I had tons of pictures, but then all of sudden they disappear. I have a 2 GB memory card, but apparently I didn't format it. So I connected my BlackBerry to the computer and did a disk-cleanup like the error told me too. There reason why I didn't format is because I want to find those pictures! Now here's the weird part.
When you open up BlackBerry in mass storage data, you see folders like video, pictures, and whatever. My picture folder is not a picture folder anymore. It's just a file. Everything else is fine though.
Not only can I find those tons of pictures, I can't save any new pictures to my folder.
