Recoverable Data Error Rate
Less
than
ten (10) errors in
10
13
bits transferred when the disk drive
is
operated within the
specified environmental limits.
Note: A recoverable
data
error occurs when a read or write operation sucessfully completes
with the execution of a recovery algorithm. The recovery action is reported
to
the host with a
Sense
Key
of
1.
(Refer to the Request Sense command in Appendix A.) Mode pages must be in
the factory default states.
Unrecoverable Data Error Rate
Less
than
ten (10) errors in
10
15
bits transferred when the disk drive is operated within the
specified environmental limits.
Note: An un-recoverable
data
error occurs when a read or write operation does not sucessfully
complete with the execution of a recovery algorithm. The unsuccessful operation is reported to
the host with a
Sense
Key
of
3.
(Refer to the Request Sense command in Appendix A.) Mode
pages
must be in the factory default states.
Seek Error Rate
Less
than ten (10) seek errors in
10
7
seeks when the drive
is
operated within the specified
environmental limits.
Note: A
seek
error occurs when the drive does not successfully locate the desired cylinder and
head.
Recording Density
Bit Density:
