26 * In the SCSI world "SMART" is a dead or withdrawn standard. In recent
27 * SCSI standards (since SCSI-3) it goes under the awkward name of
28 * "Informational Exceptions" ["IE" or "IEC" (with the "C" for "control")].
29 * The relevant information is spread around several SCSI draft
30 * standards available at http://www.t10.org . Reference is made in the
31 * code to the following acronyms:
32 * - SAM [SCSI Architectural model, versions 2 or 3]
33 * - SPC [SCSI Primary commands, versions 2 or 3]
34 * - SBC [SCSI Block commands, versions 2]
36 * Some SCSI disk vendors have snippets of "SMART" information in their
