General troubleshooting procedures

The following is a list of general troubleshooting procedures. Solu-
tions for specific problems are provided on subsequent pages.
Warning. Always turn off the computer before changing jumpers,
moving cables or touching any internal components.
Verify hardware compatibility. Check the documentation
for your drive, host adapter and computer to confirm that these
components are compatible.
Verify your hardware configuration. Check the documen-
tation for your drive, host adapter and computer to confirm
that all jumpers are set appropriately.
Check all cables. Make sure that all cables are securely
connected. Printed circuit and ribbon cables are quite fragile.
Check to see that they are not crimped or damaged. Make
sure that pin 1 of the interface cable is connected to pin 1 of
the interface connector on the drive and on the computer.
Most ribbon cables have a stripe down one side to designate
pin 1. The location of pin 1 on the drive interface connector is
shown in Figure 1 on page 4.
Check all cards. If your computer has expansion cards,
check to see that they are inserted completely into their slots
on the motherboard and are secured with appropriate
mounting screws. Make sure that full-size (16-bit) cards are
not plugged into half-size (8-bit) slots.
