I have the same problem! Have you tired "-udf" switch "-iso-level 3" or both of them? The problem is for "-iso-level 3" switch only, now I will try to use both and share the results.

The original file is 4686887250 bytes long and has 5dea4dc0d18def1978235bb4c4201569 md5 sum. The file created only with "-iso-level 3" switch is doubled and is 4294965248 bytes long and has 468f66d3d54eb06e7797106ce53a762b md5 sum. The file created both with "-udf -iso-level 3" switches is, just as above, also doubled and is 4294965248 bytes long and has 468f66d3d54eb06e7797106ce53a762b md5 sum. All this was done with latest alpha version of cdrtools: %mkisofs -version mkisofs 2.01.01a72 (i386-unknown-freebsd8.0) Copyright (C) 1993-1997 Eric Youngdale (C) 1997-2009 J�rg Schilling Joerg, how about that? You mentioned that genisoimage will produce broken filesystem and hidden messages, while mkisofs also does not produce correct data, or we still miss something :-( Please advise, Tomek

Unfortunately I'm out of DVDs right now (don't use them much), or I'd do some experimenting. -- indi Google Groupers and X-posters are filtered.

BTW. cdrecord identifies my drive as "Generic mmc2 DVD-R/DVD-RW/DVD-RAM". The machine is an intel mac mini core2duo 2GHz with "superdrive" (Pioneer DVD-RW DVR-K06). Media is Verbatin DVD+R DL. (rebooting into OS X I can burn without issues on this media). Tomek, I added a loophole to my scorefile to unblock you after seeing your posts via someone else's replies (as I've done with five other posters here).

What does that mean? I do post via google... Well about the filesystems - I have checked the filesystem generated with: 1. mkisofs -iso-level 3 -it contains malformed and doubled trucated files -it does not mount as UDF (mount_udf: /dev/cd1: Invalid argument) 2. mkisofs -iso-level 3 -udf -it contains malformed files as above when mounted as ISO9660 -it does mount as UDF (mount -t udf) and then contains one file, the checksum is correct (5dea4dc0d18def1978235bb4c4201569, filesize 4686887250) 3. genisoimage -iso-level 3 -allow-limited-size -without explicte giving the "-udf" parameter it can be mounted as UDF filesystem and chekcsum of the large file seems to be correct (5dea4dc0d18def1978235bb4c4201569, filesize 4686887250) It looks that the only working combination of the new mkisofs is the "- udf -iso-level 3" and then disk must be mounted as UDF, otherwise large files will be doubled and truncated. Can anyone confirm that? Best regards, Tomek ps/2: Indi - you can use DVD+RW for experiments - this will save your resources and the environment :-) |
