I also see this problem on two computers (A Thinkpad X200 with external
LG USB drive, and a desktop system with an LG recorder). When copying
data from DVDs, I sometimes get "input/output errors" with cp, and
copying with nautilus fails, too, for files that seem to be beyond the
first 1GiB of the disc. in dmes, I see lots of these:
[12122.860542] sr0: rw=0, want=2097556, limit=2097151
[12122.860543] attempt to access beyond end of device
[12122.860551] sr0: rw=0, want=2097560, limit=2097151
[12122.862244] attempt to access beyond end of device
[12122.862247] sr0: rw=0, want=2097152, limit=2097151
[12122.862409] attempt to access beyond end of device
[12122.862412] sr0: rw=0, want=2097152, limit=2097151
I am running current karmic amd64 on both systems with linux 2.6.31-11.
On the laptop, unplugging the DVD drive helps sometimes. On the desktop,
I have to reboot the system. After some attempts, I can read the DVD+R
to the end, so it is no media fault.
