S.M.A.R.T.

S.M.A.R.T. (ang. Self-Monitoring, Analysis and Reporting Technology) is a system for monitoring and notification of hard disk operation errors to increase the security of stored data. The use of this system allows to anticipate and prevent impending failures (e.g. by monitoring the temperature overheating risks).

S.M.A.R.T. monitors many parameters of the hard disk by constant access to a device status. Monitoring includes:

•number of start / stop cycles (Start / Stop Count),

•disk temperature (Celcius),

•frequency of errors during reading process (Read Error Rate),

•the number of reallocated sectors (Reallocated Sector Count),

•the number of attempts to start the disk axis (Spin Retry Count).

Error analysis, based on the prediction of disk damage based on constantly monitored parameters (attributes), allows for earlier notice about potential problems.
