Drive Mounting

Drive Orientation
The drive may be mounted in any orientation. For best results, the
drive should be formatted in its final mounting orientation.

Important Note: Using mounting screws larger than specified maximum
dimensions could damage the drive.

Bottom Mounting
6-32 UNC screw, 4 places. Maximum length into drive frame: 0.20-inch.

Side Mounting
6-32 UNC screw, 4 places. Maximum length into drive frame: 0.13 inch.

Seagate's ST3144 Family drives can be installed in laptop systems.
These computers require qualified or factory trained technicans to
perform peripheral upgrades. Be sure to review the terms and
conditions for your system warrenty before opening the system
enclosure. All ST3144 Family drives automatically park their heads
at power-down.

Power Connection
Connect a system power cable to the drive power connector. The ST3144
Family drives support both 3-pin and 4-pin DC power connector

Attach AT Interface Cable
Use a 40-pin AT interface connector cable. Pin 20 has been removed on
the connector for keying purposes. A dual-drive system will require
an 40-pin AT interface daisy-chain cable.

Note: Most cables have a colored stripe down one side to designate
the Pin 1 location. Make sure Pin 1 on the interface cable connector
is connected to Pin 1 on the drive interface connector and Pin 1 on
the host connector.

   |1  2  3  4|  2 = +12 Volts Return

Low-level formatting
Seagate AT Interface drives are low-level formatted at the factory
and do not need low-level formatting. If an installed drive is low-
level formatted, all user data will lost. Seagate Technology assumes
no liability for lost user data.

Maintenance and repair
Seagate disc drives do not require any preventive maintenance. The
head/disc assembly is sealed and does not contain any user-
serviceable components. Tampering with the factory seal voids the

Error Correction
The ST3144 Family drives use 4 bytes of Error Correction Code (ECC)
with Read/Write Long commands. Based on the drive type, some systems
BIOS will lock for 7 Bytes of ECC. If your system expects 7 bytes of
ECC, some drive diagnostics programs will return false drive failures
Contact your system dealer for information on configuring your
system to receive 4 bytes of ECC.

Power Management
The ST3144 Family feature four-phase power management with Active,
Idle, Standby and Sleep modes. Power management is required for low-
power portable systems, an dis enabled through a system-dependent
set-up procedure.
