Hello Friends,
As soon as any drive starts developing bad sectors, it's usually a sign of its impending demise (it's going to completely fail). Best advice is to get all the data off it as soon as you can, and transfer to a new drive.
I know that there are a lot of services to repair bad sectors on hard disks. But it's rather expensive and the guarantee that your data and soft will be recollected again fifty percent. So try to do it yourself trough defragmentation.
