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 model drives 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. Take
care not to stretch or crimp this cable, and do not block the sys-
tem’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.

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 during the format as this is likely to make the
drive inoperable. A low level format, with verification, will typically take two
hours.
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.
Cheetah disc drives are designed to operate with a variety of operating sys-
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.
• Microsoft
TM
. 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
TM
. 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. 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.
