part delete cd r/w

can anyone tell me in simple terms why i can delete content on a cd r/w but not edit by deleting some of the content?

Because the content is contained within "lead in" and "lead out" data (a bit like parentheses in writing) and the erasing protocol will not permit partial erasing of data within these parentheses.

....I think !

You can only do it if you Format the CDRW disc with Packet writing software

If you have created a mutisession CDRW I think you can create a file by the same name which would then overwrite the existing file name, the file would still be there I hasten to add its just that you would be no longer able to see it, you would just see the new one with the same name, the file would be there until you formatted the disk again.

I think this is correct but no longer use CDRW I find they are just not reliable enough. Since CDRs are now so cheap I just create a multisession disk and keep adding till its filled. If it is very critical info I make 2 copies, such as my photos.

DVD RAM looks like the way forward on this sort of thing any comments/

Ray - I use RAM quite a lot now, but I also routinely use standard DVD-RWs that have been formatted with DLA so that they behave like a hard-disk partition. That's the most convenient for me, as RWs are faster than RAM (in my drives at least). The projected longevity of RAM could appeal if you want long-term archival.

well i apologise to the more knowledgeable posters but most of the answers are well over my head.
