DVD to ISO image

logosys · 10-09-2005, 08:58 PM

Howdy,

I'm trying to save ISO images of my DVD's onto one of my hard drives, and, unfortunately, I can't get the thing to work properly. I insert the DVD into the proper drive and run:

Code:

# dd if=/dev/hdc of=/backup/media/dvd/Indiana_Jones-Temple_of_Doom.iso
dd: reading `/dev/hdc': Input/output error
2000+0 records in
2000+0 records out

And the iso it creates isn't right. Now, doing that same thing worked for all my CD's, so is there something different I have to do with DVD's? Could there be a plugin or some such that I'm missing? Thanks for your help, it's much appreciated.

Have you mounted /dev/hdc? Try using the mount point as the if= parameter.

Nope, no joy....
Any other ideas?

"Input/output error" - that's what I get when a CD or floppy is faulty.
Have you tried with more than one disc?
If you mount it in a text-console and access it, do you get any error messages?

... and just to make sure: you do have enough free space where the disc is to be copied to?

I think the encryption on DVD causes CRC problems. I use DVDshrink for Windows under wine. Its a bit of a pain to set up but it works. There are several threads hear on LQ on it. If you don't wanna shrink it I think it will let you do that too.

Otherwise there is also vobcopy (Linux) that beats this problem. Vobcopy lets you do this with:

Code:

vobcopy /mnt/cdrom2 -l -n 1 -O . -t \"~/DVD_tmp\"
mkisofs -dvd-video -udf DVD_tmp/ > ~/DVD_iso/tmp.iso
