Event ID 11 System Log - Disk

Found this in my Windows 7 Pro x64 computer:

 The first Critical Blacklist Event found: Event ID - 11 System log - Disk: The driver detected a controller error on \Device\Harddisk1\DR1.

This computer only has one hard drive C: which is showing up in Disk Manager as Disk 0.

Could this be caused by someone removing incorrectly a USB device?

Thanks in advance.

Could be as you suggest, but I would immediately get the Hardware test / Hard drive test applications from your computer manufacturer and test the hard drive for errors.

If the hard drive is fine, you can probably ignore the event given your assumption above.

please first restart the Widows computer and see if the same or similar system event shows again. Do not the restart time and check all events after that.

you may also try plugging In a USB drive and see what disk number is shown for that drive.
