Trouble reading DVDs written by K3b
Hi All! I am having trouble reading DVD written by K3b in the same drive as I write them. I am using the default version that comes with SUSE 10 (0.12.3) with the version that came with SuSE 9.2, I did not have this problem. I can read them in a different Windows machine, but not my Linux machine. I am using DVD+R diskshave set it to no multisession, writing mode auto and on the fly creation. When I try DAO , it tells me I need a DVD+/-R. After I burn, I can mount the drive with no problems, but a simple ls shows: /media/dvdram/: No medium found There have been cases where I can read the root directory and see what sub-directories exist, but trying to list the contents I get an I/O error. Any help is greatly appreaciated. Regards, Jim Mohr -- --------------------------------------- "Be more concerned with your character than with your reputation.

James, I have the same problem, although not just DVDs written with k3b (I have since upgraded to the packman version), but DVDs and CDs in general.
The problem is a bit deeper. For some reason the devices for the DVD and CD drives disappear. For example, I have a DVD-RW on /dev/hda and a CD-RW on /dev/hdc (hard drive is SATA hence on sda). On a cold boot, both drives work, but after say, a day, I can no longer read discs anymore, and if I check in /dev, the hda and hdc entries are gone. Usually, doing rmmod ide_cd and rmmod cdrom, and then modprobe ide_cd and modprobe cdrom sorts it out, but not always. This is only in SUSE 10, and seems limited either to certain hardware. or to the 32bit edition. I haven't had this issue with SUSE 10.0 64-bit on my notebook, but both my home PC and work PC (both AthonXP with VIA based boards and the exact same LG DVD-RW) give this problem. Then again, on my old notebook (Pentium-3) I didn't have this problem, but that was SUSE 10.0-rc (the openSUSE version). Hope this helps Hans

Hope this helps Hans I had similar problems when writing CDs, on a boot the drive was there and would function, later the drive would disappear. I finally decided to replace

And along these lines _always_ check the firmware version of the CD/DVD device itself. Check at http://www.CDFreaks.com for your brand/model and make sure you have the latest firmware. They have links to the manufacturer's firmware updates as well as third party firmwares for some devices. They've helped me fix lots of different CD/DVD devices that had lots of different CD/DVD reading/writing problems. Stan

Thanks for the reply. Unfortunately, that did not help. I installed the packman version, but I am still getting: /media/dvdram: No medium found However, I did try the trick of removing and them re-adding the modules. That worked. <rant> It would be nice if k3b decided that there were problems with the encoding of files names **before** it started writing. I cannot even begin count how man times it barfed because a file a character in its name that k3b did not like, but already started writing the DVD or CD. After which I could only throw the media away. </rant> Regards, Jim Mohr -- --------------------------------------- "Be more concerned with your character than with your reputation.

Could you show us the output of a 'mount' command (no arguments) after mounting the drive at /media/dvdram ? I suspect the drive is mounted somewhere else.
I've had problems with nonportable DVDs, but ones written by cdrecord rather than by k3b. By looking at the k3b log I found some undocumented cdrecord parameters that k3b knows about. I used them with cdrecord and the problems went away. They had names something like "use-the-force-luke", but I can't retrieve the specific names at the moment. Paul
