Message Unable to use card.

Hi,
I've seen quite a few problems regarding memory cards recently.

Most of the time it is the card at fault as it just does not store data anymore. I haven't yet determined if it's time/ use/ temperature or handling which is causing the faults.

Can you describe what happened prior to the card not working as it may help solve future problems?

Some older cameras cannot use the newer - larger cards (even though they fit), and some cards won't record panoramic data.

Try resetting the camera first. - Remove batteries and card for 10 minutes, then reload them.
If you normally use a PC to download the pictures, see if you can access the pictures from there.

If half have gone, or are corrupted, it's time for a new memory card. Films were 1 shot, now cards only last a few years, but still saves you £ / $ in the long term.

If the new card doesn't work either, you will need to re-install the camera software (or Driver). This should be on a CD or you can go to their website to download it free.

Thanks for using Fixya! If this solves the problem, please rate as such. Thanks.
