Looking at Pegasus 12

Freshly formatted on what OS?

My guess is that the format isn't the issue and you have a broken / unseated cable. The whole format issue is what you need to dig through first though. There *are* well known issues in that regard.

I formatted SD cards with windows 10. I tried switching cables around today and making sure they were seated correctly. Still same as far as info screen says sd card inserted and next screen says no sd card. Augerpro suggested we try and reformat cards one more time. Would you recommend a different OS to format?
