4-10 Maxtor D540X-4K 20.4/40.0/60.0/80.0 GB AT
The Maxtor D540X-4K 20.4/40.0/60.0/80.0 GB 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 D540X-4K 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.
