13.38.1.5 S.M.A.R.T. Execute Off-line Immediate (subcommand D4h) This subcommand causes the device to immediately initiate the set of activities that collect Attribute data in an offline mode (off-line routine) or execute a self-test routine in either captive or off-line mode. The LBA Low register shall be set to specify the operation to be executed. LBA Low 0 1 2 127 129 130 Operation to be executed Execute S.M.A.R.T. off-line data collection routine immediately Execute S.M.A.R.T.

Short self-test routine immediately in captive mode Execute S.M.A.R.T. Extended self-test routine immediately in captive mode Off-line mode: The device executes command completion before executing the specified routine. During execution of the routine the device will not set BSY nor clear DRDY. If the device is in the process of performing its routine and is interrupted by a new command from the host, the device will abort or suspend its routine and service the host within two seconds after receipt of the new command. After servicing the interrupting command, the device will resume its routine automatically or not start its routine depending on the interrupting command. Captive mode: When executing self-test in captive mode, the device sets BSY to one and executes the specified self-test routine after receipt of the command. At the end of the routine, the device sets the execution result in the Self-test execution status byte (see Table 113: "Device Attribute Data Structure" on page 166) and ATA registers-see definitions below-and then executes the command completion.

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 (See Table 112: "S.M.A.R.T. Function Set (B0h)" on page 161). If a Read Only log sector is specified, the device returns ABRT error. 13.38.1.8 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.

13.38.1.5

S.M.A.R.T. Execute Off-line Immediate (subcommand D4h)

This subcommand causes the device to immediately initiate the set of activities that collect Attribute data in an off-

line mode (off-line routine) or execute a self-test routine in either captive or off-line mode. The LBA Low register

shall be set to specify the operation to be executed.

Off-line mode:

The device executes command completion before executing the specified routine. During execu-

tion of the routine the device will not set BSY nor clear DRDY. If the device is in the process of performing its rou-

tine and is interrupted by a new command from the host, the device will abort or suspend its routine and service the

host within two seconds after receipt of the new command. After servicing the interrupting command, the device

will resume its routine automatically or not start its routine depending on the interrupting command.

Captive mode:

When executing self-test in captive mode, the device sets BSY to one and executes the specified

self-test routine after receipt of the command. At the end of the routine, the device sets the execution result in the

Self-test execution status byte (see Table 113: “Device Attribute Data Structure” on page 166) and ATA regis-

ters—see definitions below—and then executes the command completion.

13.38.1.6

S.M.A.R.T. Read Log Sector (subcommand D5h)

This command returns the specified log sector contents to the host.

The 512 bytes of data are returned 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.

13.38.1.7

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 com-

mand and the LBA Low value shall be set to one. The LBA Low shall be set to specify the log sector address (See

Table 112: “S.M.A.R.T. Function Set (B0h)” on page 161). If a Read Only log sector is specified, the device

returns ABRT error.

13.38.1.8

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
