Deciphering Event ID 11: What does Harddisk3 and DR4 refer to? RRS feed

  • Question

  • Hi. I often get this event in my event logs and I have several questions regarding it:

    The driver detected a controller error on \Device\Harddisk3\DR4
    Event ID: 11
    Source: Disk

    Question 1: What does Harddisk3 refer to? (i.e. Does it refer to a disk, partition, volume or something else? Do we have Harddisk0 too? etc.)

    Question 2: What does DR4 refer to? (i.e. Does it refer to a disk, partition, volume, or something else? Do we have DR0 too? etc.)

    Question 3: How do these information possibly apply to my system? I have one hard disk with only one partition on it. I have a DVD drive and I occasionally connect a USB flash disk.

  • Well, I guess I am making progress in finding out. Having visited Winobj.exe multiple times, it seems that I always have \Device\Harddisk0\DR0, which refers to my physical hard disk. But when I connect a USB flash drive for the first time in each session, I get a \Device\Harddisk1\DR1. Now, if I eject the device, naturally I no longer have \Device\Harddisk1\DR1. But if I reconnect the device, I get a \Device\Harddisk1\DR2. If I eject and connect another USB flash device, I will have \Device\Harddisk1\DR3, with no sign of DR2 or DR1.

    So, in case of the log entry which I am looking at, the error has occurred on the fourth  physical storage device, that I had connected to my computer, designated Harddisk3. (Bear in mind that the count start from zero, not one.) However, DR4 means that at one occasion during the session, I had ejected one storage device and connected another.

    These are all assumptions made based on experiments and may not be correct at all; maybe I have not accounted for something. Still, I guess I have my answer.

  • That's an object name.  Maybe sysinternals winobj can help?  Maybe you have some hidden recovery partitions.

  • Thanks for the tip. Well, WinObj certainly did help get a better view of what is what but I can't say any of my questions are answered.

  • Hi,

     

    I would like to suggest you try to Diskpart Command-Line Utility to check if you have any disk3 information.

  • It would have been an excellent advice if I somehow had noticed when the event is triggered. Right now, Diskpart only shows one "Disk 0". But thank you for your advise.

    Still, what about DR4?

  • Is it in the 'GLOBAL??' folder in winobj?  I have all the drive letters in there.

    c:  symboliclink  \device\harddiskvolume3

    d:  symboliclink  \device\cdrom0

    t:  symboliclink  \device\thwdevice0

  • It is like this:

    \
    \ Device
     \ Harddisk0
      \ DR0
     \ Harddisk1
      \ DR1
    
    As you can see, "Harddisk0" and "Harddisk1" are subfolders of "Device". But "DR0" and "DR1" are items.
