May 28, 20224 yr Hi, While copying new data to my array, one of the drives became disabled. Looking at the logs, I saw multiple "I/O error". See the Diagnostics file attached. After stopping the array and starting it again Unraid mounted the drive but did not re-enable it. Also no I/O errors right after mounting starting the array. So I decided to follow the guide of rebuilding the device to itself, because with the help of the parity drive, all data were there. However, just after 0.3% of progress, I got the same I/O errors again and the re-build process stopped. Do you have any further advises how to proceed? Is the device defect? Do I need to perform any other steps before adding back the device? Thanks, MiNe zentrale-diagnostics-20220528-1036.zip
May 28, 20224 yr Author After a reboot of the system and checking the cables of the disk, I'm able to read out SMART and see these errors. I guess, this doesn't look good for the drive... The UDMA CRC errors are there since long time already, but "Current pending sector" and "Offline uncorrectable" are new. Edited May 28, 20224 yr by mine
