Formatting DVD-R

[Teneesh]

I'm tring to erase data from a DVD-R disc. But when I select the erase disc option, there is no option for a DVD-R. Can anyone help?

You can’t erase a DVD-R, you need DVD-RW for that.

DVD-R is a WORM, Write Once Read Many, format.  It's a one and done affair with writing in ImgBurn.  DVD+R and DVD+/-R DL are the same.  As LUK said, you need DVD-RW or DVD+RW for erasure.
