What I would like to accomplish, is to burn an image(.ISO,.BIN, etc...), leave the session open, and then to add more files to the CD(MS Office Image, then all of my docs, & spreadsheets). I can do this using Alcohol 120%, leave the session open, and then add tracks with Nero. Everything works fine when I do everything with XP Professional. However, if I try to READ the final CD on ANY OS(Win 2000, in particular) other than XP, it doesn't think there is a CD in the drive. Does anyone have an explanation for this? I have tried all different modes, and options in Nero. Is there any other SW that will allow me to continue an "open" CD that already contains an image? CDRWin doesn't let you do that. Thanks in advance to anyone who can help!
