enables a drives internal status to be monitored through diagnostic commands at
the host level and during offline activities. S.M.A.R.T. devices employ data analysis
algorithms that are used to predict the likelihood of some near-term degradation
or fault conditions. When used with a S.M.A.R.T. application, the drive can alert
the host system of a negative reliability status condition. The host system can
then warn the user of the impending risk of data loss and recommend an appro-
priate action.

•
Security Mode feature set allows the user to create a device lock password that
prevents unauthorized hard disk access even if the drive is removed from the host
computer. The correct password must be supplied to the hard drive in order to
access user data. Both the User and Master Password features are supported,
along with the High and Maximum security modes. The Master Password Revision
code is also supported. This feature varies by drive configuration and may not be
available on all configurations.
