Partially burnt DVD

Hi,
I started burning a DVD and after approx. 1GB it failed. Now, there are still 3GB untouched on that DVD.
Is there a tool that can analyze the DVD and close the session and offer me to use the rest of the disk (i.e. a new blank disk with 3GB capacity)? Both Windows and Linux tools are of interest.

TIA,
NGC

Nope. That disc is trashed.
