3.4Drive mounting

You can mount the drive using four screws in the side-mounting holes or four screws in the bottom-mounting holes. See Figure 3 for drive mounting dimensions. Follow these important mounting precautions when mount- ing the drive:

•Allow a minimum clearance of 0.030 inches (0.76 mm) around the entire perimeter of the drive for cooling.

•Use only M3 UNC mounting screws.

•Do not overtighten the mounting screws. Maximum torque: 4.0 inch-lb. (0.4519 N-m).

•Four (4) threads (0.080 inches, 2.032 mm) minimum screw engagement recommended.

•Avoid excessive drive distortion when mounting. Refer to the following specifications for stiffness/deflection information:

Top cover stiffness/deflection

Operating with no performance degradation, emitted noise,	10 mm probe: 1.02kgf or
mechanical damage, or hard errors	5 mm probe: 0.92kgf

Non-operating with no hard errors	20 mm probe: 2kgf at any point of top cover
	20 mm probe: 15kgf at top cover edges only
