During abnormal operating shock and vibration, there is no physical
damage to the drive, although performance may be degraded during the
shock or vibration episode. When normal operating shock levels resume,
the drive meets its performance specifications.

1.11.2 Power management
This drive provides and uses power-management modes to reduce its
overall power consumption. The level of drive activity for each power-
management mode is described below.
You can customize the power-management modes using the AT inter-
face commands that control the power modes. These commands are
described in the Seagate ATA Interface Reference Manual , publication
number 36111- xxx .
