From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.2) Gecko/20040809 Description of problem: k3b falsely detects a SCSI CD writer as a reader device (and thus refuses to write to it, naturally). This is the same machine as in https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=130864, it has an ATAPI DVD writer and a SCSI CD writer. The ATAPI device is correctly detected as a writer by k3b (but not usable due to the cdrecord issues mentioned in bug 130864), the SCSI CD writer is detected as a reader device (although it works fine from the command line using cdrecord). Kind of annoying :) Attached is a screenshot from k3b configuration dialog showing the CD writer. Although not visible on the screenshot this shows the "Reader" device tree. Please note that k3b (correctly) shows that the device is capable of writing CD/RW, but treats it as a reader nontheless. Version-Release number of selected component (if applicable): k3b-0.11.12-2 How reproducible: Always Steps to Reproduce: 1. Start k3b with a SCSI CD writer 2. Look in the configuration dialog where the device is listed 3. Actual Results: Device is listed as a reader Expected Results: Device is listed as a writer Additional info:

Similar problem here with two ATAPI writers in both FC2 and FC3T1. A Samsung CD-R/RW SW-240B and a Plextor DVDR PX-712A. The Samsung is listed as a Reader, but shows burning capabilities for CD/RWs but not CDs. The Plextor is listed as a writer, but says no for "Writes CDs" and "Writes DVD+R(W)s", and says yes for "Writes CD/RWs", "Reads DVDs" and "Writes DVD-R(W)s" It is capable of all these writes. An older K3b I use in FC1 lists both devices as writers and writes CDs with both of these devices.
I think "Writes CDs: no" is correct for all writing devices available to normal customers :) I checked my DVD writers entries, however, and it also states "Writes DVD+R(W): no", which is incorrect.
could you please provide the ownership and permissions of the device files? e.g. # ls -l /dev/hdc or # ls -l /dev/scd0
File is mode 600, owned by the user currently logged in (as set by /etc/security/console.perms)
Just checking - does the output change if you run k3b as root?
newer kernels seem to be very restrictive about certain SCSI commands from non-root users, I think..
When running k3b as root (tested by logging into X as normal user, opening an xterm, doing "su" and then k3b) shows every SCSI drive in the system twice in the configuration dialog, but the SCSI writer is correctly listed as a writing device (albeit twice)
Same problem here. Read from http://k3b.plainblack.com/index.pl/news2 the interesting information: (yes, booting a 2.6.7-1.517 kernel fixed it) Do not use Kernel 2.6.8 A patch that was introduced into the kernel shortly before the 2.6.8 release makes K3b and also the dvd+rw-tools unusable on Linux (unless run as root but that is not recommended). The very important GET CONFIGURATION MMC command is rejected by the kernel for reasons I cannot see and writing commands like MODE SELECT also fail (K3b cannot detect CD writers without it) even when the device is opened O_RDWR. Until this issue has been solved I strongly recommend to stick to kernel version 2.6.7. Update: The kernel guys are currently fixing the problem so the next kernel release should work again. :) Update 2: The problem is NOT fixed in 2.6.8.1 Update 3: Be aware that kernel 2.6.8 also contains the memory leak which makes it impossible to write audio cds, even as root.
well, kernel 2.6.8-1.532 did not fix it. Still on 2.6.7-1.517.
