Blanking DVD

Reploid · 2008-09-21 18:54:30

Neither GnomeBaker nor K3b will let me blank my DVD+RW.

I have DVD+RW-tools installed, and have added myself to the "storage" group. I am attempting to find out how I can copy DVDs and or rip them, but when I started with K3b, I received an error message when I inserted the DVD. Attempts to blank/format them with K3b and GnomeBaker didn't work, either. I just get the following messages:

* BD/DVD±RW/-RAM format utility by <appro@fy.chalmers.se>, version 7.1.
* 4.7GB DVD+RW media detected.
umount: /media/Ubuntu 8.04 i386 is not in the fstab (and you are not root)
:-( unable to proceed with format: Device or resource busy

K3b

No need to fromat DVD+RW more than once, it may simply be overwritten

I have burnt the DVD with Ubuntu. Does that matter?

It appears that your dvd+-rw disk is being mounted by sometime of automounting daemon.

As root unmount the dvd and then try to blank it.

This doesn't make sense:

sudo umount /media/'Ubuntu 8.04 i386'
umount: /media/Ubuntu 8.04 i386: device is busy.

The output I get when starting gnomebaker using the shell:

[reploid@archcomputer media]$ sudo gnomebaker
** (gnomebaker:21473): WARNING **: devices_eject_disk - ioctl failed

Gnomebaker now gives me this error output:

umount: /media/Ubuntu 8.04 i386 is not in the fstab (and you are not root)
:-( unable to proceed with format: Device or resource busy

Which file or folder do I have to unmount really? Do I type umount /media/name_of_dvd_that_shows_up or do I type /media/another_foldername?

How do I find out which program is using the disk??

You're trying to unmount the mount folder.. you need to unmount the actual optical device. Try:

# umount /dev/sr0

One Q: how did you know that it was called sr0? The name sr0 shows up nowhere in my folder system...

It usually refers to the first optical device.
Along with /dev/scd0 and a million of others.
Why there are so many symlinks pointing to the same block device beats me.

sd, sr, and sg are just some basic naming conventions to get used to:

sdX=scsi disk
srY=scsi cdrom
sgZ=scsi generic

Say you mount your 2nd hard drive's 1st partition to /mnt/windows. You don't unmount /mnt/windows, you unmount /dev/sdb1 from /mnt/windows.

Just FYI, you can in fact unmount the folder if you have the corresponding line in your /etc/fstab.

Good to know.. thanks. I leave my opticals out of fstab, but I just tried it and it seems like HAL allows me to do it too. I've just always used #umount /dev out of habit I guess.

You're welcome. I wonder if you don't even need the line in fstab. By the way, I've gotten into the habit of ejecting rather than unmounting. Is eject unncessary for optical and flash media? If so, that'll spare me from having to type sudo before the command...
