on your computer’s motherboard (see your computer manual for
connector locations).
Run DiscWizard before installing your drive for customized step-by-step

your drive connector. Pin 1 is marked by a stripe on one side of the
cable.

Handling Precautions
Note. You can mount the drive in any orientation. Usually it is mounted
with the circuit board down.
Disc drives are extremely fragile. Do not drop or jar the drive.
3. Secure the drive in the computer using four 6-32 UNC mounting
screws in either the side-mounting or bottom-mounting holes. Insert
the screws no more than 0.22 inch (5.58 mm) into the bottom-mounting
holes and no more than 0.20 inch (5.0 mm) into the side-mounting
holes.
Keep the drive in its antistatic bag until you are ready to install it.
Protect your drive from static discharge by wearing a grounded
wrist strap throughout the installation process.
Caution. Do not overtighten the screws or use metric screws. This
may damage the drive.
!
Always handle the drive by the edges or frame.
Configuring the BIOS
Do not apply pressure or attach labels to the circuit board or the
top of the drive.
For your computer to recognize your new drive, configure your
