any help??
So here is what some users do when they don't understand fully the problem, but they understand the risk. You go out and buy a new hard drive, something within your budget, maybe even a cheaper smaller drive. But something that works for sure.
Next install your operating system of choice on the new drive, without the old drive being present in the system. After you get everything up and running, you reboot with the old drive as a slave and transfer some of your most important documents, photos and videos and downloads to the new drive.
Then when you are satisfied that your new drive is working right, and apparently there is not any intrinsic problem with the software and the rest of your hardware, you make a decision. The decision is to just continue with the new installation, or put the old drive back in and play around and see if you can figure out what happened. If you fail, you have all your stuff on the new drive and a new install of your favorite operating system.
Perhaps that may seem very obvious, yet so many users believe that there is an easy quick fix to their problems without having a backup.
