Do not touch the exposed printed circuit board or any electronic components. [. . . ] Performance and error rate will stay within specification limits if the drive is operated in the other permissible orientations from which it was formatted. Thus a drive formatted in a horizontal orientation will be able to run vertically and vice versa. The recommended mounting screw depth is 3. 0±0. 3 mm for bottom and 3. 5±0. 5 mm for horizontal mounting. The user is responsible for using the appropriate screws or equivalent mounting hardware to mount the drive securely enough to prevent excessive motion or vibration of the drive at seek operation or spindle rotation.
