Master/slave configuration
--------------------------
You must establish a master/slave relationship between multiple
drives attached to a single AT bus. You can configure a drive to
become a master or slave by setting the master/slave jumpers.
If only one jumper is installed or if neither jumper is installed,
then the jumper settings on each drive determine whether that drive
is a master or a slave.
Alternatively, you can configure an ST9300 family drive as a master
or slave using the cable select option. This requires a specialized
daisy-chain cable that grounds pin 28 (CSEL) on one of its two drive
connectors. If you attach the drive to the grounded CSEL connector,
it becomes a master. If you attach the drive to the ungrounded CSEL
connector, it becomes a slave. To use this option, the host system
and both drives must support cable select. To configure an ST9300
family drive for cable select, install both master/slave jumpers.
Regardless of which jumper settings are used, the slave drive must
assert the DASP- signal at power up and the master drive must monitor
DASP- at power up for the slave to be recognized.

Remote LED
----------
The drive indicates activity to the host through the DASP- line (pin
39) on the ATA interface. This line may be connected to a drive
status indicator driving an LED at 5V. The line has a 30 mA nominal
current limit.

Notes On Installation
=====================
Mounting the drive
------------------
You can mount ST9300 family drives in any orientation. Allow a mini-
mum clearance of 0.030 inches (0.76 mm) around the entire perimeter
of the drive for cooling.These drives conform to the industry-
standard MCC direct-mounting specifications and require the use of
MCC-compatible connectors in direct-mounting applications.
NOTE
The I/O connector pins may extend up to 0.010 inches beyond the edge
of the head/disc assembly.
CAUTION
To avoid damaging the drive:
- Use M3X0.5 metric mounting screws only.
- Do not insert mounting screws more than 0.150 inches (3.81
mm) into the mounting holes.
- Do not overtighten the screws (maximum torque: 3 inch-lb).
Handling and static-discharge precautions
-----------------------------------------
After unpacking, and before installation, the drive may be exposed to
potential handling and ESD hazards. It is mandatory that you observe
standard static-discharge precautions. A grounded wrist-strap is pre-
ferred.
Handle the drive only by the sides of the head/disc assembly. Avoid
contact with the printed circuit board, all electronic components
and the interface connector. Do not apply pressure to the top cover.
Always rest the drive on a padded antistatic surface until you mount
it in the host system.
Attaching Cables
----------------
This drive is designed for a host computer that supplies interface
signals and +5V power through a single 44-pin connector and cable.
ATA interface
-------------
The ST9300 family drives use the industry-standard ATA task file
interface. The drives support both 8-bit and 16-bit data transfers.
They support ATA programmed input/output (PIO) modes 0, 1 and 3, as
well as ATA single-word DMA modes 0, 1 and 2, and ATA multiword DMA
modes 0 and 1. The ST9300 family drives also support the use of the
IORDY signal to provide reliable high-speed data transfers.
The drives can differentiate between a hard reset and a soft reset
while in Sleep mode. You can use a daisy-chain cable to connect two
drives using the same AT host bus.
Interface connector
-------------------
The drive connector is a 44-conductor connector with 2 rows of 22
male pins on 0.079-inch (2 mm) centers (see Figure 4). The mating
cable connector is a 44-conductor, nonshielded connector with 2 rows
of 22 female contacts on 0.079-inch (2 mm) centers. The connectors
should provide strain relief and should be keyed with a plug in
place of pin 20.
The ST9300 family drives are designed to support the industry-
standard MCC direct-mounting specifications. When installing these
drives in fixed mounting applications, use only MCC-compatible
connectors such as Molex P/N 87368-442x. For applications involving
flexible cables or printed circuit cables (PCCs), use Molex part
number 87259-4413 or equivalent to connect the drive to the system.
Select a connector that provides adequate clearance for the master/
slave configuration jumpers if the application requires the use of
such jumpers. The ATA interface cable should be no more than 18
inches long.

