Reserved Positions

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.

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.

Terminator Power

Term. Power to SCSI Bus

Host adapter or other device provides term. power to external terminator.

inoperable. A low level format, with verify turned on, will typically take two hours for ST373405 models and 90 minutes for ST336605 models.

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.

•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. 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

4. Connect the drive activity LED (optional)

Connect the Drive Activity LED cable to J6 pins 11 and 12 (see Figure 2), or connect a drive ID and Drive Activity LED cable to J5, depending on host system requirements.

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 and LCV 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 and LWV 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 orienta- tion.

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.

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

the next item below. 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.
