Just wanted to provide an update, I bought a new PSU, changed it over and the errors immediately went away and I've managed to do a full parity sync with no errors I kept all the other adapters and sata cabling in place, expecting to need to methodically change them out during testing, but it looks like it was the PSU all along, thanks!

Thanks, I'll have a look and report back. I've got 2 banks of 4 drives daisy chained on Silverstone sata power strips, could these be the issue, or could it be PSU related?

Hi guys, looking for some assistance. I logged into my server last night for the first time in over a week and noticed that one of my 2 parity drives was in an error state from over a week ago. I stopped the array, removed the drive, restarted, stopped, added the drive back and started, triggering a rebuild, which almost immediately failed. I checked the logs and saw that he drive has a load of read and write errors. The drive is fairly new and passed all the short test a while ago with no issues. The reason for posting is that I had something similar a few months ago and thought I had traced it to a failing HBA, which i replaced and all my problems went away. Could it be the same issue again? It feels too soon to be a coincidence. Any help would be appreciated, diagnostics are attached and the rest of the array has been performing fine tower-diagnostics-20251118-1902.zip
