Recently added drive failure

[fysmd]

 

Unraid v 6.7.0

diag attached and drive ogs below.

 

This drive is not very old, only 6.3 weeks of runtime.

Nothing logged (telegraf) into Grafana from that drive seems to indicate it going wrong.

 

Could this be a simple HDD failure and nothing to worry about?

Disk looks fine, looks more like connection issue, suggest rebuilding after replacing/swapping cables/slot to rule them out if the same disk fails again.
