milliseconds
The
drive meets recoverable
and
unrecoverable
data
error
rate
specifications (refer
to
Table
1-2)
with
no recoverable
or
unrecoverable hardware faults. Mode pages must
be
in
factory

The
drive meets unrecoverable

with
no
unrecoverable hardware faults. Mode pages
must
be
in factory default

Nonoperating:
Applied Acceleration
(half
sine)
................................
50 g (peak),
11
milliseconds
The
drive meets recoverable
and
unrecoverable
data
error
rate
specifications (refer
to
Table
1-2) with no recoverable
or
unrecoverable
hardware
faults
and
no
damage
to
the
mechanism.
Mode pages
must
be
in
factory default
state.
Notes:
A recoverable
hardware
fault
occurs when the drive detects a
hardware
error, such
as
a seek
or
track
following error,
and
successfully completes the
operation
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.
An un-recoverable hardware
fault
occurs when
the
drive
detects
a
hardware
error, such as a
seek
or
track
following error,
and
does
not
successfully complete
the
operation
with
the
execution
of
a recovery algorithm.
The
unsuccessful
operation
is
reported
to
the
host with a
Sense Key
of
4.
(Refer
to
the
Request Sense
command
in
Appendix
A.) Mode pages
must
be
in
the
factory default
states.
