6.2 S.M.A.R.T.

S.M.A.R.T. is an abbreviation for Self-Monitoring, Analysis and Reporting Technology, a self-monitoring

system that provides indicators of drive health as well as potential disk problems. It serves as a warning

for users from unscheduled downtime by monitoring and displaying critical drive information. Ideally, this

should allow taking proactive actions to prevent drive failure and make use of S.M.A.R.T. information for

future product development reference.

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

S.M.A.R.T. feature that complies with the ATA/ATAPI specifications. S.M.A.R.T. Attribute IDs shall

include initial bad block count, total later bad block count, maximum erase count, average erase count,

power on hours and power cycle. When the S.M.A.R.T. Utility running on the host, it analyzes and reports

the disk status to the host before the device reaches in critical condition.

Note: attribute IDs may vary from product models due to various solution design and supporting

capabilities.
