ezHDDSmart - HDD Health Checkup
What is S.M.A.R.T.?
S.M.A.R.T. (Self-Monitoring Analysis and Reporting Technology) is an interface between the BIOS and
a computer’s hard disk. It is a feature of the Enhanced Integrated Drive Electronics (EIDE) technology
that controls access to the hard drive. If S.M.A.R.T is enabled when a computer is set up, the BIOS can
receive analytical information from the hard drive and determine whether to send the user a warning
message about possible future failure of the hard drive.
SMART monitors a set of drive attributes, such as temperature, throughput performance and the number
of hours the drive has been powered on. It compares these attributes to a corresponding set of thresholds.
If an attribute drops below its threshold, the drive is no longer considered fit for use and should be
replaced immediately. Not all attributes are available on all drives, however. It is the responsibility of the
drive manufacturer to include SMART support. Sometimes the NVR’s HDD will crash or cannot
read/write the data unexpectedly. To avoid this problem happen again and again, our ezHDDSmart will
provide the directly or indirectly affect hard disk health status and give statistical information. It can
provide the hard disk reliability and the failure prediction function and send the user a warning message
about possible future failure of the hard drive. Please click “ezHDDSmart” from “ezTools”
