(I tried sending this to the author of dvd+rw-tools but did not receive
any reply... I thought I'd ask here since there was a previous thread
about reading from the end of a disc. Any ideas from you guys?)
I just purchased a DVD rewriter and ran in to a problem accessing the end
of the disk.
I can create a 720MB ISO9660 image with mkisofs and mount it with "-o loop"
just fine. However, after burning it to a DVD+RW, I get an error around the
700MB (after 341360 blocks, to be exact) mark with "dd". Just trying to read
the files on the disc gives the same I/O error. I'm using the 2.6.3 Linux
kernel. Here are the steps I did on a DVD+RW disc:
dvd+rw-format /dev/dvd
growisofs -Z /dev/dvd=/tmp/cd-rZN93I.iso
cat /dvd/015-install-wall-1.avi >/dev/null
cat: /dvd/015-install-wall-1.avi: Input/output error
dd if=/dev/dvd of=/dev/null bs=2k
341360+0 records in
341360+0 records out
699105280 bytes transferred in 124.9 seconds (5597196 bytes/sec)
I thought perhaps it was a problem with the write, so I switched to XP
(running under vmware) and could read every file on the disk. Then I used
Nero to burn the same files. When I try to read this disk under Linux, I
get the same problem as above even though XP can read everything is just
fine. I'd say it's not a a physical or filesystem error.
Any ideas? Thanks!
