unless it's that simple mistake then it seems your HDD is gone, with luck it's only its PCB which you could replace with another identical to retrieve your data.

I had something similar happen to me recently. It turns out that the firmware was corrupted and the system area was damaged. Your MBR might be the issue in that case.

Hey there, FaroukZidane!

Besides what all the other guys mentioned, I'd suggest you to try the HDD in a different computer or even with a different SATA cable and see if it will get recognized somewhere there. This way we can actually determine if the fault is in the HDD itself or somewhere else in your system.
Another thing that might help getting the drive detected is resetting BIOS by re-seating the CMOS battery or setting the jumper on the motherboard. Here's a tutorial with pictures that might help you with that: http://www.wikihow.com/Reset-Your-BIOS

Hope this helps you! Keep us posted with the troubleshooting!
