Some variable amount of overhead required for "defect management", and also overhead for the UDF filesystem itself. That page also implies you need to round the file sizes up to next multiple of 65536 bytes when computing how much space it will take to write them (which k3b apparently does not do in its estimates). Even taking all that into account, the files I tried to write should have fit, but didn't, so somewhere between 300MB and 1GB of extra space was required by something (maybe "defect management"?). -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
