Hello, I am pretty new to the Unraid / home server land and it has been only a month since I have setup a small PC with Unraid. 
My current setup is 1 Parity Drive + 1 Drive. Seagate Exos 14TB drives which I recently bought from Ebay refurbished.
I was successfully able to setup Parity and everything seemed to be working fine. In the last parity sync where I enabled 'write corrections to parity' I saw a bunch of error which I did not think about too much at the time as it said that it did not find any errors


But yesterday I saw that the parity disk has a smart error. Looking at the forum I ran both short and extended self-tests on the disk. Short ran fine but the extended keeps failing with 'Completed: read failure'.

Looking at the attributes this is what I see:

 

Attaching the diagnostics to the thread as well.skynetunraid-diagnostics-20240303-1954.zip

I don't know what that error is and searching for the error text leads to solutions which I don't think I am able to follow within the context of unraid or formatting it.

I saw one post (can't find it now as I read too many) that moving files using unbalanced somehow fixed it for them but that was on data disk so not sure if it applies to me?

All the posts I see here say that I need to replace my disk. Is there no way to recover this disk? Since it is parity disk can I somehow format it and rebuild the parity? Are there any tools that can overwrite the bad sectors on the disk to help?

Thanks.

Replace. 

 

The disk firmware has tested it and says it is bad

Thank you. Can I live without a parity drive till a new one arrives? I think I am still within return period for this disk
