Created attachment 49643 [details] fix post - 2.6.18 linux header reshuffle leaves MAXINT undefined Version: 1.92.0 (using KDE 4.4.5) OS: Linux The default burn format for BDR is SRM+POW, which reserves 256MB of spare clusters for defect management and pseudo-overwrite capacity. The green scroll bar shows *unformatted* capacity of 23.3GB and allows user to add that much data to the project, when in fact only 23.3GB - 0.256GB = 23.05GB of data can actually be burned. SCSI READ_CAPACITY on a SRM+POW formatted BDR returns 24756879360, which is 23.057GB. Burning the disk results in mkisofs (really genisoimage) crash 99.1% into the burn. The names of the last several files totaling 256MB will appear on the disk with their correct sizes, but their content will be missing. Reproducible: Didn't try Steps to Reproduce: Insert unformatted BDR into the drive. Select Data Project. Add file(s) to the project total larger than 23.057GB (but less than 23.3GB) Select Burn from Project menu. (Use all default settings.) Click Burn Actual Results: Progress windows shows "mkisofs crashed" 99.1% into burn. Last [up to] 256MB of files are missing or corrupt. Expected Results: All data burned correctly. OS: Linux (i686) release 2.6.32-23-generic Compiler: cc K3b version is 1.92.0 RC3-2 with 3 unreleased patches to growisofs component of dvd+rw-tools 7.1 to fix BDR burn problems. Without the patches,the BDR burn will fail in growisofs sooner, with a different error. However, the UI problem can be understood and reproduced without atually needing to burn. The problem would not have been able to be noticed and reported until I was able to get a disk to burn to the end. Developers attempting to reproduce this problem exactly (see the mkisofs crash) will need at least the three patches to growisofs I've attached.

Created attachment 49645 [details] avoid growisofs error due to invalid attempt to close session for SRM+POW mode third of three patches to dvd+rw-toos 7.1 to reproduce bug in k3b
I'm confused, this patches don't apply to K3b, do they?
