27 | * In the SCSI world "SMART" is a dead or withdrawn standard.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