5 parity errors that will not go away.

[Baregills]

I am a new user and since the beginning I have encountered repeated parity errors, five of them each time I run a parity check. I looked here in the forum and found others having similar issues, but could not identify anything applying to my configuration.

Assuming that one of my disks may have an issue, I replaced the drive that I identified as the likely culprit. 

This changed the result of the parity check, but it still gave five errors but now at different places on the drive.

I ran the check twice on each configuration (output included here).

I'm struggling to know what next to try.parity.rtfparity.rtfparity.rtf

Have you ever run a correcting parity check?   If not then you will keep getting the same errors until you do.

[Baregills]

Thanks.

Yes, I selected correcting check.

I have done another run since my initial post and this clearly shows that the error was corrected yet returned for the next (final) run.

What disk controller do you have?    I seem to remember something like this happening with Marvel based controllers.

[Baregills]

Yes. I looked at this but I don't have a Marvel controller.

I'm going to try again hoping for something different:-)

Perhaps you should post your system's diagnostics zip file so we can see more about your setup in case that sparks an idea in someone's mind.

Thanks, but I think the angels are with me. I came upon a post discussing a similar (but not exact) problem somebody was having.

They developed the idea that forcing a write of some data to the suspect drive, the issue could be resolved.

The logic of this eludes me, but such a simple action was worth a try.

And voila, the parity was clear and my concerns gone. (I am however not too keen on deleting that data I wrote - just in case).

I appreciate your help and suggestions which I will bear in mind for the future.
