I've had this error for awhile and have ignored it for some months. I think its time for me to start addressing the problem. What are the steps I need to do to fix this problem? What are the tools I can use to back up? I also want to upgrade to a newer Windows operating system. Wdc wd10ezex-08m2na0 is the problem hard drive that shows up on the boot screen . I'm hoping with help I can be able to do this myself without taking it into a shop.
