Well, I've got lot's of experience with CD-RW disks, and all of it BAD.
My personal experience with RW's is that they are not reliable and may not even be readable on any drive except the one that wrote them.
That alone, makes them almost useless.
SO, why spend a lot more money for a disk that's not reliable?
CD-R disks are very reliable, when used with a properly functioning CD burner and are very inexpensive too. And, I'm told the average disk will last for about 30 years.
There are countless CD/DVD burning programs available. Many even FREE!
My personal favorite has always been the World-Class "Nero".
It will do everything a CD burning program should do and does it well.
However, even Nero can't compensate for a malfunctioning CD burner.
I hope this has been somewhat helpful
Cheers mates!
