To determine what SCSI IDs have already been assigned to which devices, go

to the

Hard Disk Toolkit™ PE

folder in the

Utilities

folder on your hard

disk and run

HDT Primer™ PE

. HDT Primer will scan your SCSI buses and

display the Bus number (0 or 1), the SCSI ID, name, and other parameters of all

of the SCSI devices on the bus (see example below).

The 20 MB per second UltraSCSI bus is Bus 1; the conventional 5 MB per

second SCSI bus is Bus 0.

Ensuring proper termination

For a SCSI chain to work properly, it must be terminated correctly. The basic

rule about SCSI termination is simple: the device at the end of the chain must

terminated

. Active termination is recommended for external SCSI chains, as

it reduces noise and increases reliability. Devices located between the

computer and the end of the chain must be unterminated.
