Figure 2. Option select jumpers.
4. Connect the Drive Activity LED (optional)
Connect the Drive Activity LED cable to J6 pins 11 and 12, or connect a
drive ID and Drive Activity LED cable to J5, depending on the host system.
5. Check the other available jumper settings
Select other options on J2 as illustrated in Figure 2. Do not change these
unless instructed to do so by the host system documentation.
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.
a. Mount LW drives to the 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. Take
care not to stretch or crimp this cable, and do not block the system’s
cooling air flow with the cable.
Note. For Ultra2 and faster operation, special twisted pair LVD
cables are
required
.
c. Connect the DC power cable to the drive. See Figure 3.
Figure 3. Cable connections and external termination
7. 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, may take two hours.
Protect against power failure or other power interruptions during the format.
a. Turn on DC power to the host system and boot the system from a
system floppy, CD, or from a previously installed hard disc drive if
there is one.
b. Format the drive.
Caution. Formatting a drive erases all user data. It is not necessary to for-
mat a drive that previously has been used to store data, unless
your intention is to erase all user data. Seagate®is not responsi-
ble for lost user data.
Cheetah X15 36LP disc drives are designed to operate with a variety of
operating systems. Please refer to your system or SCSI controller manual
for information about formatting and setting up the drive. Some quick desk-
top system notes are provided below.
•MicrosoftTM.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.
•MacintoshTM.Mac OS 8.6, 9.x and OS X: Use Apple’s Drive Setup utility
to partition and initialize the drive. Mac OS 8.5 or earlier: Use a third-
party drive utility. For more information, refer to: www.apple.com.
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. The host I/O controller is usually ID7.
•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.
