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.
