This is probably a silly question, but my iMac is my first new computer in 7 years. I have only worked with floppy disks up until now for backing up my Quicken data. Now that I only have a superdrive, how should I back up my info? CD-RW, CD-R, DVD-R, etc. If I don't want to rename my backup data each time, don't I need an RW? If I do, do I ever "burn" the disk? I tried that, and now I cannot write to or even open the data on my CD-RW. Thank you.
