I just got a new 750gb SATA HD to stick in my media PC. Well it didn't work when I put it int he media PC. So I stick it in my desktop and it works fine. So I go back to the media PC to troubleshoot. It isn't even coming up in the bios. By doing some guess and check work I find out that if I just attach the power cable the drive spins up just fine. If I then stick the SATA cable in it, it does nothing at all. Could this be a short or possibly something else? I've never really had to deal with a short before so not sure what the best way to go about it all is if I have one. The motherboard is it being hooked up to is an ECS KV2 Lite.
