Ok so I have 3 spare drives I've never added to my array I can use what would be the best way to copy the info over to 2 of those spare drives?

How would I go about trying to copy the data over to other disk if they will not mount in the array would I be able to do it in maintenance mode?

Thank you for the input I deleted all the text files and uploaded the diagnostics zip.

I just recently replaced my disk with a new disk and I'm still getting the red x mark next disk 14 to it the other disk that was replaced I moved that to a new slot and it work fine now I have another disk with green ball next to it popping up as unmountable also when I start my array any help resolving this issue would be greatly appreciated I have a copy of my system logs thanks in advance. tower-diagnostics-20170721-0035.zip
