WD Purple™ PR1200M
Self-Monitoring, Analysis, and Reporting Technology (S.M.A.R.T.) — S.M.A.R.T.
enables a drive's 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 appropriate action.
ATA Security — The drive supports the ATA Security Mode Feature set. The ATA
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.
