Reformatted my hard drive yesterday and restored the factory image. Spent all this time making data backups to DVD-R's, and now the same drive that burned the fucking things won't read the files to allow me to copy back to the hard drive. Luckily it only happened to the ones that weren't all that important, but I don't get why it would write to the DVD but not be able to read it. It makes no sense. It shows the files in an explorer window and all, but it won't let me open them or copy them to the HD. Are these lost forever, or would a different drive maybe be able to read them?
