Meanwhile 12 years old is my scdbackup. It puts a given set of file trees onto one or more media. The emphasis is more on safety with moving targets than on optimum usage of the media capacity, though. If it would squeeze out the last few sectors, then it would be very prone to changes of file tree sizes. isopack got more packing algorithms than scdbackup. But it seems that you are planning only for a single medium. I understand you plan for leaving out those file groups which do not belong to the chosen packing. This leaves me with the question, how the user learns about those groups which did not make it yet and would be candidates for the next ISO image in the next medium. In scdbackup i have an algorithm similar to your ffd. Once it was default. But i dropped it in favor of a more wasteful alphabetic packing, which leads to a set of backup volumes that can be labeled like an encyclopedia. Another question i have, is how you predict the exact size of an ISO 9660 image with Rock Ridge. It is not impossible but depends on the internals of the ISO 9660 generator program. So in principle one can only trust the -print-size result with the whole tree of files which would be candidates for the image. > I haven't yet tried writing a disc packed > via isopack to see if it really does fit :-) The sizes on the web page look ok. Maybe you could add some re-usable ones: 2295104 12 cm DVD+RW 2297888 12 cm DVD-RW formatted (profile 0x13) 2298496 12 cm DVD-RW not formatted (profile 0x14) 11826176 12 cm BD-RE single layer, default format 12219392 12 cm BD-RE single layer, formatted to 0 spare blocks Further, consider to mention that BD-R may be formatted and thus may have less sectors of payload than the maximum values on your web page. Default formatted size is 11826176. Have a nice day :) Thomas -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe". Trouble?
