My parents bought an Acer Aspire 5315 Notebook for me a few months ago. After having it for a few months, my hard drive broke, so I contacted the company. I sent in the hard drive to get a free replacement. When I removed the hard drive, I also removed a rectangular, three-sided metalic piece that screws into the hard drive and laptop itself and sent it in with the hard drive. When I got the new hard drive, this metalic piece was gone. I've contacted Acer multiple times to try to get a replacement, but no one seems to know what I am talking about when I describe the metalic piece. Does anyone know what that rectangular, three-sided metalic piece is called? Does it even really have a technical name? I wasn't sure if knowing the technical name would help me obtain one from Acer or somewhere else. That leads to my next question. Does anyone know where I could get one of those pieces that would fit my computer and hard drive?
