so I finally got my new hard drive for my laptop, and I found a big problem. it doesnt fit! I got a 2.5" SATA drive and my notebook has a SATA 2.5" drive in it, theyre both even the same drive (seagate momentus) [I dont have much experience here, so please forgive me if this is an obvious question] the problem is, the drive in my notebook isnt regular SATA. I checked it out, and instead of the flat row of pins you would expect, it has these thin "plates" that are almost as tall as the drive sticking straight out. they slide into little grooves in the connector in my notebook. I've never seen this before and I couldnt find any info on it. but without any idea what this is, I have no hope of buying the correct drive. so what is this? and is there a possible way to use a standard SATA drive?
