June 26, 20233 yr About a week or so ago I noticed my parity disk was disabled so i unassigned it/reassigned and got parity to rebuild successfully. I logged in again today and noticed it is disabled again. Need help finding out what the cause is, I attached my diagnostics file. looks like i'm getting a high number of udma errors but it seems completely random when they happen and they happen in large groups. running 6.12.1 unraid-diagnostics-20230626-1321.zip Edited June 26, 20233 yr by Lygris add details
June 27, 20233 yr It's not logged as a disk problem and there are a lot of UDMA_CRC errors, start by replacing the SATA cable.

I can give it a shot, the cables are the SAS to SATA breakout style and i'm running all the disks off an hba card. The cables are only a month or 2 old but I'll replace it today and see if a rebuild completes.
