I have a Canon Rebel T3 and a Lexar Platinum II 8 GB SDHC class 6 card.
I can only fit about 180 photos on this card that are roughly 5 MB each. Unless my math is really bad, that's only about 900MB used, so I should still have 7 GB left - but I don't.
When I plug this card into my computer and dump all the photos off, it says it has 8GB capacity, but every time I go out to shoot photos the same problem comes up, and I'm limited to under 200 shots and then my camera tells me the card is full.
Can anyone tell me what might be causing this, and any suggestions to help resolve this issue would be appreciated.
