06 DU
The Disable Update bit is always set to 0, indicating the drive
updates parameter values for all events.
DS
The Disable Save bit is always set to 1, indicating the drive
does not save parameter values.
TSD
The Target Save Disable bit is always set to 0 indicating the
drive defines a method for saving log parameters.
ETC
The Enable Threshold Comparison bit is always set to 0,
indicating comparison to the threshold value is not performed
whenever the cumulative value is updated.
TMC
The Threshold Met Criteria bits are used with the ETC bit and
are always set to 0.
LP
The List Parameters bit is always set to 0, indicating all
parameters are data counters.
07 Parameter Length
Set to 02h, indicating 2 bytes in the counter.
08-09 Total Re-Reads (*)
Total number of uncorrectable frames. An uncorrectable
frame will generate a Re-Read recovery sequence.
…
0E-10 Total Errors Corrected
(*)
Total number of frames corrected is the sum of the number of
frames corrected by ECC plus the number of frames corrected
by the Re-Read recovery procedure.
…
15-16 Frames Corrected By
ECC Alone (*)
The total number of frames containing one or more blocks that
failed the CRC check. For the total number of blocks, see
REQUEST SENSE.
…
1B-1F Total Bytes Processed
(*)
The transfer length of all Fixed Block Mode READ commands
times the block length specified in Mode Data plus the total
transfer length of all Variable Block Mode READ commands.
…
1B-1F Total Bytes Corrected
by ECC (*)
The total number of bytes corrected by ECC during all READ
commands.
