Okay so I have a pc I built myself, I'm running Windows 7 64-bit. The problem I'm having is I have a secondary drive, used only for storage of photos, music, movies, etc. The model is a Western Digital WDC WD10EARS-00Y5B1 (SATA) It recently completely crashed on start up and deleted unreadable/bad sectors deleting everything on the drive all the way to the point where I reformatted it because it wasn't even shown as an available drive. Once I did that it seems to be functioning fine (even though none of my 500+ gigs of stuff is there.) I ran a WD diagnostic tool which says everything on the drive is fine but one test says there are still unrepairable sectors. What do I do? Do I just need a new drive because it seems to be functioning now and the smart disk info is green checks all across the board.
