Troubleshooting

Before calling Seagate Technical Support, please read and
consider the possibilities discussed below. The suggestions
presented here will resolve the majority of installation problems.

General installation troubleshooting

• Check system compatibility. This is a SCSI interface de-

vice. Check your system documentation to ensure that is
supports SCSI interface devices.

• Check the drive ID assigned. Model "N" has three drive ID

jumper positions on the drive. See Figure 3a. Models "W" and
"WC" have four drive ID jumper positions. See Figures 3b and
3c.

• Check the drive operating feature jumpers. See Figure 3b

and associated explanations.
