Note. Drives in the ST9235 family are usually installed in note-
book or laptop systems. Special training or tools may be
needed to service these computers. In some instances,
opening the case may void your warranty. Be sure to
review the terms and conditions of your system warranty
before opening the system enclosure.
Warning. Always power off and unplug your computer system
before touching any internal components.
Observe static discharge precautions.
•Keep the drive in its static-shielded bag until you are ready to
complete the installation.
•Do not touch the PC board or the I/O connector pins.
•Always handle the drive by its edges or frame. Never apply
pressure to the PC Board or to the drive’s top cover.
•Use a grounded wrist strap. If none is available, ground
yourself by touching the metal chassis of the system before
handling any components.
•Use antistatic padding on all work surfaces and avoid static-
inducing carpeted areas.
Inspection. When you are familiar with the handling precautions
listed above, inspect the drive. If it appears to be damaged,
contact your distributor or dealer immediately.
Handle drives carefully. Improper handling during transit or
shipping accounts for many installation problems. Even minor
bumps can exert relatively large G forces on these drives. Always
handle the drive carefully. In addition, do not attach any labels to
the drive top cover, as they may prevent proper ventilation.
