I had posted a question in the Hardware forum which was partially answered, and has led me to this question: I guess I need to get some CD-R/W software, one that allows me to erase or write over data on a CDRW disc. This is for backup purposes, I back up important data once a month to the same disk, overwriting last months older data. So far I've been using the built in burning utility inside XP Pro, but it doesn't offer the ability to erase the disc contents, not that I've found anyway, so it seems I need some 3rd party software. Ok, now onto my question finally: Nero INCD (spelling?) was recommended and I want to know, does it use some method of data writing that only allows playback of the data while using Nero? In other words, can I write data to a CDRW disc, take the disk to a computer which doesn't have Nero INCD (?) and will that PC read the files perfectly? Then in the end, still be able to erase data or at least overwrite it back on my own computer with the Nero program? I guess what I'm asking is, once written, is Nero INCD (?) required to even read the files? If so, is there a better program you folks could recommend, which is not proprietary?
