So i will probably need that for the IDE DVD-ROM drive that is built in too. Juergen Lock wrote: > thanks for trying to help improving libburn! :) Well, i am its active developer since a while. Any problems with it are probably my fault. Nevertheless, its FreeBSD SCSI transport is not originally by me. So i lack specific knowledge. (There are two alternative transport adapters: sg-freebsd originally by Alexander Nedotsukov, sg-libcdio for upcomming libcdio-0.83 .) > http://www.freebsd.org/cgi/query-pr.cgi?pr=138789 I will test. This was BD-R, not BD-RE, i assume ? A leadout track. Sounds very CD-ish. With DVD and BD one should rather go for READ DISC INFORMATION and READ TRACK INFORMATION. > Well if you didn't create a swap partition during install then you > don't have one. :) Not to have one seems to be an advantage now. I don't remember to have been asked. But with 4 GB of RAM i might simply have answered 'no'. > the saved state of a panic'd kernel, I assume for reporting my kernel panics i have to install a development kernel ? (Switching off-and-on a stuck USB drive is obviously not a healthy thing to do.) Well, i plan to install another FreeBSD from scratch to try reproducing drive concurrency problems which i experienced first and which vanished after installing the ports of xfburn and xorriso. First drives got stuck when disturbed while burning CD. Now the offender gets blocked until the vulnerable drive state ends. Those ports triggered a cascade of other ports. So i have no idea which one might have tweaked the configuration (or whathever happened). > Btw there also is siis(4) [...] for > SiliconImage sata controllers. > [...] sas controllers If somebody has such hardware then i would be interested to hear whether it works with libburn. Anybody is invited to ask for support. Have a nice day :) Thomas
