Yes, you are correct. If the data is sensitive then snap the disk into small pieces or score the 'label' side to make it unreadable.

CD-R (& CD+R) disks are designed to be written to once and, as such, are a good way of keeping a (relatively) permanent copy of data but they are no good for use as a 'use many times' medium, for that you need the ones with 'rw' at the end (for 're-writable'). The same goes for DVD and Bluray disks.

Once you have written to a CD-R disk you can only (in some circumstances) add data to it, you cannot over-write or erase the data already on there - the ones you can do that on are CD-RW. If you want to remove the data from a CD-R the only way is to physically destroy it

Yes, that is quite normal for a CD/DVD-R or CD/DVD+R. Once the space has been used it is gone.

Always pop back and let us know the outcome - thanks

Thank you for responding. WELL, that is a bummer!!!!. You mean physically "toss" the CD-R in the trash, RIGHT?

I did put the CD-R's (three of them) in my system and chose the format option and it appears that all the info is gone. However, when I try to put it back in it says it has data on it. So, If I understand correction the data just sits there and cannot be removed. Again, Correct?

Thanks for your time. Carolyn S.

When you delete the data on a CD-R it only prevents it from being immediately visible. It is actually still there and can be re-read with the right tools.
