aTV Flash does have issues with some USB drives, especially ones bigger than 2GB. Do you happen to have an older one that is 512MB - 2GB? You can see compatible flash drives here: http://forum.atvflash.com/viewtopic.php?f=4&t=68 If that doesn’t seem to be the problem then let me know and I can try and help further.
I HATE saying the same things over BUT it looks like MANY of us are having the same problems. Where is ANY SUPPORT? I am a Mac user for over 6 years and had NO trouble created the boot stick… I made one using a 4gb DaneElec AND a 1gb Kingston Data Traveler . Both sticks had NO trouble during the stick setup procedure. They BOTH completed successfully.
HERE is the TROUBLE…
BOTH sticks… I placed in the USB port of the ATV while the power plug was OUT. I then reinserted the power plug. The Dane stick reboot did totally NOTHING, the ATV started as usual as if that stick was not present. The Kingston stick, The ATV started then hesitated foe a split second on a green scree blip, then resumed again as if no stick was present. So here are 2 different BRAND sticks, HOW PICKY can this be?
So what is the solution? Now I have 2 USB Flash Drive sticks PROPERLY LOADED with the atv software and it simply will NOT work. I have looked at the boards and even tried the disk Utility as suggested partitioning each stick TWICE. Again… I am left here with a $49 bill and NO product to speak of… Is THIS MY FAULT? I have entered this agreement in good faith, I read the contract, I PAID the fee (Legal consideration), so now what is atv’s end of the agreement? I am SURE they would much rather HELP and make everybody happy. So please, if you are reading this… H E L P !
