SMART Subcommand Set
The SMART RETURN STATUS (DAh) command returns a pass/fail value based on the
current status of the Z-P230 PATA SSD. The BIOS or system software that interfaces to
SMART should issue this command at boot up and upon resume from a standby or
hibernate condition. If the status returned is PASS, the boot up or resume sequence
should continue as normal. If however the status returned is FAIL, the BIOS or system
software should issue a warning to the end user that their SSD is approaching it's drive
wear-out condition and recommend that the end user back up their SSD.
