QUANTUM PRODRIVE 120/170/210AT PRODUCT MANUAL
Jumper Setting
==============
x = Jumpers set at factory
DS Drive Select Jumper Option
------------------------------
x CLOSED Single drive or MASTER (Drive 0)
OPEN SLAVE (Drive 1)
Note: The order in which drives are connected in a daisy chain has no
significance.
You can daisy-chain two drives on the AT-bus interface. When daisy-
chaining two drives, configure one drive as the MASTER, the other as
the SLAVE, with the Drive Select (DS) jumper pins on the drives.
SP Slave Present Jumper Option
-------------------------------
The slave present jumper has two meaning, depending on the setting of
the DS jumper.
1) If the ProDrive 120/170/210AT hard disk drive is configured as a
MASTER (DS jumper installed), the SP jumper informs the drive of
the presence of a SLAVE drive. This jumper should only be
installed on the MASTER if the SLAVE drive does not use the Drive
Active Slave Present signal (pin 39) to indicate that it is
present.
2) If the ProDrive 120/170/210AT hard disk drive is configured as a
SLAVE (DS jumper is not installed), and the MASTER is a non-
Quantum drive, a jumper installed on the SP jumper pins puts the
ProDrive into a special slave mode. In this mode, the ProDrive
does not do hardware tests in the diagnostics command to avoid
taking too long to drive BUSY, resulting in making the operation
with another drive as fast as possible.
Quantum ships all ProDrive 120/170/210AT hard disk drives with no
jumper installed on the SP jumper pins.
SS Drive Mode Jumper Option
----------------------------
The drive mode jumper options maintains compatibility with the
ProDrive 40/80 AT hard disk drives. When a jumper is installed on the
SS jumper pins, the ProDrive 120/170/210AT hard disk drive is in a
ProDrive 40/80AT compatible mode as a master or as a slave depending
on the way the DS and SP jumpers are installed. This information
applies to all drive containing firmware version 1.05J or later.

+------+------+------+------+--------------------------------------+
Note: ProDrive 40/80AT mode always means that the drive select bit in
the AT interface chip is not reset to zero on diagnostics commands
OR soft resets, and that the 120/170/210AT drives do not check for
PDIAG.
Description of Configurations (from Table)
1. ProDrive 120/170/210AT master in the standard Command Access
Method (CAM) specification mode. ProDrive 120/170/210AT master
used DASP to check for slave and uses PDIAG to determine if the
slave passed power on, soft reset, and diagnostics. This is the
factory default setting.
2. ProDrive 120/170/210AT master in ProDrive 40/80AT mode. The code
looks at DASP to determine if a slave is present. If it sees DASP,
it assumes the other drive is a ProDrive 40/80AT and operates in
the ProDrive 40/80AT mode.
3. A ProDrive 120/170/210AT master with a non-Quantum slave. The
drive knows there is a slave by the SP jumper, and it does not
check DASP. It does check PDIAG at power on, soft reset, and
diagnostics. On the diagnostics command, the ProDrive
120/170/210AT skips the hardware tests, making operation with
another drive as fast as possible.
5. A ProDrive 120/170/210AT master with a ProDrive 40/80AT slave. The
code knows a slave is present, by the SP jumper, and does not
check DASP.
6. ProDrive 120/170/210AT slave in the standard CAM spec mode.
7. ProDrive 120/170/210AT slave with a ProDrive 40/80AT master.
8. The ProDrive 120/170/210AT is a slave, however, daisy-chained to a
non-Quantum drive. In this mode, the ProDrive 120/170/210AT does
not do hardware tests in the diagnostic command to avoid taking
too long to drop BUSY. This makes operation with another drive as
fast as possible.

---------------------------------------------------------------------
Adapter Board Jumper Options
============================
Four jumper pins on the adapter board - labeled J2 through J5 - have
the function described below.
J2 Enables the drive's interrupt logic to control INTRQ. This option
provides compatibility with systems in which the BIOS does not
read the STATUS register when the drive issues an interrupt to
the system.
- A jumper from the center pin J2 to E3 enables transmission of
an interrupt every time the drives goes busy.
- A jumper from the center pin J2 to E4 gates the interrupt from
the drive and transmits it directly to the AT bus. This is
factory default setting.
J3 These pins should always remain open, with no jumper installed.
J4 These pins should generally remain open. A jumper should be
installed on these pins only when installing the adapter board
in a system that uses the Chips & Technologies chip set. This
chip set runs the I/O bus faster than the standard 12 Mhz, one
wait state.
J5 Enables secondary interface selection on a second adapter board
installed in a system. When a jumper is installed on these pins,
drives connected to the adapter board respond to commands
transmitted via the secondary address, 170H-177H. Standard BIOSs
do not support secondary addresses. Therefore, the user must
write a custom driver to implement a secondary interface.
Note: A second adapter board is supported only when both adapter
boards are Quantum boards.

Notes on Installation
=====================
Mounting
--------
The ProDrive 120/170/210AT hard disk drive can be mounted in any
orientation. UNC 6-32 screws are recommended for mounting.

