I have the same issue, but with one cdrom. I had originally upgraded from Edgy to Feisty via Update-Manager, but I later decided to install Feisty from scratch with the Herd 4 CD. Ever since the scratch install, I've had a double CD entry, and it gives me the same error, "special device /dev/hdb does not exist"
I'll attach my /etc/fstab and "lshal -t" as well. ** Attachment added: "output of both" http://librarian.launchpad.net/6513700/output.tar.gz -- [feisty] cdrom double entries https://launchpad.net/bugs/77990 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
