question about my external HD

for some reason my HD doesn’t show up on my appletv screen? 

Would standard protocol be to reinstall the last Flash?

Will this wipe my Internal HD clean?

Is there something I’m missing or not checking for???

 

tks for you help

I’ve had this issue with my aTV 2, but its a matter of making sure you have Shared that folder under every possible way from your computer, and gave the permissions.  Play with that enough and it should pop up.  It’s not the aTV.
