1.3 General caution
!Do not apply force to the top cover (See the figure title "Handling Precaution 1" on page 4).
!Do not cover the breathing hole on the top cover (See the figure title "Handling Precaution 2" on
page 4).
!Do not touch the interface connector pins or the surface of the printed circuit board.
!The drive can be damaged by shock or ESD (Electric Static Discharge). Any damages incurred to the
drive after removing it from the shipping package and the ESD protective bag are the responsibility of
the user.
