The only errors I see are CRC errors, and these are not drive issues, but connection issues (typically related to power or SATA cabling).

Occasional CRC errors are not an issue as they merely trigger a retry of a transfer. Note the CRC count never resets to 0 - you can only stop it from increasing. If you click on the orange icon against the drive on the dashboard and select the ‘acknowledge’ option from the menu displayed then Unraid will only notify you again if the count increases.
