My Toshiba Satellite (just 2 years old) updated about 3 weeks ago to 8.1. I didn't bother my computer until a couple of hours later, when my husband noticed the hard drive failure message. The computer started slowing down also immediately. It took a couple of days to scan the drive for errors and it did not find any. I tried to run my virus scan and it would not load. I even tried to backup my drive before replacing and it has been a nightmare. Is there any way that I can just change the drive and start from scratch without dealing with the original drive?
