I had to reinstall Vista for a client. Before doing it, I backed up all her documents and iTunes files to CD, and all her pictures and videos to a DVD. Then I reformatted and reinstalled her OS and apps.
I took the CD, and was able to recopy her docs and music with no problem.
But when I put the DVD in, the icon switches from DVD-RW Drive to CD Drive, and I can't find any files on the DVD. Further, I get a popup box that asks me how I want to open the writeable media. So now I've got this poor girl's last two years of pictures, and no way to get them back to her.
I did not use any third party software to do the burn to DVD - just stock Vista. The DVD looks like it's been burned, and it did take about 40 mins to complete, so I do believe it copied the data to the drive. I just can't seem to get anything off, and this is the only copy we now have.
