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.
