adminmat Posted August 2, 2023 Share Posted August 2, 2023 (edited) Hello, I got an email alert about disk read errors that popped up during a Parity check. Shows 336 errors on one disk. I'm not sure what this means exactly and if I should replace this disk. (Disk 1) I know this question comes up a lot but I don't really see a thread with a solution / conclusion. Thanks for the guidance I just ran an Extended SMART test on the disk and am attaching my Diagnostics. Edited August 16, 2023 by adminmat Quote Link to comment
adminmat Posted August 3, 2023 Author Share Posted August 3, 2023 If anyone has a guide on how to diagnose this issue I'd appreciate. Is this in the unRAID manual? Is this a cable issue? Is there a way to tell if the data is corrupted? Quote Link to comment
JorgeB Posted August 3, 2023 Share Posted August 3, 2023 It's logged as a disk problem, run an extended SMART test on disk1. Quote Link to comment

I ran the Extended SMART test before I posted this thread. Here is the report. Thanks. Edited August 16, 2023 by adminmat Quote Link to comment
Solution JorgeB Posted August 3, 2023 Solution Share Posted August 3, 2023 Test passed so disk is OK for now, replace/swap cables to rule that out and run another check. Quote Link to comment

Ok so I'll change the cables and check everything physically. Then run another Extended test? Should I reboot? Quote Link to comment

Swapped the SATA cable. Ran a parity check that completed with no errors. I should be good for a while then, right? I was opening and closing a cabinet the server sits on during the last parity check. That jostling could have caused it? Quote Link to comment
