4. Mount the drive in the host system and connect cables
Caution. Some mounting kits may contain screws that are too long to be
fully tightened without causing damage to the drive. The maxi-
mum 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.
•MicrosoftTM.SetthedrivetypeinCMOSto“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.
•MacintoshTM.Use a third-party drive utility (most revisions of Apple’s HD
Setup utility only work with drives having special Apple firmware).
Troubleshooting
•Drivedoesnotspinup.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.
