OverWriting to a DVD-R

[dvd-alex]

I received some defective media a few days ago(blue blochy swirls on one side). I am in the process contacting the vender.

If I am required to return the DVD-R’s that I burned, but are partially defective, is there a tool that will force the drive to write all ones or zeros to the media so that sensitive data can be “shreded” on a DVD-R?

Thanks

Dont return the burned ones just say you chucked them out as they were no use…Or just tell them its personal data which only you want to see…
