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 SAFD 18P uses the standard SMART command B0h to read data from the drive for SMART feature

as the SATA Rev.2.6 ATA/ATAPI-7 specifications. Based on the SFF-8035i Rev. 2.0 specifications, Apacer

SMART defines 3 vendor-specified SMART Attribute IDs (E5h, EAh-EBh, and E8h) in SAFD 18P. They

represent Flash ID, maximum erase count, average erase count, good block count, free-list block count, and

firmware version information. When the Apacer SMART Utility running on the host, it analyzes and reports the

disk status to the host before SAFD 18P is in critical condition.
