@sugarfree THANK YOU!
this is solved
never would have thought updating the retro-pie set up script was how I lost the external drive loading.
i got busy for a few days, was wondering what to do, this am I was able to get on the forum, seen others having same issue after the update of set up script, then remembered "I did that too!" I seen it's been fixed and re did the update, now i have the drive loading again.
thanks for taking the time and adding this info!
also thanks to all others who commented advice
SOLVED!!
