Re: CR-R and CD-RW Issues

I began using CD-R disks for backing up my data files some months ago. I updated frequently and the newer files overwrote the older ones. Recently though, the system will no longer delete the old files on the CD-R. So I rapidly run out of space on the CD. What's happened?

So I went to Staples and bought some CD-RW disks, but the system won't allow me to write to any of them. I get an error message saying the disk is "not accessible. Incorrect function." Did I buy the wrong kind of CD-RW disks?

Any ideas about this behavior? Thanks in advance!

New files do not "overwrite" old ones on a CD-R -- what you see is just a trick called "multisession" that makes it appear as if they did. So basically you can write and write and write until the disk is full and then it refuses to go any further because it simply can't because it is full. As for the CD-RW not working, that could be any sort of problem. What sort of program are you using to write to your CD? Does it have an "erase disk" function? (don't get your hopes up, this applies only to RW disks which indeed can be erased). What is your CD hardware? If it has upgradeable firmware have you installed the newest version from the manufacturer?
