14.39.1.7 S.M.A.R.T. Write Log Sector (Subcommand D6h)
This command writes 512 bytes data to the specified log sector.
The 512 bytes data are transferred at a command and the Sector Count value shall be set to one. The LBA Low shall
be set to specify the log sector address (Figure 88). If Read Only log sector is specified, the device returns ABRT
error.
14.39.1.8 S.M.A.R.T. Enable Operations (Subcommand D8h)
This subcommand enables access to all S.M.A.R.T. capabilities within the device. Prior to receipt of a S.M.A.R.T.
Enable Operations subcommand, Attribute Values are neither monitored nor saved by the device. The state of
S.M.A.R.T. (either enabled or disabled) will be preserved by the device across power cycles. Once enabled, the
receipt of subsequent S.M.A.R.T. Enable Operations subcommands will not affect any of the Attribute Values.
Upon receipt of the S.M.A.R.T. Enable Operations subcommand from the host, the device asserts BSY, enables
S.M.A.R.T. capabilities and functions, clears BSY and asserts INTRQ.
14.39.1.9 S.M.A.R.T. Disable Operations (Subcommand D9h)
This subcommand disables all S.M.A.R.T. capabilities within the device including the device's attribute autosave
feature. After receipt of this subcommand the device disables all S.M.A.R.T. operations. Non self-preserved
Attribute Values will no longer be monitored. The state of S.M.A.R.T. (either enabled or disabled) is preserved by
the device across power cycles. Note that this subcommand does not preclude the device's power mode attribute
autosaving.
Upon receipt of the S.M.A.R.T. Disable Operations subcommand from the host, the device asserts BSY, disables
S.M.A.R.T. capabilities and functions, clears BSY and asserts INTRQ.
After receipt of the device of the S.M.A.R.T. Disable Operations subcommand from the host, all other S.M.A.R.T.
subcommands -- with the exception of S.M.A.R.T. Enable Operations -- are disabled, and invalid and will be
aborted by the device (including the S.M.A.R.T. Disable Operations subcommand), returning the error code as
specified in "Figure 118 S.M.A.R.T. Error Codes" on page 164.
Any Attribute Values accumulated and saved to volatile memory prior to receipt of the S.M.A.R.T. Disable
Operations command will be preserved in the device's Attribute Data Sectors. If the device is re-enabled, these
Attribute Values will be updated, as needed, upon receipt of a S.M.A.R.T. Read Attribute Values or S.M.A.R.T.
Save Attribute Values command.
14.39.1.10 S.M.A.R.T. Return Status (Subcommand DAh)
This command is used to communicate the reliability status of the device to the host's request. Upon receipt of the
S.M.A.R.T. Return Status subcommand the device asserts BSY, saves any updated Attribute Values to the reserved
sector and compares the updated Attribute Values to the Attribute Thresholds.
If the device does not detect a Threshold Exceeded Condition, or detects a Threshold Exceeded Condition but
involving attributes are advisory, the device loads 4Fh into the LBA Mid register, C2h into the LBA High register,
clears BSY, and asserts INTRQ.
If the device detects a Threshold Exceeded Condition for prefailure attributes, the device loads F4h into the LBA
Mid register, 2Ch into the LBA High register, clears BSY, and asserts INTRQ. Advisory attributes never result in
negative reliability condition.
14.39.1.11 S.M.A.R.T. Enable/Disable Automatic Off-Line (Subcommand DBh)
This subcommand enables and disables the optional feature that cause the device to perform the set of off-line data
collection activities that automatically collect attribute data in an off-line mode and then save this data to the
device's non-volatile memory. This subcommand may either cause the device to automatically initiate or resume
performance of its off-line data collection activities or cause the automatic off-line data collection feature to be
disabled. This subcommand also enables and disables the off-line read scanning feature that cause the device to
perform the entire read scanning with defect reallocation as the part of the off-line data collection activities.
