Troubleshooting
All PC880B drives are tested at our factory with an Arniga 500 and exten-
sive test software. In spite of this we still receive drives back from users as
being faulty. Of these:
Around 75% have no fault and are returned because the customer has
not read the instructions (usually the part about not changing the isolat-
ing switch while the computer is on).
Around 20% are caused by faulty Amiga 500 computers. power supplies
that are not strong enough, or non-standard setups.
Less than 5% are actually faulty
-
usually due to damage in transit.
