I have a few questions about using CD-R and CD-RW discs with the native CD burning features of Windows XP. Is it possible to add new files and folders over time to a CD-RW disc? I'm having problems doing that. Sometimes it corrupts the files. Also, how do you tell XP the speed at which you wish to write to a CD-R or CD-RW disc? For example, I'm using 12x10x32 Plextor CD-RW drive with 16x Maxtor CD-R and 10x Verbatim CD-RW discs. Does XP know to use 12x for the CD-R and 10x for the CD-RW? Third question, would I be better off buying 3rd party CD burning software like Ez CD Creator or Nero for doing the incremental adding to my CD-RWs, assuming that's possible? Thanks.
