7.6.1 Drive orientation
The balanced rotary arm actuator design of the drive allows it to be mounted
in any orientation. All drive performance evaluations, however, have been
done with the drive in horizontal (discs level) and vertical (drive on its side)
orientations, which are the two preferred mounting orientations. To ensure
proper performance, rigidly mount the drive to the host system in accordance
with the requirements in this product manual.

7.6.2 Cooling
Ensure that the enclosure you use provides adequate cooling so that the
ambient temperature immediately surrounding the drive does not exceed
temperature conditions specified in Section 7.4.1. Ensure that you provide
adequate air circulation around the printed circuit boards (PCBs) to meet
the requirements of Section 7.4.1.
