10.0 SMART Feature Set
Note: The following part numbers support the SMART feature set:
 Part Numbers without -S (capacities > 2GB)
 Part Numbers with -S (all capacities)
Self-Monitoring, Analysis, and Reporting Technology (the SMART feature set) is used to protect the user
from unscheduled downtime. By monitoring and storing critical performance and calibration parameters,
SMART feature set devices attempt to predict the likelihood of near-term degradation or fault condition.
Informing the host system of a negative reliability condition allows the host system to warn the user of the
impending risk of a data loss and advise the user of appropriate action.
10.1 SMART Support and Identify Command
When SMART feature set is implemented, the IDENTIFY DRIVE Command returns the following
information for Words 82, 84, and 85:
 Word 82 bit 0 shall be set to ―1‖ to configure the card for SMART feature set support.
 Word 84 bit 1 shall be set to ―1‖ to indicate that SMART self test is supported.
 Word 84 bit 0 shall be cleared to ―0‖ to indicate that SMART error logging is not supported.
 Word 85 bit 0 shall be set to ―1‖ turning on (enabling) the SMART features at plug in until a SMART DISABLE
OPERATIONS command is issued by host.
 Word 87 bit 1 shall be set to ―1‖ turning on (enabling) the SMART self test at plug in.
10.2 SMART Commands
A command code of 0xB0 with a SMART command selected in the Feature Register invokes a SMART
command. Refer to Table 33 for the Feature Register values associated with each SMART command.
