August 3, 20196 yr I'm having repeated issues with a brand new disk being disabled. Adding a brand new 10tb disk to my array to replace a 4tb one that was failing. Transferred all data off the failing drive while the new one was being pre-cleared. Swapped the new one in and the initial rebuild/parity check passed ok. A couple of days later I noticed that the new disk was disabled due to write errors. I switched to maintenance mode (didn't really see any smart errors) and ran an xfs_repair. Restarted the array and parity passed. After a couple of days I see the drive is disabled again. Swapped the out the sata cable for good measure and repeated the repair. This time it failed with a long list of read errors.

Appreciate any assistance! diagnostics-20190802-2322.zip WDC_WD100EMAZ-00WJTA0_JEHLSVTM-20190802-2000.txt
August 3, 20196 yr Community Expert Disk looks fine, try swapping it around with a disk on a different controller.
August 3, 20196 yr Author Thanks, that's good to know. I switched it from the motherboard to a sata controller. It's rebuilding now, fingers crossed that fixes it.
August 4, 20196 yr Author Rebuild just finished with no errors! I'm hoping it lasts this time lol. Thanks for the assistance!
