I had a similar mount problem related to a usb hard drive. Following line in /etc/fstab was the reason for this error:
/dev/sdb1 /media/cdrom0 udf,iso9660 user,noauto,exec,utf8 0 0 ubuntu declared sdb1 as a cdrom drive, which is obviously wrong. I suggest everybody with this problem to investigate the fstab file. -- Unable to mount Data DVD created under Windows XP or Vista that are in UDF format https://bugs.launchpad.net/bugs/106910 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
