Marc, sorry the last post, I just want the information to be complete and true - after some experimenting it turns out that the only working option for large files is to use "mkisofs -udf -iso-level 3" and then mount disk as an UDF volume - if mounted as ISO9660 the large files will be doubled and truncated. I am waiting for confirmation on a usenet, you can also verify this solution please to be sure. Below is the updated note: == Note: In order to have working files larger than 4.38GB in your compilation, an UDF/ISO-9660 hybrid must be created by passing additional "-udf -iso-level 3" parameter to a mkisofs(8) and all related programs (ie. growisofs(1)). This is required only when creating an ISO image file, or writing files directly to a disk. Disk created this way must be mounted as an UDF filesystem with mount(8) utility - so it will be usable only on an UDF aware Operating System - otherwise it will look as if it contains corrupted files. To create an ISO file: %mkisofs -R -J -udf -iso-level 3 -o ../dvd.iso * To burn files directly to a disk: %growisofs -dvd-compat -R -J -udf -iso-level 3 -Z /dev/cd0 /path/to/data/* When you have an ISO image containing large files already inside, no additional options are required for growisofs(1) to burn that image on a disk. Also, be sure that you have cdrtools version >2.01, as the older ones does not contain large files support. This propagates issues in other GUI-based applications. Currently only the sysutils/cdrtools-devel port contains alpha version fresh enough to support large files, so if you experience troubles please move to the development package. == Best regards, Tomek Cedro -- CeDeROM, http://www.tomek.cedro.info