+-+-----------------+-+ +--+ +--+
| |
| |
+-----------------+
Note: With the exception of the faceplate and mounting brackets,
clearence between the drive and any other surface must be a minimum
of 0.10 inch.
Caution: The PCB is very close to the drive-mounting bracket. Do not
exceed the specified length for the mounting screws. The specified
screw length allows full use of the mounting-hole threads, while
avoiding damaging or placing unwanted stress on the PCB. To avoid
stripping the mounting-hole threads, the maximum torque applied to
the mounting screws must not exceed 8 inch-pounds.
Ventilation
-----------
The ProDrive 120/170/210AT hard disk drives operates without a
cooling fan, provided the ambient air temperature does not exceed
122*F (50*C). Any user-designed cabinet should provide adequate air
circulation to prevent the maximum temperature from beeing exceeded.
AT-Bus Interface Connector J1
-----------------------------
The ProDrive 120/170/210AT hard disk drive requires one AT-bus
interface cable connector.
Connection to J1 is through a 40-pin universal header connector.
Pin 20 has been removed to prevent incorrect installation of the
mating connector. The mating connector shoud have a keying plug
installed in pin position 20.
Note: To avoid plugging the connector backwards, unkeyed mating
connections should not be used.
Recommended part numbers for the mating connector:
40-pin connector, without strain relief AMP P/N 1-746185-0, or
equivalent
Strain relief for 40-pin connector AMP P/N 1-499252-1, or
equivalent
Keying Plug AMP P/N 86286-1, or
equivalent
DC Power Connector J3
---------------------
The DC power connector is a 4-pin Ranoda Electronics Connector
(06300010-04-1) mounted on the back edge of the Printed Circuit Board
(PCB).
Recommended part numbers for the mating connector are:
4-pin connector AMP P/N 1-480424-0 or equivalent
Loose-piece contacts AMP P/N 60619-4 or equivalent
Strip contacts AMP P/N 61117-4 or equivalent
Faceplate LED Operation
-----------------------
Whenever the drive initiates the execution of a command, a green LED
on the faceplate ligths, and remains lit until the execution of the
command is complete or aborted.
Air Filtration
--------------
ProDrive Series hard drives are Winchester-type drives. The heads fly
very close to the media surface, with a nominal flying height of less
than 10 microinches. Therefore, it is essential that the air
circulating within the drive be kept free of particles. Quantum
assembles the drive in a Class-100, purified air environment, then
seals the drive with a metal cover. When the drive is use, the
rotation of the disks forces the air inside the drive through an
internal filter.
Disk Format
-----------
The ProDrive 120/170/210AT hard disk drive has 1,127 cylinder, with
five tracks per cylinder in the 120AT, and seven tracks per cylinder
in the 170AT and 210AT. 1,123 cylinders are for user data, while four
are reserved for hard disk system use - including test-equipment
data, defect maps, and diagnostics - and form boundaries between the
data zones.
Electrical Characteristics
--------------------------
All signals are TTL-compatible - with logic one greater than 2.0
volts and less than 5.25 volts; and logic zero, greater than 0.0
volts and less than 0.7 volts. Neither the adapter board nor the
drives require terminating resistors.
--------------------------------------------------------------------
Adapter Board Installation
--------------------------
The adapter board is a half-size board and can be installed in any
available 16-bit slot in an IBM PC-AT or compatible. Before install-
ing the adapter board, make sure that no other hard disk drive
controller resides at the primary drive address, 1F0H-1F7H.
- On a Western Digital WD1002-WA2 or WD1003-WA2 floppy/hard drive
controller card:
1. Do not install jumpers on pins E5 and E6 and install jumpers on
Pins E4 and E5, to ensure that the controller card resides at
the secondary address, 170H-177H, rather than the primary
address, 1F0H-1F7H.
2. Move the card from a 16-bit I/O slot to an 8-bit slot to
disconnect the INTRQ output driver.
- On a DTC (Data Technology Corporation) floppy/hard drive
controller card:
1. Install a jumper on pins W3.
2. Move the card from a 16-bit I/O slot to an 8-bit slot to
disconnect the INTRQ output driver.
Once you have disabled drive controller functions on the floppy/
hard drive controller, install the adapter board in a 16-bit slot.
Connecting the Adapter Board and the Drive
------------------------------------------
Use the ribbon cable supplied with the adapter board to connect the
drive to the board. To ensure that the cable is plugged into the
adapter board and the drive correctly, a colored wire is at one edge
of the cable. To connect the drive to the board:
1. Note the number 1 printed on the board next to the connector.
When inserting one end of the cable into the connector on the
adapter board, make sure the colored wire is at the side of the
connector labeled 1.
2. When inserting the other end of the cable into the connector on
the drive, make sure the colored wire is at the inside edge of
the drive connector, next to the J3 power connector.
AT-Bus Interface Characteristics
--------------------------------
The AT-bus interface supports one or two hard drives per adapter
board, and a maximum of two adapter boards - or a maximum of four
drives. When more than one drive is present, a master/slave
relationship exists between the two drives. The host always maintains
control of the bus - no arbitration occurs.
Adapter Kit
-----------
An AT-compatible system with no 40-pin, AT-bus connector on its
motherboard requires a ProDrive AT-Bus Adapter Kit (P/N:
900-00-9002). The adapter kit includes an adapter board and a ribbon
cable, which is used to connect the board to the drive.

