blanking DVD+RW

[Claudio Discepola]

Hi,

  I have a quick question about blanking a DVD+RW.  It seems that even
after I run the "growisofs -Z /dev/cd0=/dev/zero" command the "Disc
status" is still seen as "complete" instead of "blank". 

  Is there another option I should have put?  (doc on growisofs didn't
mention anything).

Thanks,
Claudio
