i'm not all that experienced with computer hardware, but i know when something isn't working properly. I noticed that my hard drive activity light was always on, and that it had been that way since i had unplugged and replugged the cable into the primary drive (this was a separate issue that was solved by simply doing that). When i unplug the primary drive cable, the HDD activity light reverts to normal and it flashes along with activity from the backup drive. I am able to put the right half of the primary drive cable into the slot and it will be fine, but once the left half of the plug touches the metal, the light goes on and stays solid. I have no idea what to do or what it means so i would really appreciate some help
