I recently swapped a broken, older disk for a new one. Now, during the rebuild process another disk had read errors and was taken offline. I got the email notification a few hours ago.

 

From what I've seen on the disk itself there seems to be no SMART report available from the disk.

 

I'm not very experienced in troubleshooting issues - I'd be thankful for anyone that could check on the diagnostics and help me track down the issue.

 

Thanks

 

EDIT:

 

This was the notification for reference
