Byte 5 The head offset count is not implemented. Head offsets
are performed as part of the drive’s retry algorithms.
Byte 6 The
data strobe offset count is not implemented.
Byte 7 Reserved.
Byte 8 The
write retry count field contains the maximum number
of times the drive attempts its recovery algorithms. If the
EER bit is set, the number of retries specified by the retry
count, up to a maximum of nine retries, is performed
before ECC is applied. The write retry count field has a
range of 0 through 20
H
. A write retry count of 0 means
that no retries are performed.
Byte 9 Reserved.
Bytes 10–11 The
recovery time limit field always has a value of FFFF
H
,
which means that the recovery time is unlimited.
