Public bug reported:
Using Dapper Drake Kubuntu, reading in a nearly-full, single-sided
DVD using a command like:
dd bs=2048 if=/dev/hda of=/dev/dvdimage.iso
results in a truncated file, with a size slightly smaller than 4GiB.
Also, mounting the DVD and trying to copy it to another directory
results in I/O errors on reading some files - possibly ones that
reside past a 4GiB boundary on the DVD.
cp -a /mnt/* .
The problem does not occur under Scientific Linux 4.3 (live CD)
when loaded into RAM (to free up the optical drive), and the DVD
reads okay under Windows XP Professional and, interestingly,
the same version of Kubuntu running on an old 233MHz Pentium
box.
Any ideas?
FWIW, this Vaio is a Centrino notebook, here's the result of lspci:
