Overview of SCSI Miniport Debugging

Small computer system interface (SCSI) debugging extensions can be found in two extension modules: Scsikd.dll and Minipkd.dll. For an overview of the most important extension commands in these modules, see Extensions for Debugging SCSI Miniport Drivers. For a complete list, see SCSI Miniport Extensions.

The SCSIkd.dll extension commands can be used in any version of Windows. The Minipkd.dll extension commands can only be used in Windows XP and later versions of Windows. Commands in Minipkd.dll are only applicable to miniport drivers that work with the SCSI Port driver.

To test a SCSI miniport driver, use the SCSI Verification feature of Driver Verifier. For information about Driver Verifier, see  Driver Verifier in the Windows Driver Kit (WDK) documentation.
