Memory Stick Problems

Hi, I have problems with my memory stick due I take some pictures and the preview in the camara don't show any problem, but as you can see in the attached files there are error. I think the allocation table is wrong. What I can do?

I think the memory stick has a problem in the allocation table.
Memory is a 4GB Sony


Thx in advance for any help

I would try a format of the card to see if that will resolve your issue!
