parity (WDC_WD40EFRX-68WT0N0_WD-WCC4E0707572) has read errors

 

If the disk has not been disabled, then unRaid has successfully rewritten the contents of the offending sectors back to the hard drive. It would be a good idea to look at the S.M.A.R.T. Attributes for the drive in questionBegin Investigation Here:

SMART looks fine, but that doesn't always mean there are no disk issues, I would replace/swap cables and if the same thing happens again replace the disk.
