There is a thread here: http://lists.freebsd.org/mailman/htdig/freebsd-ports/2005-March/021958.html of someone with a scsi cd-r/w that was giving the same errors. The thread goes on to post some kind of fix to a flac decoder: http://lists.freebsd.org/mailman/htdig/freebsd-ports/2005-March/021969.html ...but I don't understand how this is related or how it is to be implemented. I have found a number of postings of similar problems with k3b and scsi drives dating from after mid-2004, which is when it started happening to me, but none gives a fix. http://linux.derkeiler.com/Mailing-Lists/SuSE/2005-03/1489.html http://72.14.203.104/search?q=cache:wOJpu0m4BcwJ:k3b.plainblack.com/feedback%3Ffunc%3Dview%26wid%3D29%26forumId%3D1000%26forumOp%3DviewThread%26forumPostId%3D100898+k3b+%22mode+sense%22&hl=en&gl=us&ct=clnk&cd=1&ie=UTF-8 http://www.linuxhardware.de/deutsch/dcoulh/news_38206.html http://linuxfromscratch.org/pipermail/blfs-support/2004-June/050551.html http://72.14.203.104/search?q=cache:Dh1vQLiRy40J:bbs.cse.yzu.edu.tw/show.php%3Ftype%3Dpost%26board%3Dbsd-ports%26pageno%3D15+k3b+%22mode+sense%22&hl=en&gl=us&ct=clnk&cd=6&ie=UTF-8 http://lurker.oltrelinux.com/message/20040211.213612.0308c619.en.html Oliver > k3b on FreeBSD 6.0 incorrectly identifies my SCSI CD-R/W as read-only.
