UNACCEPTABLE! UNACCEPTABLE!
Never install PC board on the Top!
The drive may be mounted horizontally with the PC board down or on
either side. Mounting vertically on either end is a prohibited orien-
tation. The drive should not be tilted front or back, in any posi-
tion, by more than 5*.
For optimum performance, the drive should be formatted
in the same position as it will be mounted in the host system.
The mounting screws must not exceed inside the mounting feet more
than 3.2 mm, measured from the outside surface of the foot.
Shock and vibrations
--------------------
All shock and vibration specifications assume that the drive is moun-
ted in an approved orientation with the input levels at the drive
mounting screws.
Shipping zone
-------------
Upon power-down, the read/write heads automatically move to the ship-
ping zone. All portions of the Head/slider assembly park inboard of
the maximum data cylinder.
When power is applied, the heads will recalibrate to Track 0.
FCC Verification
----------------
These drives are devices which are intended to be contained solely
within a personal computer or similar enclosure and not attached to
an external device. As such, they are considered to be subassemblies
even when individually marketed to the customer. As a subassembly, no
Federal Communications Commission authorization, verification or
certification of the device is required.
Disc format
-----------
The drives disc format is flexible and supports either 256, 512 or
1024 bytes/sector.
ST177N | ST1096N
----------------------------------------+--------------------
Bytes per Sector: 256 512 1.024 | 256 512 1.024
Sectors per Track: 44 26 13 | 44 26 13
Cylinders: 921 | 906
Read/Write heads: 5 | 7
Capacity (MByte): 52 61 60 | 71 84 83
Record interleave
-----------------
User-specific record interleaves are supported from 1:1 (sectors
occur sequentially on the disk) through the number of sectors per
track minus 1. This gives the user the ability to configure the drive
for maximum performance within the individual host operating environ-
ment.
Formatting and defect management
--------------------------------
Media defects are identified and recorded on the disc during the ma-
nufacturing process. This defect map is used during formatting and
enables the drive to bypass these defects. During the formatting
operation, the controller uses the sector-slip technique to reassign
defect sectors.
SCSI Interface
--------------
The embedded controller supports the SCSI interface as defined in the
ANSI X3T9.2/82-2 document. The interface hardware is capable of
transferring up to 12 Mbits/sec. using asynchronous data transfer.
Devices on the SCSI Interface are daisy-chained together using a
common cable. Both ends of the cable are terminated. All signals on
the interface are common between devices.
Termination resistor packs
--------------------------
The termination resistor packs must be present on devices at both
ends of the SCSI bus. All other devices should have the termination
resistors removed.
Termination resistors prevent signal reflections from the ends of the
SCSI bus, and assure proper bus timing.
DC Power specifications ----------------------- ST1096N only: The +12V must be supplied with 2 seconds of the +5 Volts. (If the +12V are applied more than 2 sec. after the +5V, the drive will boot but report read data errors.) The +12V and +5V power must be removed simultaneousely. ST1144 family drives: Power may be applied or removed in any sequence without loss of data or damage to the drive, except during a write operation. Typical current and power specifications assume nominal voltages applied, 25*C ambient temperature, sea level and spindle rotating. Voltage tolerance (incl. ripple): 5%
Input Noise ----------- Maximum permitted input noise ripple: 100 mV (peak-to-peak) Maximum permitted input noise: 20 MHz. Ripple measured at the host system power supply across an equivalent 8 resistive load on the +12 V line and an equivalent 3 load on the +5 V line.
Cable specification
-------------------
A 50-conductor flat cable or 25-conductor twisted pair cable is
required. The maximum cable length is 6 meters (19.7 ft). Each SCSI
bus connection may have a 0.1 meter (0.33 ft) maximum stub length.
The characteristic impedance for unshielded flat or twisted pair
ribbon cable should be 100 10%. A characteristic impedance greater
than 90 is preferred for shielded cables.
To minimize discontinuities and signal reflections it is desirable
to minimize the use of cables of different impedances in the same
bus.
Startup Drive Diagnostics
-------------------------
At power-on the drive will execute a series of diagnostic tests. Any
failure will be indicated by a series of LED (front panel) flashes.
The first failure will be preserved. The drive is ready to read/write
if no error codes are received within 22 seconds.

Offline Self-test Routines
--------------------------
This product family supports a self-test routine that Seagate recom-
mends for incoming inspection. This test may be run after the unit
has successfully passed the power-on diagnostics.
To enable the test, short the following pins to ground at the SCSI
connector: 2, 12, 16 and 32.
The self test has three parts. They will cycle in order until power
or a ground jumper is removed, or until ten complete passes.
The LED will remain ON during the test and will turn OFF if an error
is detected or a jumper is removed. The LED will flash continuously
if 10 passes are completed without error.
PART ONE: All sectors in the user data area are read starting with
logical block zero.
PART TWO: This is a butterfly read/seek test. Starting at the center
of the user data tracks, the unit will seek outward and inward by in-
crements until the limits of the user data tracks are reached. A one
track read is performed to verify position.
PART THREE: This part performs a write/read compare on all sectors of
the diagnostic cylinders using the data pattern 6DBh.
The diagnostic cylinders are located at an inner region on each media
surface. Any unrecoverable errors will terminate the test and turn
off the LED.

Access Time Definition and Timing
---------------------------------
Access time is a true statistical average (at least 5,000 measure-
ments) of the time to execute the seek, less overhead.
All measurements assume a block size of 512 bytes, nominal voltages,
25*C ambient temperature and sea level.
Track-to-track access time is the average of all possible single-
track seeks in both directions. Average access time is measured by
executing seek in both directions between random cylinders or Logi-
cal Block Addresses (LBA). Full-stroke access time is one-half the
time needed to seek from LBA zero to the maximum LBA and back to LBA
zero.
Note: Host overhead varies between systems and cannot be specified.
Drive internal overhead is measured by issuing a no-motion seek
from the highest Logical Block Address. Overhead is typically
less than 2 msec.
