Unsure of issue: "One or more devices experienced an unrecoverable error"

That should be easy. Do a fresh install of FreeNAS 9.3, then import your pool. You'll have to resetup everything, but your data will be there and you'll just need to restore redundancy and do the actual FreeNAS setup after that.

Ha...so I misused a couple words "Should I just be getting a new USB stick and installing a new version of FreeNAS?"
And that's why you were confused why I was asking about the new USB stick. I see. Precise wording is important, ay? Lol
I should have asked, "should I just install a new version of FreeNAS".
And, while I may have been lucky...it is correct at least that installing a fresh of FreeNAS would clear up the GUI error.
See, I'm not that crazy!
