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 a negative reliability condition. 13.39.1.11 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 nonvolatile 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. The Sector Count register shall be set to specify the feature to be enabled or disabled: Sector Count 00h 01h F8h F9h Feature Description Disable Automatic Off-line Disable Off-line Read Scanning Enable Automatic Off-line Enable Off-line Read Scanning A value of zero written by the host into the device's Sector Count register before issuing this subcommand shall cause the automatic off-line data collection feature to be disabled. Disabling this feature does not preclude the device from saving attribute values to nonvolatile memory during some other normal operation such as during a power-on, during a power-off sequence, or during an error recovery sequence. A value of one written by the host into the device's Sector Count register before issuing this subcommand shall cause the off-line read scanning feature to be disabled. The Device does not perform the off-line read scanning at the off-line data collection activities which is initiated by the S.M.A.R.T. Execute Off-line Immediate (Subcommand D4h) or automatically if the off-line read scanning feature is disabled. A value of F8h written by the host into the device's Sector Count register before issuing this subcommand shall cause the automatic Off-line data collection feature to be enabled. A value of F9 written by the host into the device's Sector Count register before issuing this subcommand shall cause the off-line read scanning feature to be enabled. The Device perform the off-line read scanning at the off-line data collection activities which is initiated by the S.M.A.R.T. Execute Off-line Immediate (Subcommand D4h) even if the automatic off-line feature is disabled. Any other non-zero value written by the host into this register before issuing this subcommand is vendor specific and will not change the current Automatic Off-Line Data Collection and Off-line Read Scanning status. However, the device may respond with the error code specified in Table 129: "S.M.A.R.T. Error Codes" on page 185. Travelstar 5K100 Hard Disk Drive Specification 173

If the device does not detect a Threshold Exceeded Condition, or detects a Threshold Exceeded Condition but

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 a

13.39.1.11

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 nonvolatile 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 dis-

abled. This subcommand also enables and disables the off-line read scanning feature that cause the device to per-

form the entire read scanning with defect reallocation as the part of the off-line data collection activities.

The Sector Count register shall be set to specify the feature to be enabled or disabled:

A value of zero written by the host into the device's Sector Count register before issuing this subcommand shall

cause the automatic off-line data collection feature to be disabled. Disabling this feature does not preclude the

device from saving attribute values to nonvolatile memory during some other normal operation such as during a

power-on, during a power-off sequence, or during an error recovery sequence.

A value of one written by the host into the device's Sector Count register before issuing this subcommand shall

cause the off-line read scanning feature to be disabled. The Device does not perform the off-line read scanning at

the off-line data collection activities which is initiated by the S.M.A.R.T. Execute Off-line Immediate (Subcom-

mand D4h) or automatically if the off-line read scanning feature is disabled.

A value of F8h written by the host into the device's Sector Count register before issuing this subcommand shall

cause the automatic Off-line data collection feature to be enabled.

A value of F9 written by the host into the device's Sector Count register before issuing this subcommand shall

cause the off-line read scanning feature to be enabled. The Device perform the off-line read scanning at the off-line

data collection activities which is initiated by the S.M.A.R.T. Execute Off-line Immediate (Subcommand D4h)

even if the automatic off-line feature is disabled.

Any other non-zero value written by the host into this register before issuing this subcommand is vendor specific

and will not change the current Automatic Off-Line Data Collection and Off-line Read Scanning status. However,

the device may respond with the error code specified in Table 129: “S.M.A.R.T. Error Codes” on page 185.
