Hi all, I'm looking to add another hard drive to my PC and have a few questions. The one already in it is a PATA drive, is this any different to a SATA? I have a spare ribbon cable thing from the other hard disk and a power supply, is there anything else I need? The cheapest 500g drive I found is the Samsung from ebuyer here, is there any where I can get one for less? Many thanks in advance for any helpful people that can sort out a luddite.
