I've heard that laptop hard drives get their power and i/o from the cable that connects it to the motherboard, so I don't want to risk assuming the laptop hard drive is like a normal 5.25" hard drive (which always have pin 1 and 2 closest to the power input). I looked around on google and yahoo for a few hours with the keywords "3.5" hard drive, pin settings" or "3.5" hard drive, pin numbers" but all I was able to learn was that the four separate pins are jumper pins.
... So umm.. on a laptop hard drive, where is Pin1?
PS - is a 3.5" to 5.25" adapter stable enough to be used as a long term set-up? (as in, would I be able to use the laptop hard drive like a normal 5.25" hard drive once I have it set up correctly?)
