Hello! A few days ago I tried to put a HDD from a laptop into my PC. When everything was connected, I tried to start it. No reaction when pressing the power button whatsoever. When I took the HDD out, the PC starts up as if nothing had happened. BUT before that, I inserted another laptop HDD and it went w/out issues. So, is my PSU unable to power the other HDD or is it the HDD that's having problems? P.S. the one that worked was like 10GB and the nonworking was like 40GB; My PSU - 350W Generic
Yeah, it probably is that the PSU is just enough to power your current system, but anything else added in and it fails to boot. You might just hook up the hard drive without installing it in your case just to make sure there's no shorts (which I doubt, but worth considering).
But in that case, how come that one HDD worked and the other didn't? Is there really so much difference in power consumption between a 10GB disk and a 40GB disk? P.S. just connected a 80GB PATA drive to my system and everythings stable... now I'm really confused...
Hard drive's consume very little power, so the capacity should matter very little---if anything at all. Now that you've tried another drive, it could be the one hard drive itself.
Thanks this far, Big B! The drive works pretty fine in it's native machine, so it's a mystery still... I connected them (both are from the same type of Walkabout tablets) in exactly the same way (PATA -> small convertor -> tablet HDD) to my PC.
