04h
Total Times Correction Algorithm Processed. This parameter code specifies the counter that
counts the total number of retries, or "times the retry algorithm is invoked." If after five attempts a
counter 02h type error is recovered, then five is added to this counter. If three retries are required
to get a stable ECC syndrome before a counter 01h type error is corrected, then those three
retries are also counted here. The number of retries applied to unsuccessfully recover an error
(counter 06h type error) are also counted by this counter.
05h
Total Bytes Processed. This parameter code specifies the counter that counts the total number of
bytes either successfully or unsuccessfully read, written, or verified (depending on the log page)
from the drive. If a transfer terminates early because of an unrecoverable error, only the logical
blocks up to and including the one with the unrecoverable error are counted.
06h
Total Uncorrected Errors. This parameter code specifies the counter that contains the total number
of blocks for which an uncorrected data error has occurred.

Parameter code 00h is the only code supported for this page and it represents the number of recoverable
error events other than write, read, or verify errors.

Parameter Code [1]
Notes.

Parameter codes 00h through 04h are described following:
00h
This parameter code represents the number of logical blocks that have been sent to an initiator.
01h
This parameter code represents the number of logical blocks that have been received from an initi-
ator.
02h
This parameter code represents the number of logical blocks read from the cache memory that
have been sent to an initiator.
03h
This parameter code represents the number of read and write commands that had data lengths
equal or less than the current segment size.
04h
This parameter code represents the number of read and write commands that had data lengths
greater that the current segment size.
