Well, after succefuly burning my first game, i there was like 2 copies that failed (because of me) now i made 3 more game copies and i found out they all failed i was wondering can i write over them to save discs?

those two discs are now only good for coasters.

Yes! You can!

Go to your local store, and buy a sharpie, or other felt tipped pen/marker.

Go back home, and write anything you want on it!

-/+ R is ONE TIME ONLY

-/+ RW is MANY TIMES

You can also apply a blank label to the disc and write anything you want on it.

You can only write over a DVD-/+RW

Is there any difference between -RW and +RW?
