6. Mount the drive in the host system and connect cables
Note. LC drives are designed to be attached to a carrier or tray and inserted
into the host system without I/O or power cables.
Caution. Some mounting kits may contain screws that are too long to be fully
tightened without causing damage to the drive. The maximum
length for screws to extend into the drive mounting holes is 0.15 inch
(3.82 mm), measured from the outer surface of the drive.
a. Mount the drive to the host system's chassis using four 6-32 UNC screws.
Two mounting holes are in each side of the drive and there are four mount-
ing holes in the bottom of the drive. Do not over-tighten or force the
screws. You can mount the drive in any orientation.
b. Connect the SCSI I/O cable into the drive's SCSI connector. Do not stretch
or crimp this cable, and do not block the system's air flow.
Note. For Ultra2 and faster operation, a twisted pair LVD cable is required.
c. Connect the DC power cable to the drive. See Figure 4.

Single-ended I/O
A jumper here forces single-ended
I/O operation.
No jumper allows host to select either
single-ended or LVD operation.
Delay Motor Start option (valid
only if the Enable Motor Start
jumper is not connected)
Disable the Delay Motor Start option.
Motor start delay equal to the
SCSI ID multiplied by 12 seconds.
Motor Start option
Disable motor start (default). The
drive starts according to the Delay
Motor Start option.
Enable motor start. The drive waits for
the Start Unit command from the host
before starting the spindle motor.
Write Protect option
Write protect = Off (enables writing).
Write protect = On (disables writing).
Parity Check option
Enable parity check of SCSI bus.
Disable parity check.
Terminator Power
Term. Power to SCSI Bus
Host adapter or other device provides

7. Format the drive
Pin 1
The drive has been low level formatted at the factory. You do not need to per-
form another low level format on this drive unless you decide to perform cer-
tain diagnostics through the host adapter. If you do decide to perform a low
level format, do not abort the format as this is likely to make the drive inopera-
ble. A low level format, with verify turned on, will typically take up to one hour.
(default)
Protect against power failure or other power interruptions during the format.
a. Turn on DC power to the host system.
b. Boot the system from a system floppy, CD, or from a previously installed
(default)
hard disc drive if there is one.
c. Format the drive.
Caution. Formatting a drive erases all user data. Be sure that you understand
(default)
Barracuda disc drives are designed to operate with a variety of operating sys-
(default)
tems. Please refer to your system or SCSI controller manual for information
about formatting and setting up the drive. Some quick desktop system notes
are provided below.
(default)
• Microsoft
drive installed." Use FDISK.EXE and FORMAT.EXE. Systems using Win-
dows 98 or later can create one single partition (drive letter) on the drive.
(default)
• Macintosh
Setup utility only work with drives having special Apple firmware).
Troubleshooting
• Drive does not spin up. Check cables and all jumper settings. Make sure
cable pin 1 (edge stripe) matches PCB pin 1.
• Drive spins, but no LED on/off activity. Check SCSI ID setting. Set the ID
so that each device on the SCSI chain has its own unique ID. See also the
next item below. Host I/O controller is usually ID 7.
• Computer does not seem to recognize the drive. Verify that the drive is
enabled by the SCSI host adapter setup utility.
• FDISK does not detect the drive. Run the FDISK program located on your
Windows startup diskette. Type fdisk/status to verify that your hard drive is
present.

Shipping the drive
Back up the data before shipping. Seagate assumes no responsibility for data lost during
shipping or service. Shipping drive in an unapproved container voids the warranty. Pack
the drive with original box and packing materials. Use no other materials. This prevents
