ok so on every sata drive(laptop or desktop) that there is a 4 pin connector next to the power and data connectors. What is this for, i couldnt seem to find out on the internet and im curious?
 
Solution
Those are actually jumpers (some drives have 4, some 8), although not generally used. HERE is an explanation of what they do on WD drives, and HERE for Seagate, which is pretty much just to set the drive to a 1.5Gbps mode.
