How to know \Device\Harddisk#\DR# is which physical hard disk?

How to know \Device\Harddisk#\DR# is which physical hard disk?

Under Windows environment, we are used to the drive letter such as C: or D: drive but the error in the Windows Event Viewer normally point out the faulty device in the different format \Device\?Harddisk#\DR# or \Device\HarddiskVolume# (e.g. \Device\Harddisk0\DR0). So, how can find/locate the correct hard disk / device?

Problem: The drive detected a controller error on \Device\Harddisk0\DR0

Below are the example of event log:

Log Name: System

Source: disk

Event ID: 11

Level: Error

General/detail: The drive detected a controller error on \Device\Harddisk0\DR0.

 

 

Solution: To find the error disk \Device\Harddisk0\DR0

  1. Download WinObj from https://technet.microsoft.com/en-us/library/bb896657.aspx
  2. Right-click on downloaded WinObj and run as administrator
  3. Search through \Device\Harddisk# until you find your faulty device (e.g. \DR0)
  4. You can see one or multiple Partition with SymbolicLink Type. (in my example, I got \Device\HarddiskVolume1 to 8 are belong to this device/disk). Note this down for the next step.

    WinObj \Device\Harddisk0

    \Device\Harddisk0

  5. Click on \GLOBAL?? in the left panel, then click on the "SymLink" column in the right panel in order to have the result sort in SymLink.
  6. Find / locate \Device\HarddiskVolume# value you found in the step #4
  7. You will notice that the name of the volume in the first column. There will be multiple entries that include volume GUID, drive letter, etc. From my result below, I can see that my C: drive is located in this \Device\Harddisk0\DR0 disk.WinObj \GLOBAL??
