❑
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 connec-
tor, 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.
❑
For some IDE devices, because of their
specifications, the drive may not appear in
the BIOS display during system startup. As
long as the drive is identified after the OS
has started, this is not a problem.
