How do I reformat a write protected disk?

[sseehafer]

If you want to reuse a dvd, how do you erase a write protected disk?

Unless the DVD disk is a DVD-RW, it can not be reused.

On the bright side, blank DVDs cost about 15p (30 cents) each. Treat yourself to a few.

It is a DVD-RW. I put windows 8x64 on it, and now want to put x86 on it instead (for a different com). How do I format it when every program I use says it's write protected?
