[K3b-user] DVD verify with growisofs works, CD verify with wodin fails, but both written correctly

[Arthur M. <art...@in...>]

Hi, I just posted this to the Debian bug-tracker (which hasn't responded 
with a bug number yet).

If anyone can offer some suggestions to try to see why CD verify fails 
even when the CD is written correctly, I'd be happy to burn a few CD-RW 
disks and observe the results.


Package: k3b
Version: 1.0.5-3+b1
Severity: normal


Hi, I recently acquired an LG DVD writer identified in dmesg as:

hdb: HL-DT-STDVD-RAM GH22NP20, ATAPI CD/DVD-ROM drive
ide-cd: hdb: ATAPI 48X DVD-ROM DVD-R/RAM CD-R/RW drive, 2048kB Cache

When I burned a DVD (which used growisofs), verify succeeded, but
when I burned a CD (which used wodin), verify failed.

I then found a shell script to re-check the md5sum of the burned media
against the md5sum of the .iso file:

#!/bin/bash
  #shell script to verify a burned iso

  ISOFILE=$1
  echo "Isofile: " $ISOFILE
  DVDDRIVE=/dev/hdb
  BYTES=2048

  #Get the number of extends
  NROFEXTENDS=$(($(ls -l $ISOFILE | awk '{ print $5 }') / $BYTES ))
  echo "Nr of extends: " $NROFEXTENDS

  #Get MD5 sum of DVD
  dd if=$DVDDRIVE bs=$BYTES count=$NROFEXTENDS | md5sum

  #Get MD5 sum of iso file
  md5sum $ISOFILE

and this showed that the CD burned with k3b, which called wodin, had in
fact been written correctly.

If someone needs me to do further tests I will purchase some cd-rw disks
and be happy to try again.

Arthur.
