G-Force Protection
When a laptop is dropped, the most
catastrophic damage to the hard drive
occurs when the head scrapes across
the surface of the disk, causing potential
data loss. The G-Force Protection
feature, an optional drop sensor, protects
the Momentus 5400.6 drive against
shock by sensing when the system is in
a free-fall state, moving the heads off
the platter and locking them in place—all
within three-tenths of a second.
