I have a seagate internal 1tb sata1 Hdd yes I have had it for years and it was working. I installed windows sever 2008 r2 on it and worked fine except for little crashes due to Firefox plug ins. But for the past week it has been acting very, slow to open programs and keep them responding. I do not download anything to the server drive but had files on it before. Now it is doing something funky. I went back to the other drive that has windows 7 on it. When I first start it up, it sees the drive, even sees the drive until I try and do something to it. But after I try and access it it stops responding, could this be a total drive failure or something else?
