1st non-correcting check detected the same 4 errors. 2nd correcting check corrected the same 4 errors. 3rd non-correcting check detected 0 errors. So it seems like the RAM was the issue. I'll run another check in a week or two to confirm. Thank you very much for your help tracking down the problem!

I ran memtest for more than 24 hours and no errors. I've swapped out the RAM for a spare set I had and running a new check. What we hope to see is the same four sectors from the last check?

Is this the sort of error memtest should pick up? So far it hasn't picked up anything but I'll leave it running for 24 hours. Is there something else I can do to nail down the cause? Is the best approach from here to replace the RAM, run a correcting check and then a non-correcting check to make sure the problem is solved?

I'm quite new to unRAID so any help you can offer would be greatly appreciated. Logs are attached. My first quarterly parity check detected some errors (3). Things had been running smoothly until that point with mostly new hardware. A faulty UPS meant some unclean shutdowns so I thought that may have been the cause. I ran a correcting parity check which picked up five errors. Next I ran another non-correcting check which has picked up four errors. The sectors seem to be the same? Hard drives are connected directly to the motherboard. I have - run extended SMART and all disks passed - currently running memtest86+ but clear so far after a few hours - switched the SATA cables to new ones Assuming the memtest is clear overnight, what should I do next?
