input/output issue/bug in growisofs
Dear friends,
I am becoming desparate with my DVD burner and I really would appreciate your help with this issue.
I am trying to copy DVDs with the following commands:
First I make an image of the source DVD with:
dvdbackup -i /media/hdc/ -M -o /home/andrei/DVDBackups/ -n NameOfTheBackupedDVD
Then I burn the image to a DVD+RW with:
growisofs -Z /dev/scd1 -dvd-video /home/andrei/DVDBackups/NameOfTheBackupedDVD/ -overburn
I have had growisofs incorrectly find the size of the blank DVD+RW I put in my burner (it found 2GB+ instead of the
4.7 which they have in reality). A typical error message looks like this:
:-( /dev/scd1: 2295104 blocks are free, 3589847 to be written!
So I use the -overburn option to force the burner to ignore this mistake.
I have gotten the same input/output error several times. Here are two examples:
63.93% done, estimate finish Fri Dec 29 21:19:15 2006
:-? the LUN appears to be stuck writing LBA=230540h, keep retrying in 23ms
:-[ WRITE@LBA=230540h failed with SK=5h/ASC=63h/ACQ=00h]: Input/output error
:-( write failed: Input/output error
/dev/scd1: flushing cache
/dev/scd1: writing lead-out
63.79% done, estimate finish Sat Dec 30 10:55:15 2006
63.93% done, estimate finish Sat Dec 30 10:55:15 2006
:-[ WRITE@LBA=230540h failed with SK=5h/ASC=63h/ACQ=00h]: Input/output error
:-( write failed: Input/output error
/dev/scd1: flushing cache
/dev/scd1: writing lead-out
It also happened around 58% done. I tried using three different hard drive as the input/source for the DVD image but the mistake happens again and again. Sometimes, with other DVDs it does not happen, but recently it happens a lot.
Is there a way to force growisofs to skip any writing errors? If there are errors in the source image of the DVD - I was told that some commercial DVDs have intentional errors - can I skip them?
Here is some info about my DVD burner:

I am using growisofs 7.0 under Kanotix, which is a Debian (Sid) GNU/Linux based distro.
Many thanks in advance for any pointers on how I can get growisofs to work with my hardware!
Kind regards & happy new year 2007!
