Drive Mounting
The drive will operate in all axes (6 directions). Performance and error rate will stay within specification limits if the
drive is operated in the other orientations from which it was formatted.
The recommended mounting screw torque is 0.45 Nm (4.5 Kgf-cm). The recommended mounting screw depth is 2.5
mm maximum for bottom and 3.0 mm maximum for horizontal mounting.
To avoid performance degradation, mount the drive in the system securely enough to prevent excessive motion or
vibration of the drive at seek operation or spindle rotation, using appropriate screws or equivalent mounting
hardware. Consult with the issuer of this specification for actual application if necessary.
Drive level vibration tests and shock tests are to be conducted with the drive mounted to a table using the bottom
four screws.

Heads Unload and Actuator Lock
Heads are moved out from the disks (unload) to protect the disk data during shipping, moving or storage. At power
down, the heads are automatically unloaded from over the disk area and the head actuator locking mechanism will
secure the heads in the unload position.