QUANTUM PRODRIVE 120/170/210AT PRODUCT MANUAL
General Description
-------------------
The Quantum ProDrive Series is a broad family of high-performance,
3 1/2-inch form factor hard drives manufactured to meet the highest
product-quality standards. These drives use nonremovable rigid disks
as their storage media, have formatted capacities that range from
42 to 210 megabytes, and are available with various interfaces.
Seek Times/Miscellaneous Times:
------------------------------
Times | Typical | Nominal | Maximum |
msec. | Nominal | Condition | Worst-Case |
| Condition | | Condition |
-----------------------+-----------+-----------+------------+
Single Track Seek | 4 | 5 | 5 |
Average Seek | <15 | 15.5 | 16.5 |
Third-Stroke Seek | 15 | 16.5 | 17.5 |
Full-Stroke Seek | 27 | 30 | 33 |
Average Rotational | | | |
Latency | 8.3 | 8.3 | 8.3 |
Sequential Head Switch | 3.0 | 3.0 | 3.0 |
Power-Up Time | 20 | 20 | 20 |
-----------------------+-----------+-----------+------------+
Seek time is the time required for the actuator to seek and settle on
track. Quoted seek times include head settling time, but not command
overhead or rotational latency time.
Seek time is measured by averaging 1000 seeks of the indicated
length. Average seek time is the average time of 1000 random seeks.
When a seek error occurs, recovery for that seek may take up to two
seconds.
Preventive Maintenance
----------------------
The ProDrive 120/170/210AT hard disk drive requires no preventive
maintenance.
Track Format
------------
In the ProDrive Series hard drives, information on the disks defines
the physical sectors. Each sector stores 512 bytes of data and
includes six bytes reserved for ECC. On the ProDrive 120AT and 170AT,
tracks in the outer zone (0-575) contain 48 sectors, while tracks in
the inner zone (576-1122) contain 36 sectors.
On the ProDrive 120AT - which has three disks and five read/write
heads - cylinders in the outer zone have 238 user sectors, while
cylinders in the inner zone have 178 sectors. On the ProDrive 170AT -
which has four disks and seven read/write heads - cylinders in the
outer zone have 334 physical sectors, while cylinders in the inner
zone have 250 sectors. The ProDrive 210AT hard drive has four disks,
seven read/write heads, and eight data zones that have between 39 and
59 sectors per track, as follows:
Zone |User Sectors/Cylinder:
------------+----------------------
Innermost 7| 271
6| 299
5| 327
4| 348
3| 369
2| 390
1| 404
Outermost 0| 411
Sectors are numbered sequentially, beginning with cylinder zero and
head zero, through the innermost cylinder and the head furthest from
the printed-circuit board. The ProDrive 120AT contains 234,454
sequentially-numbered sectors; and the ProDrive 210AT, 408,574
sequentially-numbered sectors.
For every cylinder, two sectors are spares used for defect
management.
Defect Detection
----------------
At sector level, any discrepancy between recorded data and recovered
data constitutes a data error. In high-density digital recording
systems, it is necessary to use an error-detection and correction
scheme to enhance the performance and increase the reliability of the
system.
Data errors are either soft - correctable on retries and not readily
repeatable - or hard - repeatable with high probability. Hard error
may or may not be correctable using ECC (error correction code). The
signal-to-noise ratio of the system affects the occurrence of soft
errors, which represent marginal conditions of the media, heads,
read/write circuitry, or the controller/data synchronizer circuits.
Generally, hard errors occur due to defects, pits, scratches, or thin
spots in the media. The drive can detect and skip defective sectors
on the media. Thus, the drive will not use defective sectors for
storage.
Factory-Found Defects
---------------------
At the factory, disks in the ProDrive 120/170/210AT hard disk drive
are scanned for defective sectors. Factory-found defects are
deallocated prior to shipment. A Defect List, recorded in a reserved
area on the disk, contains the location of all factory-found
defective sectors on the disks.
Automatic Actuator Lock
-----------------------
To ensure data integrity and prevent damage during shipment, all
ProDrive Series hard disk drives feature a dedicated landing zone and
Quantum's patented AIRLOCK. AIRLOCK, locks the headstack in the
landing zone. It consists of an airvane mounted near the perimeter of
the disk stack and a locking arm that restrains the actuator arm
assembly when the disks are not rotating.
When DC power is applied to the motor and the disk stack rotates, the
rotation generates an airflow on the surface of the disk. As the flow
of air across the airvane increases with disk ratation, the locking
arm pivots away from the actuator arm, enabling the headstack to move
out of the landing zone. When DC power is removed from the motor, a
return mechanism automatically pulls the actuator into the landing
zone, where the AIRLOCK holds it in place.
