1
Segment completed without error
2
All segments completed without errors. In this case, current segment pointer equals to total seg-
ments required.
5
Off-line data collecting aborted by interrupting command
6
Off-line data collection aborted with fatal error
12.29.2.4 Total Segments Required for Off-line Data Collection
The device will return 07h as the total segments for off-line data collection. The device divides its off-line
data collection activity into 7 segments. These segments consists of: segment 1 through 4 = raw read error
rate and throughput measurement, segment 5 =
1000 track to track seeks, segment 6 =
1000 1/3 stroke
seeks, and segment 7 = 1000 full stroke seeks.
12.29.2.5 Total Time in Seconds to Complete Next Segment
This field tells the host how many seconds the device requires to complete the segment pointed by the
current segment pointer. The host can use this time to set a count down timer that will trigger it to issue the
“SMART Read Attribute Values” subcommand to check on the status of off-line data collection. This field
indicates the total time in seconds for the first segment if the current segment pointer is 00h or the off-line
status indicates all segments completed (02h).
12.29.2.6 Current Segment Pointer
This byte is a counter indicating the next segment to execute as an off-line data collection activity. This
varies from 00h to the total number of segments. The current segment pointer will be 00h if the off-line data
collection has not been started. If the off-line data collection is aborted by a command or an error (i.e., the
status is 05h or 06h), this byte will point to the aborted segment. If the all segments complete, this byte will
equal to the total number of segments.
12.29.2.7 Off-Line Data Collection Capability
The device returns 05h as its off-line data collection capabillty which means:
Bit

0
Execute Off-line Immediate is implemented
1
Enable/Disable Automatic Off-line is N O T implemented
2
Abort/restart off-line by host
The device will abort all off-line data collection activity initiated by an S.M.A.R.T. Execute Off-
line Immediate subcommand upon receipt of a new command. Off-line data collection activity
must be restarted by a new S.M.A.R.T. Execute Off-line Immediate subcommand from the host.
