Iv'e got two SanDisk Extreme Class 10 SDHC 8GB memory cards for my GoPro. Ive used them and been deleting the footage from the memory card after I've uploaded it to save memory but now GoPro says memory card is full and when I check it on my mac it says there 8.2MB of storage left but Ive deleted all of the other files on the card so the card is now empty.
Cheers
