I am new at this. when you burn CD and only use say 30% of disc space.....is there anyway to go back at another time to add additional information to the CD? The remaining 70 %

Everytime I try to go back and add more music it will not let me do this.

Thanks

If it is a regular CD R you cannot ever write back to it after you have burned something onto it.

On CD RW discs you can write over what was previously on the disk or add a few files to it.

I hear that CD RW can only take a couple of reburns before they do not work anymore...is this true?

Thanks for your help. How can I also see if I have double layer recording for DVD's

If you want to write to the disc and be able to add more to it later, you have to do it as Multi-Session. Nero Express has a tickbox for this. XP also supports this technology for CD-R's.

If you don't write to the disc as multi-session when you first write to it, you can't change it to multi-session later, nor will you be able to add anything else to it.

Audio CDs are the exception rather than the rule; for an audio CD to be playable it cannot be multi-session, otherwise you'll have a hybrid disc that no player on the planet will be able to do anything with. Nero will not let you make a multi-sesion audio CD for just this reason. Therefore once it's burnt, that's it. All you can do is rerip the files and make a new disc.

CD-RWs, quality pending, can in theory last as long as regular CD-R's. In reality because the laser of the CD Writer is "attacking" (for want of a better word) the data side of the CD every time you add to or remove from the disc, eventually the surface just wears out. The average CD-RW lcan last around 1000 rewrites, give or take a few hundred either way and how the media is handled.
