hi I have an sdhd card for pictures to view from mac to a projector ,, now the card was playing and I erased it on the disk utility on my macbook pro, now the projector doesnt recognize the sd card anymore,, what can I do? I tried to format it from the projector itself but it doesnt have the format button

Hi and welcome.

Pop the card into a camera (any model) and erase it there, that should do the trick.

Hi thanks a lot for your help, it worked, but now its gettin me another problem like it was doing before I format it on the mac , when I view the picture,the picture is not showing, its saying format error
