PREMIO Troubleshooting Guide
SCSI Hard Disk Drive (HDD)

Jump to the self-diagnostic flowchart, or select the specific problem you're having with your SCSI HDD:

My SCSI controller doesn't detect the SCSI drive.
My SCSI drive is not spinning up.
I'm getting a SCSI ID conflict with my SCSI drive.

MY SCSI CONTROLLER DOESN'T DETECT THE SCSI DRIVE
1.
Check the SCSI cable and power connector. Make sure the SCSI cable is attached to the SCSI controller and SCSI HDD properly. Refer to your SCSI controller user's manual for more information.
2. Lastly, check the SCSI HDD ID and termination.

MY SCSI DRIVE IS NOT SPINNING UP
1. Try a different power connector to the SCSI HDD.
2. On some SCSI HDD, there's a spin-up jumper that tells the SCSI HDD to spin up only when the SCSI controller sends a command to the SCSI HDD.
3. Consult your SCSI HDD user's manual and configure the SCSI HDD so that it will spin up automatically when power is applied to your system.

I'M GETTING A SCSI ID CONFLICT WITH MY SCSI DRIVE
1. Each SCSI HDD on the SCSI cable must have a unique SCSI ID number assigned to it.
2. If you have a CD-ROM, scanner, or tape backup drive attached to your SCSI controller, make sure the SCSI ID is also different from the SCSI HDD.

CONFIGURE SCSI HDD ID AND TERMINATION
1. A SCSI HDD must be configured with a unique SCSI ID number. If you only have one SCSI HDD attached to your SCSI controller, then it is recommended you configure it to SCSI ID 0. If you have two or more SCSI HDDs attached to the same SCSI cable, you must configure each HDD with a unique SCSI ID number.
2. In addition, if you only have one SCSI HDD present, then you must make sure it is also terminated. For two or more SCSI HDDs on the same SCSI cable, ensure that the last SCSI HDD on the cable is terminated; every other SCSI HDD between the SCSI controller and the last SCSI HDD should not be terminated.

BOOT INTO OPERATING SYSTEM AND PARTITION SCSI HDD
1. If you're using Windows 95/98, hit the F8 key at startup to get to the boot menu. Then select "Command Prompt Only."
2. At the C:> prompt, type in fdisk and see if you can create a partition for the SCSI HDD.
3. If fdisk cannot create the partition, check and make sure you've loaded the SCSI drivers correctly.

CHECK SCSI CABLE AND POWER CONNECTOR
1. Before opening the system, make sure it is powered off with the power cord unplugged.
2. Eliminate static discharge by first touching the back of the power supply unit.
3. Once the case cover is removed, locate the SCSI HDD and your SCSI controller card (either as an addon card or integrated on to the motherboard)
4. Check to make sure the SCSI cable from the SCSI HDD and SCSI controller is connected properly and secure. Also, check to see if the power connector is connected correctly to the SCSI HDD.
5.If you have a spare SCSI cable, then swap it out with the existing cable, and see if the problem's caused by a defective SCSI cable.
