DVD-R disk Problem

I have a good amount of pictures on a DVD-R disk that all of a sudden will not come up. No folders or files appear on the disk. Is there some way of retrieving the pictures from my computer hard drive? At one time all the pics were on the computer hard drive prior to transfering to a disk and deleting from my computer. Lots of memories, hate to lose the pics. The disk shows that there is some used space, 1.3 GB out of 4.7 GB. but can't view anything.

Thanks

Go HERE (http://www.z-a-recovery.com/) and download Zero Assumption Recovery. Install the software and try to access the DVD. Let ZAR search the disk and recover the files.

Same problem as your supposedly +R?

Close the session. Just like I'm going to do to this post, don't double post.
