BB Torch :: Device Memory Cannot Be Read - Try To Repair Or Format

Last week my blackberry torch, whose battery life has been rather poor, cut out due to a dead battery. When I charged it and switched it on, my wallpaper had change and I thought weird but whatever. Anyway, I found the next day, when I tried to take a picture of my kids, that all my photos are gone and I can no longer take any pics coz it says that the memory is full, even though the media says 'o photos'. I am gutted, but have found the following message on my storage menu ' device memory cannot be read. try to repair or format'. I've tried to repair it but it fails, and I am holding on to the hope that my photos are still in there, so want to avoid formatting it until the last possible moment. I am desperate for the pictures, there are just too many of my kids there to have to lose.
