1trkmind Posted April 27, 2020 Share Posted April 27, 2020 (edited) Hey all. I upgraded my 3tb parity disk with a 10tb disk. Then used the old parity drive to replace a smaller, older disk5. I'm now getting SMART errors on disk5 (the old parity drive). I ran the extended test, but I'm not familiar with the errors enough to know if I should be concerned or not. Lots of "power-on lifetime" errors and it's a WD drive, I heard they get a lot of errors that other drives do not. My biggest concern is being able to rebuild if any drive fails. Tonight I'll probably scatter all the data off disk5 until I know what the disk needs. Any help is appreciated. extended-smart-test-disk5.txt doctorhands-diagnostics-20200427-1703.zip Edited April 28, 2020 by 1trkmind Quote Link to comment

(SMART overall-health self-assessment test result: PASSED) Are you saying that if any individual test component fails, the entire disk is bad? Quote Link to comment

1trkmind Posted April 28, 2020 Author Share Posted April 28, 2020 Thanks guys. Unraid is so picky compared to windows on disk health 😉 Quote Link to comment

1trkmind Posted April 28, 2020 Author Share Posted April 28, 2020 I guess it's time to shuck another 10tb WD Easystore. Quote Link to comment

Unraid is so picky compared to windows on disk health 😉 Windows only alerts you to an issue when there is data attempted to be read from a bad spot. Even then there typically isn't an error shown, you have to dig through the logs to find it. Unraid uses the entire disk capacity for parity protection, so any disk read error can cause issues rebuilding another failed disk. Windows will happily continue to use a disk until it dies completely, sometimes with no indication you are in trouble until you get a failure to boot. I have worked on countless machines where the users would have much rather gotten some warning than be told their only option was to send the disk away to a clean room recovery center. Windows leaves you blissfully ignorant of a bad situation. 1 Quote Link to comment
