3 Off-line Read Scanning implemented bit 0 The device does not support Off-line Read Scanning 1 The device supports Off-line Read Scanning 4 Self-test implemented bit 0 Self-test routing is not implemented 1 Self-test routine is implemented 5-7 Reserved (0) 6 Selective self-test routine is not implemented 0 Selective self-test routine is not implemented 1 Selective self-test routine is implemented 12.42.2.7 S.M.A.R.T. Capability This word of bit flags describes the S.M.A.R.T. capabilities of the device. The device will return 03h indicating that the device will save its Attribute Values prior to going into a power saving mode and supports the S.M.A.R.T. ENABLE/DISABLE ATTRIBUTE AUTOSAVE command. Bit Definition 0 Pre-power mode attribute saving capability. If bit = 1, the device will save its Attribute Values prior to going into a power saving mode (Standby or Sleep mode). 1 Attribute Autosave capability. If bit = 1, the device supports the S.M.A.R.T. ENABLE/ DISABLE ATTRIBUTE AUTOSAVE command. 2-15 Reserved (0) 12.42.2.8 Error logging capability Bit Definition 7-1 Reserved (0) 0 The Error Logging support bit. If bit = 1, the device supports the Error Logging 12.42.2.9 Self-test failure check point This byte indicates the section of self-test where the device detected a failure. 12.42.2.10 Self-test completion time These bytes are the minimum time in minutes to complete the self-test. 12.42.2.11 Data Structure Checksum The Data Structure Checksum is the 2's complement of the result of a simple 8-bit addition of the first 511 bytes in the data structure. 12.42.3 Device Attribute Thresholds data structure The following defines the 512 bytes that make up the Attribute Threshold information. This data structure is accessed by the host in its entirety using the S.M.A.R.T. Read Attribute Thresholds. All multibyte fields shown in these data structures are in byte ordering, that is, that the least significant byte occupies the lowest numbered byte address location in the field.
