GENERAL DESCRIPTION
REV.
A
3.1 Product Overview
The 7957B, 7958B, and 7959B
disc
drives
are
high
performance,
random
access,
fixed
media mass
storage
devices.
They
are
packaged
in
a compact
130mm
high
"Rosebud"
style
desktop
cabinet
that
looks
identical
to
the
7941/45.
Formatted
capacities
are
81,
152,
and 304
megabytes,
respectively.
Seek
times
less
than
18 msec,
full
HPIB
bandwidth
data
transfer
rate,
and
a
high
performance
HPIB
controller
combine
to
yield
performance
that
will
meet
or
exceed
791X
levels.
In
addition,
the
drives
will
be
extremely
rugged,
with
unsurpassed
shock,
vibration,
and
temperature
performance.
Factory
cost
at
introduction
will
be
under
$1800
for
the
7959B,
under
$1700
for
the
7958B, and
under
$1600
for
the
7957B.
It
is
expected
that
this
combination
of
mid-range
capacity,
low
cost,
high
performance,
and compact
size
will
quickly
make
the
795XB
the
preferred
choice
over
today's
7941/45
and 7912/14
products.
The
drives
are
based
on
Hewlett-Packard
designed
and
built
disc
mechanisms.
The 7959B
uses
the
HP
97536A mechanism,
while
the
7958B
uses
the
HP
97533A,
and
the
7957B
uses
the
HP
97532A.
All
mechanisms
use
5.25"
thin
film
media
with
thin
film
read/write
heads.
Each
has
a
rotary
actuator
with
one
head
per
surface,
and
all
use
embedded
servo
on
each
surface.
The
interface
to
the
mechanism conforms
to
the
ESDI
industry
standard.
The
795XB
series
have
four
major
sub-assemblies:
the
disc
mechanism,
HPIB
Controller
peA, power
supply,
and
cabinet
(with
associated
cables,
etc.)
The
standard
configuration
for
this
product
is
the
desktop
package.
The
desktop
unit
can
also
be
installed
into
any
floor
mount "pod"
style
cabinets
that
accept
"Rosebud"
stack-modules
(the
feet
must
be
removed from
the
drive
package
in
this
case).
The
drives
can
also
be
installed
in
19" EIA
racks
using
the
19500B Rackmount
Kit.

THIS
ISSUE
The
795XB
disc
controller
can
execute
special
utility
programs
contained
in
controller
firmware.
Among
other
functions,
these
utilities
perform
special
error
rate
tests.
The
internal
error
rate
tests
can
only
be
initiated
by a
diagnostic
program
running
on a
host
computer,
and
are
not
accessible
by a
user
interacting
through
a
standard
HP
file
system.
The
error
rate
tests
are
intended
to
be
used
for
diagnostic
purposes,
and
hence
report
more
detailed
information
than
would
be
supplied
under
file
system
access.
Much
of
this
detailed
"error"
information
is
not
indicative
of
impaired
storage
or
retrieval
capabilities,
but
is
monitored
in
the
factory
for
process
control
purposes.
Many
of
these
"errors"
would
never
be
seen
by
a
user
or
operator
running
under
file
system
control.
As
a
result,
the
recoverable
data
error
rate
allowed
when
running
these
tests
is
slightly
higher
than
that
allowed
under

The
products
also
have
a media

option
to
the
service
contract.
This
option,
R01,
allows
customers
with
sensitive
data
to
keep
their
HDA
upon
failure.
10.2 Mean Time to
Repair
(MTTR)
Since
the
drive
has
only
three
field
replaceable
assemblies
and
has
extensive
diagnostic
tools,
the
mean
time
to
repair
has
been
estimated
at
1/2
hour.
This
figure
is
based
on
the
assumption
that
the
CE
has
been
trained
on
the
product
and
has
a
working
knowledge
of
the
diagnostic
tools.
10.3 Preventive Maintenance Cycle
There
are
no
operating
or
maintenance
adjustments
on
the
795XB
Disc
Drives.
Therefore,
an
annual
PM
is
not
required.

10.4 Special Service
Features
Because
of
their
nature,
disc
drives
continue
to
develop
media
defects
throughout
their
useful
life.
As
a
result,
the
local
CE
is
called
out
in
many
cases
to
spare
out
thsse
defects.
The
195XB
disc
drives
include
a
special
feature
intended
to
greatly
reduce
this
type
of
service
call.
This
new
feature,
called
autosparing,
allows
the
disc
drive
to
automatically
spare
out
any
marginal
or
unrecoverable
media
defects
occurring
during
normal
operation.
Although
normally
available,
this
feature
may
be
deselected
by
the
host
during
the
"Set
Options"
command.
A
further
enhancement
of
the
autosparing
feature
provides
the
user
with
the
capability
to
initialize
media
and
spare
defects
offline.
This
additional
feature
may
be
invoked
by
selecting
unused
positions
of
the
HPIB
thumbwhee1
and
then
powering
up
the
drive.
The
drives
have
an
extensive
power-on
self-test
that
tests
the
general
functionality
of
the
mechanism,
the
controller
PCA,
and
the
ESDI
interface
linking
them.
Pass/fail
results
are
displayed
on
the
two
LEDs
on
the
disc
drive's
front
panel.
See
Section
12.3
for
an
LED
state
table.
System
diagnostic
capabilities
include
support
on
the
following
utilities:
HP1000:
HP3000:
HP85:
EXER
cs80
UTIL
EX795X
The
drives
are
also
supported
on
the
Response
Center's
Predictive
Support
program.
If
a
customer
opts
for
this
capability,
the
drives'
logs
are
monitored
periodically
to
ensure
that
predetermined
threshold
values
for
faults
and
data
errors
have
not
been
exceeded.
If
a
threshold
is
exceeded,
a
service
call
is
generated.
The
195XB
drives
that
are
on
HP3000
systems
also
have
the
capability
for
Remote
Support
from
the
Response
Centers.
This
program
gives
the
Response
Centers
the
ability
to
access
systems
remotely
and
perform
diagnostics
on
the
disc
drive,
thus
possibly
preventing
a
service
call.
If,
in
the
troubleshooting
process
the
CE
needs
to
verify
that
the
mechanism
is
bad,
cables
Wl
and
W3
are
long
enough
to
allow
a
replacement
mechanism
to
be
tested
without
removing
the
suspect
mechanism from
the
cabinet.
This
feature
saves
time
for
the
CE
by
making
troubleshooting
easier
and
more
efficient.
