Hello there, For almost a week I have been experiencing some trouble with my 600D when using my 64GB Kingston SDXC card... my camera seems dead if i don't use it with a autoexec.bin with it.
I used the steps on the forum to disable bootloader and uninstall magic lantern using another card after this started happening then formated the card.
If i turn on my camera without a card, it boots ok... If I turn on my camera with my 32BG SanDisk SDHC card, it boots ok... If I turn on my camera with my 64GB Kingston SDXC card, it doesn't boot at all... looks like there's not even a battery on it... When I perform a format without the "quick format" checkbox ticked on the PC(can't on the camera), I boots ok and looks normal... then stops after I take the battery off and put it on again of perform on camera format.
I suspect that my wife took off the card too soon and formatted the card after it would not open on the PC without uninstalling magic lantern(even though she said she didn't).
When I use the blink test from here it boots ok again!
Is there anything I could be missing?
sorry for any english mistakes, it's not my mother language.
