I noticed that my unraid is saying there is no flash.  I attached a new blank hdd to the computer but it never showed up in the array, so i was going to reboot but thats when I noticed that the message appeared. I removed the disk, could someone help me determine if a reboot will be ok to bring up the array?

It could be that flash is going bad, is there something I can do to prepare for a new flash drive so that i do not lose my config? 

diagnostics are attached.

Thanks in advance.

Flash drive issues since the 25th, power down and try a different USB port, ideally USB 2.0, if issues persist replace the flash drive.

Thank you for your response. 
it gave me the confidence to reboot.

I rebooted and the flash drive mounted successfully
