I had the same problem when trying to read from DVD-ROM (so no recordable), also at the 4GB border:
[10513.644000] attempt to access beyond end of device [10513.644000] hdb: rw=0, want=16328340, limit=8388604 [10513.644000] Buffer I/O error on device hdb, logical block 4082084 (see complete log in attachment) The problem vanished after stopping the packet writing tools sudo /etc/init.d/udftools stop So I suspect it has something to do with udftools. I also noticed that when writing DVD-RAMs with packet writing this silently fails (i.e. I do not get an I/O error at the prompt, but md5sum of written file reveals that it wasn't written correctly, there are also errors in dmesg in this case. Sorry, I don't have a log currently). ** Attachment added: "dmesg.log" http://launchpadlibrarian.net/12688854/dmesg.log ** Also affects: udftools (Ubuntu) Importance: Undecided Status: New -- attempt to access beyond end of device on DVD https://bugs.launchpad.net/bugs/42023 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
