I cannot seem to make a working backup copy of an informational data disk that I have. None of the protection detection software out there can determine what it is, and neither alcohol or clonecd can make a working copy. I have noticed that the disk is multisession, and I am thinking that probably has something to do with it since I bet these programs are burning the disk as a single session. The disk only has 5 files on it, the autorun file, an excutable menu, and then three pdf files. Looking at the file sizes of these files, and the size of each session, it does not add up. There may be something else on the disk adding to the file size.
To make matters worse, after playing around trying to get it to copy, now the excutable is saying the original disk is also invalid.
How can I get around this multisession stuff?
