Well Windows loads awful slow, I go to open Firefox, and it would take 30 sec to open. I just restarted it, and it said a SMART failure has occurred. Back up data and replace hard disc. A failure was immanent. Pressed F1, and Windows wouldn't even load. Gol darn check disc hung up on stage 4, probably due to a major error on the disc, so I did a force shut down. Well I think that wiped out some of Windows files. The guy that bought it from me, kept formatting it, installing different operating systems on it. Think that's how the drive became unreliable. I just sent it packing sooner.
