Yes I formatted the card with my computer and camera
Hi Bob, thank you for your reply. I formatted the card with my camera..which still allowed me to take pictures...but every once in a while..i would get the message "This card cannot be used" After I formatted it in my computer...the message disappeared. At the same time I cleaned the contacts with Dust Destroyer. Things seems to be working fine.. This morning while taking pictures...I get the above message when I tried to turn off my camera...I then removed the battery.... checked and only some pictures appeared.
Just wondering...why ..this is a new card..I bought it with my new camera...My friend also bought the same camera..and the same card and she does not have any problems....Thanks.
