Unfortunately, my parity disk disabled. Tried to rebuild, but yet again disabled. Any thoughts from the log whether this is a disk or cable issue. The disk is just a few weeks old, so hope that this is not already a warranty case. Log attached. Thanks for your help!

SMART looks fine, but you can run an extended SMART test to confirm.

Thanks. Let me do this. I did the quick SMART before, which showed no errors. I didn't succeed the extended one to complete, but this may be a cabling issue. Let me give it another try and report back.

The extended test is performed inside the drive, so it doesn't require a working data SATA cable to be able to complete.

Some drives even manages to restart the extended test if the drive gets powered down in the middle of the test.

 

Unless some software aborted the extended test, it might be meaningful to also take a closer look at the power cable for the drive.

Thanks for your note. I keep on having these issues related to "cabling" since starting to use Unraid some years back.

 

I could consider changing the PSU or buy an UPS if you think that this may be a potential source of the issue? If so, any suggestions on an UPS? I have a 850W Corsair PSU, so would need to be able to support this.
