i have a blank cd, how can i add things back on it

i forgot to add something to a blank cd and now it wont let me add it back, how can i overcome this situation

You won't be able to unless the cd is a CD+-RW, If it is a CD+-R it is impossible

is there anyway to add things back to a Cd-R,



any material on the internet or software



why is it impossible



surely someone can hack into the cd to make this possible

nope its not possible with CD-R, the disk is "closed off" once its finished and cant be edited in any way.

You can burn another CD-R of the one you are wanting to add to, and then add the new content before finalizing the CD. Otherwise, no can do. Just the nature of R vs RW.

the actual term is "finalized", once a disc is finalized the burning software writes the "lead-out" onto the disc after the data you just added. Nothing can be added after this point.... its physically impossible. CD-R discs are once use only, you burn to it and then you either throw it out or you archive it or use it. You cant add more stuff to it, thats what they invented CD-RW discs for. These act as huge floppy discs (theoretically) and can be written to and deleted from many many times (not infinite though).... If you used a CD-R disc then nothing more can be written. There is also no way to "hack" a CD, lol, its not gonna happen, and anyway, for the price of a CD, like 15p, why are you worrying so much, just make a new CD which includes the thing you left out...

Thats not entirely true. If the CD was burned as a multisession, then content can be added later on. But if it was finalized then you're right, its impossible.

well, yeh, hence why i said right at the beginning "IF IT WAS FINALIZED"

I thought only RW's could be multisessioned.

No, only RW's can be erased. Normal cd-r's can be multisessioned.