ECC testing
-----------
When an ST9300 family drive performs hardware-based ECC error
correction on-the-fly, the drive does not report an ECC error. This
allows ECC correction without degrading drive performance. Some older
drive diagnostic programs test ECC features by creating small data
errors and then checking to see if they are reported. Such tests,
when run on an ST9300 family drive, may incorrectly report an ECC
detection failure because the drive hardware corrects the data
automatically, avoiding the error rather than reporting it. Such a
report does not indicate a drive malfunction.
Power-management modes
----------------------
Power management is required for low-power and portable computer
systems. In most systems, you can control power management through
the system setup program. The ST9300 family drives feature several
power-management modes, which are described briefly below:
Active mode
-----------
The drive is in Active mode during the read/write and seek
operations.
Idle mode
---------
At power-on, the drive sets the idle timer to enter Idle mode after
5 seconds of inactivity. You can set the idle timer delay using the
system setup utility. In Idle mode, the spindle remains up to speed.
The heads are parked away from the data zones for maximum data
safety. The buffer remains enabled, and the drive accepts all
commands and returns to Active mode any time disc access is
necessary.
Standby mode
------------
The drive enters Standby mode when the host sends a Standby Immediate
command. If the standby timer has been set by the host system, the
drive can also enter Standby mode automatically after the drive has
been inactive for a specifiable length of time. The standby timer
delay is system-dependent and is usually established using the system
setup utility. In Standby mode, the buffer remains enabled, the heads
are parked and the spindle is at rest. The drive accepts all commands
and returns to Active mode any time disc access is necessary.
Sleep mode
----------
The drive enters Sleep mode after receiving a Sleep Immediate command
from the host. The heads are parked and the spindle is at rest. The
drive leaves Sleep mode when a Hard Reset or Soft Reset command is
received from the host. After receiving a soft reset, the drive exits
Sleep mode and enters Standby mode with all current emulation and
translation parameters intact.
Rest mode
---------
Some host systems reduce drive power consumption by removing all
power from the drive, using a state known as Rest mode. As the drive
enters Rest mode, the host saves drive state information (including
current logical geometry, set feature parameters, cache status and
task file registers) before powering down the drive. After power is
restored, the host restores the drive to its prerest condition. Rest
mode is implemented using three commands: Rest, Read Drive State and
Restore Drive State. The Rest command prepares the drive for a
subsequent Read Drive State command. The Read Drive State com-mand
captures the state of the I/O registers. The Restore Drive State
command reads the drive state data from memory and restores the drive
state based on this data.
Idle and standby timers
-----------------------
The drive sets the default time delay for the idle timer at power-on.
In most systems, you can set this delay using the system setup
utility. Each time the drive performs an Active function (read, write
or seek), the idle and standby timers are reinitialized and begin
counting down from their specified delay times to zero. If the idle
timer reaches zero before any drive activity is required, the drive
makes a transition to Idle mode. If the host has set the standby
timer, the standby countdown continues. If the host has not set the
standby timer, the drive remains in Idle mode. If the standby timer
reaches zero before any drive activity is required, the drive makes a
transition to Standby mode. In both Idle and Standby mode, the drive
accepts all commands and returns to Active mode when disc access is
necessary.
Deferred spinup
---------------
ST9300 family drives may be factory-configured for deferred spinup.
If configured for deferred spinup, the drive does not spin up
immediately after power-on but waits until a command is received from
the host. At power-on, the drive posts a status of 80H and all
master/slave protocols are completed before the drive reports a
status of 50H. After the drive receives a command from the host, it
executes the normal spinup/upload process. If the host issues a soft
reset before the drive spins up, the drive responds normally, except
that it does not spin up until receiving a command from the host.
Formatting and partitioning the drive
-------------------------------------
CAUTION
Formatting or partitioning a drive that contains data destroys that
data. Make sure all data has been safely backed up before
repartitioning or reformatting a drive. Seagate Technology assumes no
liability for lost data.
Low-level formatting
--------------------
Seagate AT Interface drives are low-level formatted at the factory
and do not require additional low-level formatting before use.
Partitioning
------------
The partitioning process subdivides a single disc drive into
partitions that behave as separate logical drives (labeled C, D, E,
etc.). You can also set up the entire disc as a single partition.
NOTE
If you are using a version of DOS prior to Version 4.0, the operating
system cannot access more than 32 Mbytes in a single partition.
Therefore, you must divide a drive with a capacity of over 32 Mbytes
into several smaller parti-tions. We do not recommend using ST9300
family drives with DOS versions prior to Version 3.3.
