Make sure that terminators are connected and/or
set correctly.
→
Terminators must be connected at both ends
of the SCSI bus.
• If the remote end of the SCSI bus is a cable
(connector), make sure that a terminating
connector is connected to it.
• If the remote end of the SCSI bus is an
internal drive, make sure that the drive
terminator setting is ON.
• If the remote end of the SCSI bus is an
external drive, make sure that a terminating
connector is connected to it.
• If the remote end of the SCSI bus is a SCSI
board or motherboard, make sure that the
SCSI BIOS is set up correctly. (Refer to
the appropriate documentation for details.)
• Make sure that the terminator setting is
OFF for any drive that is not at the remote
end of the SCSI bus.
❑
If the SCSI connector is a pin-type connector,
make sure that none of the pins are bent
(internal drive 50-pin connector, internal or
external cable 68-pin connector, external cable
50-pin [PIN type] connector, etc.).
→
If pins are bent, do not try to bend them back
into position. Replace the drive or cable.
❑
Make sure that the SCSI BIOS is correctly set
up. (Refer to the setup procedures in the
appropriate documentation, if available. Some
SCSI BIOS are designed not to allow changes.)
❑
Make sure that the drive is connected in the
proper position according to the system
configuration.
❑
Make sure that the device driver is installed
correctly.
→
In some cases, the device driver may be
installed automatically. In other cases, it may
be necessary to install the device driver
manually. In still other cases, the device
driver may be incorporated into the product.
Refer to the User’s Guide for details.
❑
Make sure that the device driver started
correctly.
