The media must be formatted for packet writing mode and you must use a block size equal to the packet size ( 32k by default ).
I wish I weren't so dense. I thought the default packet size for optical media was 2k - where do you get 32k?
No, the sector size is 2k. The default packet size that cdrwtool formats the track with is 32k. I uploaded some patches to Ubuntu documenting the hidden parameter to change the packet size, and fixing a bug that prevented sizes other than 32k from working. If you download the source package from packages.ubuntu.com, you will find these patches in the debian/dpatch directory. Larger packets allow you to use more of the disk, smaller ones require that you write less at a time.
Regardless, I can't get any of the UDF formatting tools to do anything anyway 'mkudffs -r 0x0150 --media-type=worm /dev/hdc 359845' fails silently with EROFS and EBADF; 'cdrwtool -d /dev/hdd -u 359845' runs a bit, then fails with 'bad sector' IDE errors.
Is the comment about formatting the media an esoteric one or do you know something about one of the tools I'm unaware of?
Again, you can not put a udf filesystem on it. You need to use cdrwtool to only format the track, which I believe was the -m option. Once the track is formatted, you should be able to write directly to it with dd using 32kb blocks. -- To unsubscribe, e-mail: packet-writing+unsubscribe@opensuse.org For additional commands, e-mail: packet-writing+help@opensuse.org
