when u do a one to one copy of a multi-session disc, either CD or DVD, does it become one session???
It shouldn’t, but it may depend on the program you are using. For example, Clone CD or SwiftDisc will preserve the origirnal sessions. I have not tried that extensively on others.
There is another possibility. To ensure you to have only one session, you can copy all data on a folder on HD, and then burn the entire disc selecting “no multisession”.
