February 13, 201511 yr It's telling you that your parity information has never been checked, which is correct if you just installed it and built parity. Building parity reads all your data drives, and writes to the parity drive, but doesn't go back through and verify that the write completed, it just trusts the drive to do the right thing. A parity check reads from ALL the drives including parity and does the math to verify that the parity drive is correct. A non-correcting check just alerts you to any discrepancies, a correcting check alerts and writes the new value to the parity drive. Parity checks NEVER change information on the data drives, only updating the parity drive to match what is received from the data disks. If you have a failing data drive, a non-correcting check will give you the opportunity to investigate, while a correcting check could make it harder or impossible to recover the data from the failing drive.
