I was occurred this problem last month in my blackberry curve 8520 when I was just attached to my laptop. At that time by mistake I press yes and my all data is loss. So, I understand how much it hurts when we lost the data. I will tell some ways to protect your data and how to come out form this problem.
You can reboot your phone and check problem is occurred.
Remove the Memory card and reinsert it again. Maybe card is not inserted properly.
Use the disk repair options with the media card in the Blackberry.
If you run Blackberry device OS 5.0 you can run the device repair application. It will address the media card, as well as internal device memory file system.
You put this card into a different BB and see problem occurred with this phone also.
You put this card into a PC by card reader and take backup data and format it.
Use the Windows or MAC disk repair tools to repair Memory card.
I hope any one of them solves your problem and if you continuously occurred this problem then contact to your nearer blackberry store. I advise you that you obtain a known-good card (good brand) . Always frequently take back-Up of your card because that kind of problem is not coming with prior warning. This is best defense to protect your data.
