Fatal Error Solutions

The SCSI verifier has detected an error in...

STOP: 0x000000F1


The SCSI device driver has a bug that is only identified when the optional Driver Verifier is active.

Some older versions of Windows may show the description as "SCSI_VERIFIER_DETECTED_VIOLATION".

This is a fatal Windows error, typically called a Stop message, Bug Check, or more commonly the Blue Screen of Death (BSoD). The system is in a forced reboot state. Any unsaved work is likely lost.

  Sample Screen  

A problem has been detected and Windows has been shut down to prevent damage to your computer.

The SCSI verifier has detected an error in a SCSI Port/Storport miniport driver being verified.

If this is the first time you've seen this Stop error screen, restart your computer. If this screen appears again, follow these steps:

Check to make sure any new hardware or software is properly installed. If this is a new installation, ask your hardware or software manufacturer for any Windows updates you might need.

If problems continue, disable or remove any newly installed hardware or software. Disable BIOS memory options such as caching or shadowing. If you need to use Safe Mode to remove or disable components, restart your computer, press F8 to select Advanced Startup Options, and then select Safe Mode.

Install the latest Windows software updates. Don't forget to check for non-critical updates too!

To manually get updates, open Internet Explorer (you can't use a non-Microsoft browser for updates).

For IE 8 and later: Click on Safety, then Windows Update. Follow the instructions.


For IE 7 and older: Click on Tools, then Windows Update. Follow the instructions.

A SCSI Verification violation occured when running the Driver Verifier.

After the Stop code will be 4 hex values: {Parameter 1, Parameter 2, Parameter 3, Parameter 4}.

Parameter 1 specifies the cause of the issue.

0x00000000 The miniport driver passed bad arguments to ScsiPortInitialize.
0x00000001 The miniport driver called ScsiPortStallExecution and specified a delay greater than 1/10 second, stalling the processor too long.
0x00000002 A miniport routine called by the port driver took longer than a half a second to execute (half a second is the limit for most routines. However, the HwInitialize routine is allowed 5 seconds, and the FindAdapter routine is exempt.)
0x00000003 The miniport driver completed a request more than once.
0x00000004 The miniport driver completed a request with an invalid SRB status.
0x00000005 The miniport driver called ScsiPortNotification to ask for NextLuRequest, but an untagged request is still active.
0x00000006 The miniport driver passed an invalid virtual address to ScsiPortGetPhysicalAddress (This usually means the address supplied doesn't map to the common buffer area.)
0x00000007 The reset hold period for the bus ended, but the miniport driver still has outstanding requests.

Parameter 2 depends on the value of Parameter 1.

Parameter 3 depends on the value of Parameter 1.

Parameter 4 depends on the value of Parameter 1.
