5.1.2.1 Off-line Mode
MSATA SSD’s support the optional 28-bit S.M.A.R.T. EXECUTION OFF-LINE
IMMEDIATE (B0h/D4h) command per the ATA-8 specification. This command
causes the MSATA SSD to initiate the collection of S.M.A.R.T. data in an off-line
mode and then preserves this data across power and reset events. Supported
subcommands include those shown in the table below. Reference the ATA-8
specification for subcommand detail.

Subcommands
Value Description
00h Execute S.M.A.R.T. off-line routine immediately in off-line mode
01h Execute S.M.A.R.T. Short self-test routine immediately in off-line mode
02h Execute S.M.A.R.T. Extended self-test routine immediately in off-line mode
04h Execute S.M.A.R.T. Selective self-test routine immediately in off-line mode
7Fh Abort off-line mode self-test routine
81h Execute S.M.A.R.T. Short self-test routine immediately in captive mode
82h Execute S.M.A.R.T. Extended self-test routine immediately in captive
mode
84h Execute S.M.A.R.T. Selective self-test routine immediately in captive mode
5.1.2.2 Captive Mode
When executing a self-test in captive mode, MSATA SSD’s execute the self-test
routine after receipt of the command. At the end of the routine MSATA SSD’s
place the results of this routine in the self-test execution status byte and reports
command completion. If an error occurs while the MSATA SSD is performing the
routine it discontinues its testing, place the results of this routine in the self-test
execution status byte and the DST log page, and complete the command.
5.1.2.3 S.M.A.R.T. Logs
S.M.A.R.T. logs are intended to enhance S.M.A.R.T. Attribute information by
capturing additional drive details at appropriate times. This information may lead
to improved error detection and reporting capability. The controller supports
S.M.A.R.T. logs, and relevant tests, events, and conditions each have an
associated log. S.M.A.R.T. logs conform to industry-standard structures.
The reported size of each log is reported by the Log Directory (Log 0). Note that
the information returned via S.M.A.R.T. Read Log access to Log 0 is more limited
than that via GP Read Log. Log size is only reported the LSB (max 255 blocks)
