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.
