July 5, 20224 yr Hello, I'm not really used to unraid, and I just had an 8TB drive go disabled after, apparently, 512 read errors. I got this notifications : - "Array has 1 disk with read errors" - "Alert [TOWER] - Disk 2 in error state (disk dsbl)" I've stopped the entire array immediately. Some of my disks begin to have udma crc errors recently (including the disabled disk 2), I suspect the poor-quality sata cables, which i've planned to change. Can someone please review diagnostics and provide any insights? (Sorry for my poor English !) unraid-rb-diagnostics-20220705-0826.zip
July 5, 20224 yr Community Expert Solution Yes, it does look like a power/connection problem, disk 1 also showing similar issues, replace cables and rebuild.
July 5, 20224 yr Author Thanks for the answer, i just have to restart the array, and let the system rebuild ?
July 5, 20224 yr Community Expert After replacing the cables start the array and check that the emulated disk is mounting and contents look correct, then you can rebuild on top: https://wiki.unraid.net/Manual/Storage_Management#Rebuilding_a_drive_onto_itself
