7.7.4 Connector locations Figure 60. Connector locations 7.7.5 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. For reliable operation, the drive must be mounted in the system securely enough to prevent excessive motion or vibration of the drive during seek operation or spindle rotation, using appropriate screws or equivalent mounting hardware. The recommended mounting screw torque is 0.6 - 1.0 Nm (6-10 Kgf.cm). The recommended mounting screw depth is 4 mm maximum for bottom and 4.5 mm maximum for horizontal mounting. If an electrical screw driver is used for moutning screws, a current control model should be used. Drive level vibration test and shock test are to be conducted with the drive mounted to the table using the bottom four screws. 7.7.6 Heads unload and actuator lock Heads are moved out from disks (unload) to protect the disk data during shipping, moving or storage. Upon power down, the heads are automatically unloaded from disk area and head actuator locking mechanism will secure the heads in unload position..

7.7.5 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.
For reliable operation, the drive must be mounted in the system securely enough to prevent excessive
motion or vibration of the drive during seek operation or spindle rotation, using appropriate screws or
equivalent mounting hardware.
The recommended mounting screw torque is 0.6 - 1.0 Nm (6-10 Kgf.cm).
The recommended mounting screw depth is 4 mm maximum for bottom and 4.5 mm maximum for hori-
zontal mounting.
If an electrical screw driver is used for moutning screws, a current control model should be used.
Drive level vibration test and shock test are to be conducted with the drive mounted to the table using the
bottom four screws.
7.7.6 Heads unload and actuator lock
Heads are moved out from disks (unload) to protect the disk data during shipping, moving or storage.
Upon power down, the heads are automatically unloaded from disk area and head actuator locking mech-
anism will secure the heads in unload position
