No newer firmware is available for it than what it has. ID# ATTRIBUTE_NAME FLAGS VALUE WORST THRESH FAIL RAW_VALUE 9 Power_On_Hours -O--CK 096 096 000 - 16513 However... SMART Extended Self-test Log Version: 1 (1 sectors) Num Test_Description Status Remaining LifeTime(hours) LBA_of_first_error # 1 Extended offline Completed without error 00% 3 - # 2 Short offline Completed without error 00% 2 - # 3 Extended offline Completed without error 00% 8 - # 4 Extended offline Completed without error 00% 2 - # 5 Offline Completed without error 50% 2 - # 6 Extended offline Completed without error 00% 2 - # 7 Short offline Completed without error 00% 8 - # 8 Extended offline Completed without error 00% 6 - # 9 Extended offline Completed without error 00% 5 - #10 Short offline Completed without error 00% 6 - #11 Extended offline Completed without error 00% 5 - #12 Short offline Completed without error 00% 19 - #13 Extended offline Completed without error 00% 11 - #14 Short offline Completed without error 00% 0 - Clearly those lifetime numbers are bogus, as well as sometimes reporting a lower lifetime value than the test before it. It's getting younger!! My SSD found the fountain of youth! The #1 entry was just done a week ago. Is it possible the test itself is bogus? I've done ~150 "pull the cord" poweroffs while doing writes. No Btrfs complaints on the next boot, and no errors when scrubbing. So it's probably decently well behaved. But firmware defects can be pernicious so if it suddenly goes kaboom I won't be shocked. -- Chris Murphy _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx
