I have a laptop that is having problems (its a friends computer, Gateway) and I'm 90% sure the hard drive is messed up. I pulled the drive out and was going to stick it into another laptop I have (HP) as a secondary drive to see if there is a problem; when I pulled the drive out it has pins, similar to a normal HD, but the drive in my laptop uses a card type connection. This got me thinking, I need to order a new drive for this computer, what connection types are available? Is the card style connection an HP only thing? I was looking around Newegg.com and other than size and speed I couldn't tell the difference between the drives.
