Duplicating a DVD-ROM

cdhgee · 06-02-2006, 06:22 AM

I was trying to copy a DVD that I had burned last night, using the following command

Code:

dd if=/dev/dvd1 of=/dev/dvd

but it kept giving me I/O errors. Does anyone know if this method should work, or do I have to do it by the convoluted route:

Code:

dd if=/dev/dvd1 of=dvd.iso
growisofs -dvd-compat -Z /dev/dvd=dvd.iso

linux can not directly write (except for DirectCD or InCD formatted disks) to a CD/DVD. You need to do burn via the convoluted route.

Thanks michaelk. I had a thought - do you think something like the following would work, as a way to remove the middle step of writing out to an iso and then burning that to disc?

Code:

growisofs -dvd-compat -Z /dev/dvd=`dd if=/dev/dvd1`

Thanks in advance. Regards,
