7.3.1.7 S.M.A.R.T. Read Log Sector (subcommand D5h)
This command returns the indicated log sector contents to the host. Sector count sepcifies the number of sectors to be read from the specified
log. The log transfferred by the drive shall start at the first sector in the speicified log, regardless of the sector count requested. Sector nubmer
indicates the log sector to be returned as described in the following Table.
7.3.1.8 S.M.A.R.T. Write Log Sector (subcommand D6h)
This command writes 512 bytes of data to the specified log sector. The 512 bytes of data are transferred at a command and the LBA Low
value shall be set to one. The LBA Low shall be set to specify the log sector address. If a Rea Only log sector is specified, the device returns
ABRT error.
7.3.1.9 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 subcom-
mand, 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.
7.3.1.10 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 auto save 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 auto saving.
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 Table 7-9: “S.M.A.R.T. Error Codes” on page 30.
Any Attribute Values accumulated and saved to volatile memory prior to receipt of the S.M.A.R.T. Disable Operations command will be pre-
served 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 a S.M.A.R.T. Save Attribute Values command.

RO - Log is read only by the host.
R/W - Log is read or written by the host.
VS - Log is vendor specific thus read/write ability is vendor specific.
