Hi, i have been searching extensively and I need help. I have the Plextor PX-708A dvd burner and every time i go to write a dvd (-) format in K3B, it comes back with :

PERFORM OPC failed with SK=5h/ASC=2Ch/ACQ=00h]: Input/output error. (0.55 seconds)

Now, i looked some more after that error and after a little homework, i determined that the error stands for:

5 2C 00 COMMAND SEQUENCE ERROR

Which i got from http://fy.chalmers.se/~appro/linux/DVD+RW/keys.txt

I am aware of this thread http://www.linuxquestions.org/questions/history/185567 but there was never a real answer and one of the solutions was to install Mandrake 10.1 because it just worked after that. I am using Gentoo and kernel-2.6.9 (with all of the Gentoo patches - including the cd burning fix). I also have all of the latest cdrodao, cdrecord...etc installed, but still get the same error as above. Anyone have this burner working? If so, did you have problems like this at first? Does anybody know how to fix this?

Thanks.
Adam.

Nobody?

I had the same problem and it was the fact that /dev/cdrom was pointing to another drive rather then pointing to the Plextor one.

You can do ls -l /dev/cdrom to see were is he pointing to.

...or it was /dev/dvd??

I don't recall but it's problably a "pointer" problem..

I have the same problem, with a plextor 712A, I try to use K3B to, but I can burn CD but not the DVD
For my side the if I do an ls -l /dev/cdrom it point to my CD burner and if I do the same thing with
ls -l /dev/DVD it point on my DVD reader

What can I do in this case ?

Thanks

I had the same problem with PX708A. I concluded it was the particular media that I was using and worked around the problem by using Nautilus to burn the cd. I guess i really just avoided facing the problem.

BTW - the reason i felt it was the media, is because I have burnt handfulls of dvds prior to this problem.

Also one thing to consider...In Windows it isnt too unusuall for similar problems to occur while burning optical disks. Many times firmware updates solve allot of problems.

You have to change the /dev/dvd link to point to your dvd burner, use "ln" do "man ln" to see how to use it, you problably should use "ln -s" for a simbolic link, but I don't recall the rest of the syntax of the comand
