[Tim (PassMark)]

This error is logged when BurnInTest has requested the disk the seek to a specific location in the test file and the actual seek call by the device driver has failed to seek to that requested location.

If you turn on activity trace level 2, and only run the disk test to cut down on the amount of information logged, more information about the specific seek location should be logged so you can check if it is happening at the same or similar location each time.
