I'm randomly getting errors in the System Log about a "Controller error on \Device\Harddisk3\DR3"; this may be of course a driver error, a NTFS error, or, more seriously, a failing disk.

But I have various physical disks in my computer, and even some RAID volumes managed by the onboard Intel controller (which the OS sees as even other disks).

So: how can I map \Device\HarddiskX\DRX to the actual disk it's referring to?

  • Enumeration of hard disks should reflect firmware order starting from 0 (DR0) – snayob Oct 12 '12 at 17:53
  • But this tends to get quite messed up when more than one controller is involved. – Massimo Oct 12 '12 at 17:58
