Note. LC drives cannot be configured to provide termination power to the bus.

4. 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 mounting 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.

5. Format the drive

The drive has been low level formatted at the factory. You do not need to

perform another low level format on this drive unless you decide to perform

certain 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

inoperable. A low level format, with verify turned on, will typically take up to

one hour.

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

hard disc drive if there is one.

c. Format the drive.

Caution. Formatting a drive erases all user data. Be sure that you under-

stand this principle before formatting any hard disc drive. It is not

necessary to format a drive that previously has been used to

store data, unless your intention is to erase all user data. Seagate

is not responsible for lost user data.

Barracuda disc drives are designed to operate with a variety of operating

systems. Please refer to your system or SCSI controller manual for informa-

tion about formatting and setting up the drive. Some quick desktop system

notes are provided below.

• Microsoft

. Set the drive type in CMOS to “Zero,” “None,” or “No hard

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.

• Macintosh

. Use a third-party drive utility (most revisions of Apple’s HD

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.

Warranty. Contact your place of purchase or our web site (above).

Return Merchandise Authorization (RMA). Before returning the drive, verify that it

is defective. Seagate Worldwide customer service centers are the only facilities autho-

rized to service Seagate drives. Contact nearest center for return procedures and trade

regulations.

Shipping the drive

Caution. 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 electrical and physical damage in transit.
