Good afternoon

I m sorry again.
dd does not work.

I put in a "good" DVD.
dd if=/dev/dvd of=/path/to/dvdcopy.iso
is working and I can convert the ISO
But I put in the damaged DVD
dd cannot start.

again, you forgot to explain what (sort of a) DVD that is, and what the actual error is.

How about:

How about: Your DVD is broken and will not be readable. Put it into the proper recycling bin/bag.

dvdread
ddrescue
debiandvdbackup
acidrip
isobuster and wine.

Are you aware that some of those tools have very specific purposes and use cases? If so, why do you believe anybody can comment without information about *you* use case?

Second:How can I use dd and others with an external dvddrive?

dd if=<put-proper-device-node-here> [some reasonable options]

Cheers,

Arno

Regards
Sophie
