Here's what I use: XP Pro, XP's own burning "software", and a 24/10/40 Plextor. Here's what I want to do: Toss in a CD/RW disk with old data on it, and wipe it out or overwrite the data. This is for backup purposes... What's the point of using ($$$) CD/RW disks if I can't overwrite old backed up data with new data??? Does a man like myself need better software with more abilities than the built in XP burning software? Spankyou for looking and reading.
