Thanks for response, I just wanted to check that was ok. The server is a new configure and all the drives are new and in good condition so figured that the data would be good. I just didnt want to re-run parity and end up embedding bad data in parity. I do have (and will retain) a backup of the files, just figured if i had to fix a problem, id rather do it now than some point in future To be 100% certain, I tick the box "write corrections to parity" then run a parity check and wait for that to complete
