Event ID 11 error

In my Windows 7 computer, I'm getting the following error...
The driver detected a controller error on \Device\Harddisk3\DR3.

I have ( C: ) two SSD drives in RAID configuration, one ( D: ) internal HDD, and one ( F: ) external HDD.
Which one does the \Device\Harddisk3\DR3 refer to or is it referring to something else?
Is this referring to a bad driver, controller, or HDD?


Thanks...

EDIT: could this be in reference to the floppy ( A: ) drive that the system sees but that doesn't exist?

  1. Best answer
    The 2 drives in RAID, or your boot drives are referred to as drive 0 and drive 1.
    Most likely, the internal drive is 2 and the external drive is 3.

    It might have something to do with the floppy drive not being there, maybe. Doubtful but maybe. Why don't you turn the floppy drive seek off in the BIOS if you don't have one?
  2. I've adjusted the BIOS as you suggested and so far so good.
    Let's give it a few days to see if it rears its ugly head again.
  3. Check disk numbers in Control Panel->Disk management. Not the same as the bios numbers.
    Run manufacturer hard disk diagnostics.
    Any jumpers on SATA drives?
