I faced a problem with dvd+rw-tools (6.0, 6.1 und 7.0) when I tried to burn a DVD-Iso-Image to a dvd using the command linegrowisofs -Z /dev/scd2=/media/CDWserver/export/Server/DVD-Images/KNOPPIX_V5.0.1DVD-2006-06-01-DE.iso But it gives an invalid argument error:---- OutputExecuting 'builtin_dd if=/media/CDWserver/export/Server/DVD-Images/KNOPPIX_V5.0.1DVD-2006-06-01-DE.iso of=/dev/scd2 obs=32k seek=0':-( write failed: Invalid argument ----------------------------
This was a problem with 6.x on Linux for files residing on NFS, but it's fixed in 7.0. Double-check that you're running 7.0 and run the command under strace [on Linux or whatever system call tracing utility for your OS] and [to save the public bandwidth] send the system call trace to me.
The following command line works well: cat KNOPPIX_V5.0.1DVD-2006-06-01-DE.iso | growisofs -Z /dev/scd2=/dev/fd/0Why is there is difference between these two commands. Why does the second work and the first not?
I'd bet on the fact that growisofs opens file with O_DIRECT, while cat doesn't. A.
