Symptoms

On a computer that is running Windows 7 or Windows Server 2008 R2, you receive the following Stop error message:

0x000000D1 (parameter1, parameter2, parameter3, parameter4)DRIVER_IRQL_NOT_LESS_OR_EQUAL

Notes

  • The parameters in this error message vary, depending on the configuration of the computer.

  • Not all "0x000000D1" Stop errors are caused by this issue.

This issue occurs after you enable a data digest for a cyclic redundancy check (CRC) function or for a checksum function on an iSCSI Initiator that is used on the computer.

Cause

This issue occurs because the iSCSI Initiator incorrectly processes sense data from a device after it receives a nonfatal check condition when iSCSI data digest verification is enabled. This issue usually occurs when tape devices or other non-fixed-disk SCSI devices are used.
