January 2, 20242 yr Hi all, I've ben having issues with my Unraid setup for years. Constant errors pushing my disks into emulation. I was fed up with it and decided to start from a scratch. I've created a new config precleared 3 16TB drives: 2 for parity and 1 (for now) as data drive. The data drive precleared without any issues but the moment the array starter the first parity-sync I got errors! I've started the SMART extended self-test and it "Completed: read failure" (attached report). The only problem is that this drive has 26 hours on it and 16TB written (=preclear) ... I literally took drive I've never used (cold swap), precleared it and put into the array. This is some post-warehouse drive. Could the SMART be cleared? Is it possible the drive was mishandled in transit? Or am I simply unlucky? Thank you ST16000NM001G-2KK103_ZL2BD0A0-20240102-2203.txt Edited January 2, 20242 yr by Borys
