I have an Emachine m622-uk8x and I would like to upgrade my hard drive. I have never upgraded a laptop hard drive and was just wondering if there are different types of hard drives with different connectors for laptops. I am just wondering this because I dont want to go through the trouble of getting a hard drive that won't go into my laptop. Can anyone give me any specs, especially connectors, that will work the the laptop that I listed above. Any help from anyone is greatly appreciated. Thanks.
