blanking a dvd-rw with dvd+rw-tools

[Pablo Rodriguez <oinos@web.de>]

After having no success with cdrecord.prodvd, I have tried to blank a 
Memorex dvd-rw. The blanking process seemed to be fine, but I get the 
same mediainfo before the blanking than after it. Bellow you have the 
result. Of course, I didn't get growisofs (through k3b) to burn any 
files on the dvd. Is the disc physically damaged?

Thanks,


Pablo
