Operations 1-45
•
Disk controller malfunction. Most controllers come with a diagnostic utility
to test controller functioning. If a controller error is found, call the
manufacturer for a replacement.
•
Improper SCSI termination. Many SCSI controllers require that the
terminating resistor packs be removed from all drives between the
controller and last drive. Only the controller itself, and the last drive
connected to the controller (the ends of the “chain”),
should have
terminating
resistor packs left on.
No Hard Disks Found
When you start hard disk setup, if you receive a “No hard drives were found
connected to your computer” message, it means that AlphaBIOS could not
locate a hard drive. The likely conditions that cause this error are:
•
Cable not connected to either the disk or controller. The cable may have
worked loose from the connector on the controller or disk drive. Check the
cable connections, making sure the cable connectors are fully seated.
•
No power to the drive. The power connector may have worked loose from the
receptacle on the drive, or the power cable itself may be malfunctioning.
Check the cable connections, making sure the cable connectors are fully
seated. Try connecting the drive to a different power connector.
•
Disk drive malfunction. The disk drive itself may be malfunctioning and not
responding to requests from the controller. If this is the problem, then it
would appear as though the disk were absent. Replace the drive with a
drive known to be good. If the known good drive is correctly detected, then
your hard drive is defective. Contact the manufacturer for a replacement.
No Partitions on Disk
If hard disk 0 does not have any partitions defined, then a message will appear
when you start hard disk setup, asking if you want to perform an express disk
setup. Express disk setup automatically creates the default disk partition
arrangement on hard disk 0.
For more information on express setup, see Chapter 3.
