growisofs - burn the file again?
I am using growisofs to burn DVD's. After burning a file I do diff to see
if it was burned properly. If there is an error I try to burn the file
again using growisofs.
I think growisofs sees that the file is already there and does not try to
burn it again. So when I do diff after re-burning I see the same error in
the same location. Is there a way to force growisofs (which actually uses
mkisofs) to re-burn a file that has the same name as a file that is already
on the DVD?
My command looks like this:
$growisofs -quiet -use-the-force-luke=tty -use-the-force-luke=notray -M
/dev/dvd -r -J -T datafiletoburn.dar
Also, what is the best way to erase DVD+RW disks? I do not need to wipe all
of the data, just clear the file system tables so the disk can be re-used.
I am using:
dvd+rw-format -force /dev/dvd
But I read that this is not good for the media. It may damage the DVD+RW
after erasing it a few times? Is there a better way?
TIA
