rescue an "empty" dvd

I burned a DVD-DL on my old laptop several years ago to backup my files before getting rid of it. Now I want to access these files, but the disc shows as empty in Thunar when I insert it and ddrescue run as $(ddrescue /dev/sr0 ~/output.iso) creates a 0 byte file. I can tell by looking at the back of the disc that almost the whole disc was burned (there's a ring around the outside edge that reflects differently). I think I burned it with genisoimage + cdrecord, but it was a long time ago. What program can I use to read it, or what options should I use with ddrescue?

Re: rescue an "empty" dvd

With the disk inserted, but no programs like Thunar running, what is the output of lsblk
When you insert the drive, are there any "interesting" items added to the journal?

Re: rescue an "empty" dvd

Is it possible that you didn't finalise the burn?

If so then the following should fix it...

cdrecord -fix -dev=/dev/xxx
