This is a complete newbie question that I'm almost embarrassed to ask. I just got a cd-rw drive for the first time and I thought I'd make a backup of my stuff on a rw disc so that I don't have a collection of cdr with my stuff, just one that I update. I used toast to burn the stuff. I chose "write session" but it looks like I can't delete stuff off it. I think I can write to it again, but I thought it was supposed to be like a floppy in that you could delete and rewrite it. Was I wrong or did I just do something wrong? TIA.
