IBM DTTA-350320, Технические характеристики, Страница: 161 / 188

Bits 0 thru 6 represents a hexadecimal status value reported by the device.
Value Definition
0 Off-line data collection never started
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
12.31.2.4 Total Segments Required for Off-line Data Collection
The device will return 01h as the total segments for off-line data collection.
12.31.2.5 Total Time in Seconds to Complete Off-line Data Collection Activity
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).
12.31.2.6 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.
12.31.2.7 Off-Line Data Collection Capability
The device returns 05h as its off-line data collection capability which indicates: the Execute Off-Line Data
Collection Immediate is implemented; the device will abort all off-line activity if interrupted by a new
command.
12.31.2.8 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 indi-
cating 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 A T T R I B U T E 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 A T T R I B U T E AUTOSAVE
command.
