Appendix C. Sense Data When a drive encounters an error, it makes sense data available. You can use device drivers to examine the sense data and determine errors. The device drivers may conflict with some commercial software applications unless properly configured. To avoid conflicts on Windows operating systems, refer to your device driver's procedures for setting the driver to manual startup mode. If your application uses other device drivers, see the appropriate documentation for those drivers to obtain the sense data. In addition to device drivers, other methods exist for obtaining sense data and error information. The sections that follow describe alternatives for gathering such information. Library Sense Data The following table lists the Additional Sense Codes (ASC) and Additional Sense Code Qualifiers (ASCQ) associated with the reported Sense Keys. A sense key of 00h (no sense) has no ASC/ASCQ associated with it. A few ASC/ASCQs can be associated with more than one sense key. The sense keys that can give a particular ASC/ASCQ are indicated within the Sense Key column. ASC/ASCQs that can indicate an abnormal element state as part of element descriptor. Table C-1.
