Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Make sure you are using a new version of dvd+rw-tools and that the medium is formatted first if and only if it is dvd+rw. Only virgin media needs to be formatted, otherwise dvd+rw-tools will reformat it for you initially.
Also, you should use scsi emulation during boot:
I added the ide-scsi simulation, but when I put I still get errors. Growisofs output ":-( /dev/hdc: media is not recognized as recordable DVD: 0". I think it's because the drive is in read only (O-RDONLY), but I can't quite figure out what the problem is.
I'm sorry, I didn't realize you were running mandrake! You must take it out of it's automounter control. I would edit /etc/fstab and see if it is ro and contains supermount. Comment out that line and exit. Then, umount the device in question. Now burning should work. What dvd format are you trying to burn? dvd-r[w] dvd+r[w] dvd-ram, or what? That's important.
I killed automount and ro, but am still getting the error. When I try to mount the drive, I get:
mount: block device /dev/hdc is write-protected, mounting read-only
mount: No medium found
Still Read-only. When I now try to get umount the drive, I get:
umount: /dev/hdc: not mounted
Okay, it seems that the drive isn't mount at all. Regardless, I go to k3b and try to burn a cd. I get the exact same error meessage as if it were supermount and ro, and I don't think the thing is mount at all! I'm really perplexed here. Thanks for the help.
If you have scsi emulation turned on you can't mount /dev/hdc you must mount like this:
# mount -t iso9660 /dev/scd0 /mnt/cdrom
# mount -t iso9660 /dev/sg0 /mnt/cdrom
# mount -t iso9660 /dev/sda /mnt/cdrom
assuming /mnt/cdrom exists and the cd or dvd contains an iso9660 fs, if not try "-t udf" for video dvds.
Are you trying to mount an empty cd or dvd. Obviously that won't work! I still don't know what type of dvd you are trying to burn, please let me know.
Regardless of what mounting does the following commands should work if
lsmod lists the ide-scsi module in its output:
# growisofs -Z /dev/scd0=/location/and/name/of/dvd.iso
# growisofs -Z /dev/sg0=/location/and/name/of/dvd.iso
# growisofs -Z /dev/sda=/location/and/name/of/dvd.iso
Hmm... It seems that I've been relatively stupid about this the whole time. I never had ide-scsi on, depsite my think I did. So I actually have ito n now, and use /dev/scd0. I tried with supermount and ro; failure. I tried supermount and no ro; failure. I tried no supermount, and now I can't mount it at all, I get permission denied as root.
On bootup, a message comes up saying that it is mounting it as read-only, as well as that it can't read superblock.

Originally posted by Inexactitude Very strange....I was able to burn a regular cd on the dvd drive, but I get medium errors when usinga dvd. I've tried dvd-r and dvd+r, all to no avail. What can I do to fix this up?
I take it it doesn't actually start the burn?
What's the error message exactly?
Is there anything in /var/log/messages or in the output from the dmesg command?
Do you run another OS that you could check out the drive with?
I'm using growisofs 5.17, k3b 0.11, with an MSI DR8-A DVD burner on RH9. So far DVD+RW and CD-RW/CD-R have all worked. This is under RH9 with kernel 2.4.20(RH) and 2.6.3.
The only problem I've had is when the unit was too hot and dmesg reported a tracking servo failure in the middle of a burn - this was after using the drive continuously for an hour including two simulated burns. After it cooled down it was fine.
I was able to fix the problem. I tried burning the dvd from knoppix, which worked. So I then got the newest version of dvd-rw tools and compiled it from source, and then everything worked fine. I guess that the rpm package thar ships with mandrake is messed up.
The rpm that comes with Mandrake 9.2 for dvd+rw-tools was givin me hell too! I kept getting an error about the write speed being incorrect and it would refuse to burn. I spent 2 days trying to figure it out, finally I downloaded and compiled from source and I was burnin dvds within one minute!
Play back on what?
If you mean a standalone dvd video player then do:
# growisofs -dvd-compat
That command alone won't work, but if you add the -dvd-compat option to growisofs, it should work. Also, some media, dvd+rw I think needs:
# dvd+rw-format -lead-out /dev/your_device
after a burn in order to work!
