Thanks for any help.
The erase a cd/dvd in windows 7 pro doesn't seem to work for me.
So I use a program called "erase dvd". After erasing with this
program I go to "computer" and right click on DVD.
Then I right click on properties. Most of the time it shows as not
having erased the dvd. By shutting down the computer and
restarting I then get the correct figures.
What am I doing wrong?
