xtrips Posted March 8, 2021 Share Posted March 8, 2021 Hello, One of my HDDs, a 7 years old 4Tb WD Green drive suddenly showed some 30 reading errors while building parity. Of course after the Parity successfully finished I replaced it with a new one. But in doubt I ran an extended test on the drive using WD tools. After some 7 hours the extended test showed a well green lit Pass. What does it mean? Can I trust the WD tool extended test? Does that mean the drive was fine all along? Maybe I had a cabling problem that is now solved? I just finished transferring my Unraid to a completely new machine..... Quote Link to comment

xtrips Posted March 9, 2021 Author Share Posted March 9, 2021 As I said, the disk has been replaced already. Will the log help in that case? In the meantime my UPS has died so don't pay attention to the latest events. The disk that has been replaced is #5. novanas2-diagnostics-20210309-0956.zip Quote Link to comment

I don't have it but the extended test showed everything in green. My question is is their tool (WD) reliable enough to decide that this disk is good in the end? Did anyone have a similar experience? On the other hand can anyone propose a method or tool to definitely decide if this disk is good or not ? (in the meantime I had another one exactly like that from another machine so that makes two) Quote Link to comment
JorgeB Posted March 9, 2021 Share Posted March 9, 2021 I would prefer to see the SMART report but if the WD extended test passed the disk should be OK, at least for now. Quote Link to comment
