They said on one other site that memory cards of 2GB need a card reader that is compatible with larger memory cards.
Hye may be its damaged! i will advise you to try connecting it to another pc! or Card reader and see if it works!
so i can have conon camera and the 2gb memory card i have always used it and it worked good last night i came i took bunch of pictures on my camera then when i took the memory card out put it to my computer like i usually do it wouldnt open up the i put it back in my camera it said memory card error and then i look at my canon camera i put the memory card back in under format it says 1.5gb used out of 1.7gb is there anywhere i can go so they can fix the memory card or transfer my pictures somewhere
