DVD drive not getting mounted....cant burn DVDs


my installation is fedora 8

whenever i try to write a DVD i get the following error in K3B

unable to allocate software buffer
This error is caused by the lowmemory locked resource limit
it can be solved by issuing the command 'ulimit -l unlimited'
....or by lowering the used software buffer size in the K3B settings

then after executing the above command the error changes to

:-( attempt to re-run with -dvd-compact -dvd-compact to engage DAO or apply full blanking procedure
Write error

the debug report shows the following

Can you check the drive in a different computer to see if there is a problem with hardware ?

I can think of two possible causes of your problem. Are you writing to a DVD-RW? If so has the DVD-RW been formatted?

Are you attempting to write at a faster speed than the DVD media can write at?

Do you have a ulimit restriction on memory size? Also check where k3b creates the dvd image to burn. It might be in /home/<username>/.tmp/ or /tmp. Is there enough free space available?

You will need to post what these new problems are. We aren't psychic. What were the limits, and what is the amount of free space in the temporary directory? Also look at the end of your /var/log/messages log file. If you run against any other policy limits, they may be logged there.

Previously the size of temp folder was 1.6 gb but after changing to another drive it is now more than 5 gb.... and in /var/log/messages im not able to open any of the message log files....Also today i tried burning simple data dvd and it burned but the problem continues with DVD-RW...
Im a noob at linux at present ..so instead of being rude please be specific on what information you need(that may include giving the commands required to retrieve the info you need)

THANKS A LOT!!!

You need to be root to read /var/log/messages. For example: "tail -f /var/log/messages" will show the end of the log and follow new log messages. It is useful to run this in a terminal before running something you want information about.

Do you still get the -dvd-compat message after the changes you made? That option is for the "growisofs" program.
If you select "settings -> Configure K3B...", and click on the "programs" icon on the left, you will have a list of programs in the right hand pane. Click on the "User Parameters" tab. Select "growisofs" and click in the Parameters field. There yo u can enter "-dvd-compat".

The IO errors you are having could be from a bad disc, or it may not be properly formatted. Try reformatting it.
The IO errors might instead be due to a bad dvd device as well.

I did the changes in the configure K3B option and now my DVD device is able to burn any media (DVD+RW,CD+RW,DVD,CD).......I had been trying to ask solution to this problem from last one month .....Though this was my second time when i came back to this forum for getting this solved and have been to other forums for this too. I have got the solution to this problem on this forum only . I am really thankful to you jschiwal.....

Can you tell me what was logically wrong behind all this ?


THANKS A LOT!!!!
GOD BLESS
