December 18, 20223 yr Hello Smart folks, Yesterday, I was transferring a whole bunch of linux iso's from my cache to my arrary when I got notified of disk read errors from my disk 1 (14tb, 9tb used, 4 months old). I stopped the array, ran a short SMART test which came back clean then an extended SMART test which just finished, also clean (almost 20 hours in). Here are my diags and my disk 1 smart report. Is this a replace-drive-kind-of-thing? Or how should I best proceed? Thanks! 520unraid-diagnostics-20221218-1414.zip 520unraid-smart-20221218-1415.zip
December 19, 20223 yr Community Expert It's not logged as a disk problem and SMART look normal suggesting a power/connection problem.
December 19, 20223 yr Author That sounds like best-case scenario, right? I did a system shutdown (plus, unplugged the power) and started it up again but disk still had the red X. I tried "clear stats" but that didn't remove the X. Is re-build the right step?

December 19, 20223 yr Author Full transparency...I started a re-build of that one disk last night after reading other threads..... Followed these steps: https://wiki.unraid.net/Manual/Storage_Management#Rebuilding_a_drive_onto_itself Currently at 49.x% 520unraid-diagnostics-20221219-0841.zip
December 19, 20223 yr Community Expert Recommend swapping/replacing cables/slot to rule that out if it happens again to the same disk.
January 1, 20233 yr Author Reviving this thread today (Happy New Year!) as my drive again spew out some errors and is now disabled (sector errors?). I had swapped the sata data cable with another drive previously so I think we can rule that. RMA? 520unraid-diagnostics-20230101-0026.zip
January 1, 20233 yr Community Expert Still doesn't look look a disk problem, though it could be, but I would first try connecting that drive to the onboard SATA ports to rule out any controller compatibility issue.
January 1, 20233 yr Author Would it make a difference to know that I have another disk of the same male/model/size that I bought at the same time that is connected in the same way? (Hba) which is not experiencing errors Edit 13:15local: I changed the sata data to the mobo port (away from the hba). I also swapped the sata power cable with a different drive (am using 1-2 sata power splitter). Edited January 1, 20233 yr by Shu
