Mounting orientation

Although, the drive is most often mounted horizontally, this drive will operate in all axes (6 directions):

Mount the HDD with M3 screws using 4 screws holes, taking care to avoid using excessive ("distorting") force which could bend the chassis slightly. When the HDD is mounted, use screws with the following specifications: i) M3 (screw engagement of 3.0mm max. However, do not use both bottom and side screw hole at the same position simultaneously.) ii) The torque for fixing the screws is 3±0.5kgcm (2.6±0.4 lb. inch).

During operation, consider an appropriate cooling to keep the temperature of center of HDD top cover less than 62°C.

Note on mounting for systems designers: Take care that the system chassis are flat enough. Any distortion of HDD over 0.020mm should be avoided. Also -- to optimize performance -- the inertia of the chassis around the Z-axis of the gravity center of the device must be more than 7 X 10-4 kg m2. In case of general Sub-Notebook PC (Weight: 1.7kg), the inertia of the chassis around the Z-axis of the gravity center of the device is greater than 100 X 10-4 kg m2. Therefore, the required inertia level has no problem with the general electronic equipment. See the DK23FB spec for more details.
