|A few thoughts:|
Does it show in Device Manager and/or Disk Management?
If it failed recently you could try System Restore (if you know approximately when).
Most likely the driver was part of XP so type sfc /scannow in the Run box. Let it run through and hope it finds and replaces the driver file.
Error messages are often MS near misses. It could be that the drive itself has failed.
Always pop back and let us know the outcome - thanks
