I am using a 2TB external USB drive as external storage for movies. It worked for some days, but now my Apple TV is no longer booting when the external USB is on. The drive is fat32 and I got Smart Installer installed.
When I try to turn on the Apple TV, I get the Apple logo on the screen. It stays for some seconds, then it disappears twice for a glimpse. Then it stays on the screen.
Thanks for your help!
