What would be an 'old' tool for packing files into an ISO image that you were improving upon? Looking for Windows GUI-based tools here, to pack offloads onto DVDs. As far as I know, there is no old tool for doing this. This one is new because I just wrote it, not because it replicates the function of some old tool (at least I couldn't find any existing tool or I probably wouldn't have written this one :-). There is a useful tool for determining what will fit on a media size, and it has been around. since the mid 1990s, called breaker. It takes as input a list of items and sizes, such as are creates by ls -s | sort -n or du -S | sort -n and you provide the size of the media, optional rounding up in size of each item, optional fixed overhead per item (tar/cpio headers), and have options to generate a file list inone-file-per-media format and optionally use a format suitable for the "graftpoints" option in cdrecord. It's still on public.tmr.com as source, I started it before CD burners were common and I was backing up a massice 600MB drive to 60MB takes. The problem hasn't changed, the numbers have just gotten bigger. :-( -- Bill Davidsen We are not out of the woods yet, but we know the direction and have taken the first step.

Re: cdrskin: how to get quick BD-RE format?
Hi, > > blank=format_defectmgt_cert_off > Ok, but this is not "automatic" as as_needed, right? Well ... the manual says one can combine it with other blank= options. Interesting challenge. So i try: $ cdrskin -vv dev=/dev/sr3 \ blank=format_defectmgt_cert_off blank=as_needed ... cdrskin: status 1 burn_disc_blank "The drive holds a blank disc" Current: BD-RE cdrskin: NOTE : blank=as_needed : no need for action detected $ Looks ok for the case of an already formatted disk. (-vv causes the "NOTE" message in case of inaction.) Be so kind and test with an unformatted BD-RE whether it is quicker than blank=as_needed alone. Note that the sequence of blank= options matters here. First _cert_off, then as_needed to override the unconditional aspect of _cert_off. > So, first I should check with > cdrskin -minfo -v > if > disk status: empty > So as to format only when "empty". In principle, yes. I'd advise --list_formats, though: $ cdrskin -v dev=/dev/sr3 --list_formats 2>/dev/null | \ fgrep 'Format status' Format status: unformatted, up to 23866.0 MiB $ In contrast to Format status: formatted, with 23098.0 MiB > Does this work for BD-R too? Besides the fact that BD-R work unformatted too, "empty" should indeed indicate a BD-R that is still formattable. You will need option blank=format_if_needed because blank=as_needed will be satisfied with seeing a blank BD-R (unlike with BD-RE which cannot be used unformatted). Option --list_formats yields: Unused BD-R: Format status: unformatted, up to 23866.0 MiB Unformatted used BD-R: Format status: written, with 9690.4 MiB BD Spare Area: 0 blocks consumed, 0 blocks available Formatted used BD-R: Format status: written, with 13682.4 MiB BD Spare Area: 0 blocks consumed, 196608 blocks available Have a nice day :) Thomas -- To UNSUBSCRIBE, email to cdwrite-requ...@other.debian.org with a subject of "unsubscribe".

Probably the difference is in the Sub-type field of the FORMAT UNIT command. dvd+rw-format uses type 2 for "-format=full" and type 3 else. The matching cdrskin blank type of cdrskin for Sub-type 2 would be blank=format_defectmgt_cert_off This formats to default size. You may chose other format sizes by a further blank= option. Like: blank=format_defectmgt_cert_off blank=format_defectmgt_payload_23610m or blank=format_defectmgt_cert_off blank=format_by_index_2 The latter refers to the idx numbers as listed by $ cdrskin -v dev=/dev/sr3 --list_formats ... BD Spare Area: 0 blocks consumed, 393216 blocks available Format idx 0 : 00h , 11826176s , 23098.0 MiB Format idx 1 : 01h , 11564032s , 22586.0 MiB Format idx 2 : 30h , 11826176s , 23098.0 MiB Format idx 3 : 30h , 11564032s , 22586.0 MiB Format idx 4 : 30h , 12088320s , 23610.0 MiB Format idx 5 : 31h , 12219392s , 23866.0 MiB format_defectmgt_payload_... can be chosen quite freely. But extreme wishes might lead to rejection of the FORMAT UNIT command by the drive. > Should I try > format=format_if_needed > instead? For BD-RW this has the same effect as "as_needed". It will make a difference with CD-RW (no action rather than blanking), with DVD-RW (formatting rather than blanking), or unused BD-R (formatting rather than no action).

cdrskin: how to get quick BD-RE format?
cdrskin-1.1.8, Linux RHEL3 LG BE06LU10/YE05 I used to check if the inserted media was an unformatted BD-RE and, if so, I'd issue dvd+rw-format /dev/cdrom to format it before calling cdrskin to write to it. Now I'm trying to do w/o dvd+rw-format, so I added format=as_needed to the cdrskin command line already used for burning, and taken out "dvd+rw-format" Now cdrskin will automatically format a blank BD-RE, but it's doing a full format (ie: more than 1 hour for a 2x BD-RE), while dvd+rw-format would do a quick (a few minutes if I remember correctly) format, just enough to get it going. Should I try format=format_if_needed instead? From reading the manual is't not clear to me when I would want to use format_if_needed or as_needed when I want cdrsin to automatically format BD-RE/BD-R is they are blank.
