Lost images on DVD-RW
I put a DVD-RW in the drive yesterday and was a little grief stricken to find that of 633 images only 1/3 appear to be there. The remainder of the thumbs display a large red X viewed with FastStone Viewer.
And with Windows viewer
They were all there originally when viewed over two years ago. No damage to the disc and it has been stored carefully in a folder.
Are these images recoverable at all? How does this happen?
