If there is a S.M.A.R.T. error, there is not much chance the drive will survive. If you get that error, back up immediately, because the drive is normally gone or very near dying. For the error you are seeing on the other drive, I would suggest that you try to format it using one of the following two programs.
Dban
Kill Disk
These programs do take quite a bit of time, but they clean the disk much more than any format will. When the drive is done, it will be back to factory specs and completely clean. Be sure you do not erase any other drive on the computer while running either of these programs, so I suggest you remove all other hard disks while running either of these programs.
Please understand, if you use one of these programs, you lose ALL information and data from that disk.
