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 :-[ [EMAIL PROTECTED] 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 :-[ [EMAIL PROTECTED] 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: dvd+rw-mediainfo /dev/scd1 INQUIRY: [TSSTcorp][CD/DVDW SH-S182D][SB00] GET [CURRENT] CONFIGURATION: Mounted Media: 1Ah, DVD+RW Current Write Speed: 4.0x1385=5540KB/s Write Speed #0: 4.0x1385=5540KB/s Write Speed #1: 2.0x1385=2770KB/s GET [CURRENT] PERFORMANCE: Write Performance: 4.0x1385=5540KB/[EMAIL PROTECTED] -> 2295104] Speed Descriptor#0: 00/2295103 [EMAIL PROTECTED]/s [EMAIL PROTECTED] =5540KB/s Speed Descriptor#1: 00/2295103 [EMAIL PROTECTED]/s [EMAIL PROTECTED]/s Speed Descriptor#2: 00/2295103 [EMAIL PROTECTED]/s [EMAIL PROTECTED]/s READ DVD STRUCTURE[#0h]: Media Book Type: 00h, DVD-ROM book [revision 0] Media ID: MKM/A02 Legacy lead-out at: 2295104*2KB=4700372992 READ DISC INFORMATION: Disc status: complete Number of Sessions: 1 State of Last Session: complete Number of Tracks: 1 BG Format Status: complete READ FORMAT CAPACITIES: formatted: 2295104*2048=4700372992 26h(0): 2295104*2048=4700372992 READ TRACK INFORMATION[#1]: Track State: complete Track Start Address: 0*2KB Free Blocks: 0*2KB Track Size: 2295104*2KB FABRICATED TOC: Track#1 : [EMAIL PROTECTED] Track#AA : [EMAIL PROTECTED] Multi-session Info: [EMAIL PROTECTED] READ CAPACITY: 2295104*2048=4700372992 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! Andrei
