help with write protect files

i accendentally made a DVD RW write protect and now i cant write on it is there anyway to undo this.
Thanks

 

How do you write protect a RW disk? I do not think you can. Is it a DVD+RW, DVD-RW, DVD-R or DVD+R?

 

Copy what's on the disc and reformat it?

 

Yeah it was a Memorex DVD+RW.

And i had used Nero Back it up and then i decided to erase it. So I used Nero's full erase and when I tried to copy another file onto the DVD it had said that the DVD was write protected. I wanna know if there is any way to sort of trick my computer into thinking that it is not???

 

And by the way what do u mean by reformatting it??????

 

HELLO ?!?!?!?!?!

 

Anybody??

 

reformat = erase the rw disc.

There is a glossary at the top of the page,
You can use it its free.
Along with that "search" box up there.
