Micro SD Krzr Won't read pictures

Question

I had a Micro SD in my Razr. I have a lot of pics and videos on it. I bought a Krzr and transfered the SD. It Recognizes the SD, but it won't show that there is any files on it. I put it back into the Razr, and it still shows the files there. Any idea why my Krzr recognizes the SD but won't read any of the files on it?Thanks
