Troubleshoot: Event ID: 157 Disk X has been surprise removed RRS feed

  • Question

  • The event viewer may display:  Event ID: 157  Disk 6 has been surprise removed.

    After checking the drive with chkdsk /r and HD tune, Crystal Disk, Sea Tools, etc what are the additional troubleshooting steps when all of these drive tests pass so that there are no longer any surprise removed.

    These errors are most often caused when something disrupts the system’s communication with a disk, such as a SAN fabric error or a SCSI bus problem.  The errors can also be caused by a disk that fails, or when a user unplugs a disk while the system is running.  An administrator that sees these errors needs to verify the heath of the disk subsystem.

    1) What is a SAN fabric error and how do you troubleshoot it?

    2) What is a SCSI bus problem and how do you troubleshoot it?

    3) How do you verify the health of the disk subsystem?
