Maxtor D740X-6L 20.0/40.0/60.0/80.0GB AT 4-9
@ %#
The Maxtor D740X-6L 20.0/40.0/60.0/80.0GB AT hard disk drives can withstand
levels of shock and vibration applied to any of its three mutually perpendicular axes,
or principal base axis, as specified in Table 4-8. A functioning drive can be subjected
to specified operating levels of shock and vibration. When a drive has been subjected
to specified nonoperating levels of shock and vibration, with power to the drive off,
there will be no loss of user data at power on.
When packed in its 1-pack shipping container, the Maxtor D740X-6L drives can
withstand a drop from 30 inches onto a concrete surface on any of its surfaces, six
edges, or three corners. The 20-pack shipping container can withstand a drop from
30 inches onto a concrete surface on any of its surfaces, six edges, or three corners.

Before handling the Maxtor hard disk drive some precautions must to be taken to
ensure that the drive is not damaged. Use both hands while handling the drive and
hold the drive by its edges. Maxtor drives are designed to withstand normal handling,
however, hard drives can be damaged by electrostatic discharge (ESD), dropping the
drive, rough handling, and mishandling. Use of a properly grounded wrist strap to the
earth is strongly recommended. Always keep the drive inside its special antistatic bag
until ready to install.
Note: To avoid causing any damage to the drive do not touch the
Printed Circuit Board (PCB) or any of its components when
handling the drive.
