SCSI Hardware Issues
SCSI bus cables and terminators may affect drive performance. IBM cables and
terminators are designed specifically to keep the SCSI bus as free of noise as
possible. Use of non-IBM cables or terminators may adversely affect the SCSI bus
performance. If IBM service personnel analysis indicates a problem with non-IBM
cables, it may be necessary for the customer to replace them with the appropriate
IBM cables.
Microcode Updates
IBM constantly works to provide the best possible products. To make certain that
the drives work their very best, IBM occasionally releases changed microcode for
the drives. When a microcode change is developed, IBM makes it available to you
through the service organization or by electronic delivery.

Summary
Your drive must be installed in the cleanest possible environment. Additionally,
IBM drives require high quality, data grade media and cleaning on a regular basis.
Media must also be stored and handled properly. Improper use, storage or
handling of drives or media may void your IBM warranty or service agreement
If a drive stops functioning due to a component failure during the drive warranty
or maintenance time, IBM will replace the drive unit. IBM will replace any
defective drive under the terms and conditions of the IBM warranty or service
agreement. It is our objective to work with you to identify the cause of any drive
problems and provide a solution.
