2.2 S.M.A.R.T.

S.M.A.R.T. is an acronym for Self-Monitoring, Analysis and Reporting Technology, an open standard allowing

disk drives to automatically monitor their own health and report potential problems. It protects the user from

unscheduled downtime by monitoring and storing critical drive performance and calibration parameters. Ideally,

this should allow taking proactive actions to prevent impending drive failure.

Apacer devices use the standard SMART command B0h to read data out from the drive to activate our SMART

feature that complies with the ATA/ATAPI-7 specifications. Based on the SFF-8035i Rev. 2.0 specifications,

Apacer SMART defines vendor-specified SMART Attribute IDs (A0 ~ A5, and 0C). They represent Initial bad

block count, Bad block count, Spare block count, Maximum erase count, Average erase count and Power cycle.

When the Apacer SMART Utility running on the host, it analyzes and reports the disk status to the host before

the device reaches in critical condition.
