Hello guys,

I've a double-side video cdrom. Inside it there is a film: Conjuring.

I've tryed to clone the cdrom using:

dd if=/dev/cd0 of=conjuring.iso bs=2048

but I receive an error message:

dd: /dev/cd0: Input/output error

and the cloning is stopped after few bytes copied.

Can you tell me please why ?
How can I do ?

Thanks very much in advance.
 
Hey,

unfortunately you cannot simply DD protected DVD media.
There is probably SecuROM or similar security protection applied.

You can try with DVDBackup package which dumps DVD content into disk folder or something similar but I believe libdvdsecure would not support secuROM.

Regards,
Krzysztof
