ReadyNAS 516 Degraded Volume
Just upgraded to firmware 6.7.5. Shortly after that my volume is listed as degraded. All drives are showing as healthy. Not sure which drive to replace. It is one x-raid volume. 5 disks. Only indicator I have is one drive is showing Uncorrectable Sector Count: 5 Pending Sector Count 5. Any ideas how I can tell FOR SURE which disk it is or what is causing the issue? Just videos so I can get them back from physical copies but I would rather not have to spend the time if it can be avoided.

You can check the channel of the device in disk_info.log, iirc it starts at zero.
Looks like it was device 1 or the 2nd bay of the NAS. I went ahead and made a backup first. After that I pulled the 2nd drive and replaced it. Array rebuilt and everything is healthy now. Thanks for the help guys!
I'm glad we were able to help.
