Hello Steez,
The Event shows that it had an Unrecovered error, However the Disk may be still healthy. We need to check the logs on the number of unrecovered errors ,
If this event is logged for the same disk more than five times in one week, and the indicated
disk is running the latest firmware, replace the disk with one of the same type SSD/Enterprise SAS.
Hence analyzing the latest logs will let us now the actual health of the drive.
Hope this helps
Regards
Shaan
