I just bought a cd-rw drive. it's a btc 52x32x52 cd-rw. Now, i have the softwares to burn, but what kind of disks to I buy? I want to copy some data files (.exe, .txt, etc) from my hard drive on to a CD and transfer those files onto another computer (the other computer has a slower CD-R speed though). So, do I need to buy some blank CD-R disks? I also saw some CD-RW blank disks? Do I need to buy that? What's the difference? Plus, I also saw something like "48x CD-R blank disks" what does that mean? Does the speed of the blank CD-R or CD-RW matters?
