Description of problem: i am running k3b to create data files on a blu-ray writer. There is only one file to be written, a slightly less than 25gig( decimal) tar file. My first attempt failed, as the tar file was unreadable: Sep 12 16:21:56 AsusG73sw kernel: [108597.636613] attempt to access beyond end of device Sep 12 16:21:56 AsusG73sw kernel: [108597.636617] sr0: rw=0, want=48829724, limit=48829720 Sep 12 16:21:56 AsusG73sw kernel: [108597.636618] Buffer I/O error on device sr0, logical block 12207430 Sep 12 16:21:56 AsusG73sw kernel: [108597.636622] attempt to access beyond end of device Sep 12 16:21:56 AsusG73sw kernel: [108597.636623] sr0: rw=0, want=48829728, limit=48829720 Sep 12 16:21:56 AsusG73sw kernel: [108597.636625] Buffer I/O error on device sr0, logical block 12207431 After much reading, someone suggested that the "-sort" option causes the failure. In my case the sort file is empty ( but exists ). I then created the .iso file using just the mkisofs command that k3b used, as shown in the k3b log file. I can mount the .iso file via the loop mechanism, and tar can go through the multi-volume tar backup set. Version-Release number of selected component (if applicable): [root@AsusG73sw vixia]# mkisofs -version mkisofs 3.01a05 (x86_64-unknown-linux-gnu) Copyright (C) 1993-1997 Eric Youngdale (C) 1997-2010 Joerg Schilling How reproducible: Not sure, every coaster costs $1.20 to experiment with. Steps to Reproduce: 1./usr/bin/mkisofs -gui -graft-points -volid Canon_Vixia_1 -volset -appid="K3B THE CD KREATOR (C) 1998-2010 SEBASTIAN TRUEG AND MICHAL MALEK" -publisher -preparer -sysid LINUX -volset-size 1 -volset-seqno 1 -sort /tmp/kde-gat/k3bst4708.tmp -rational-rock -hide-list /tmp/kde-gat/k3bLB4708.tmp -no-cache-inodes -udf -full-iso9660-filenames -iso-level 3 -path-list /tmp/kde-gat/k3bsa4708.tmp >a.iso where "k3bsa4708.tmp" contains Canon_Vixia_2.tar=/tmp/Canon_Vixia_1.tar the other files are empty. 2. 3. Actual results: .iso file can be mounted. od -c of the tar file shows that the tar header is broken/damaged. I suppose this is a result of the kernel catching some seek error, and returning a bogus buffer. Expected results: can read the tar file without error. Additional info: Its apparent that mkisofs is broken when using the "-sort" option. There is no way to tell k3b that "sort" is broken in mkisofs, and not use it.
Thanks for reporting, I've tried to reproduce this failure with genisoimage-1.1.11-8.fc15.x86_64, but it works fine.

Please, contact author of cdrtools.
Closing this bug for now, since it works fine for me. Please, feel free to re-open it if the failure occurs in the Fedora package.
