Can't burn CD image

X04D · 2008-01-21 04:11:01

Not sure what's happening here but my dvd rw apparently no longer works, at least, not in Arch.

sudo mount /dev/scd0

mount: block device /dev/sr0 is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/sr0,
missing codepage or other error
(could this be the IDE device where you in fact use
ide-scsi so that sr0 or sda or so is needed?)
In some cases useful info is found in syslog - try
dmesg | tail or so

cat /etc/fstab (relevant line)

/dev/scd0 /mnt/dvd udf,iso9660 user,noauto 0 0

cat /etc/mtab

/dev/sda2 / ext3 rw 0 0
none /proc proc rw 0 0
none /sys sysfs rw 0 0
none /dev ramfs rw 0 0
none /proc/bus/usb usbfs rw 0 0
none /dev/pts devpts rw 0 0
none /dev/shm tmpfs rw 0 0
/dev/sda1 /home ext3 rw 0 0

dmesg|tail

end_request: I/O error, dev sr0, sector 64
end_request: I/O error, dev sr0, sector 1248

end_request: I/O error, dev sr0, sector 64
isofs_fill_super: bread failed, dev=sr0, iso_blknum=16, block=16

Commenting out the line doesn't help, it just gives me an error about /dev/scd0 not being in /etc/fstab or /etc/mtab. Rebooting doesn't help.

Any ideas?

Change /dev/scd0 to /dev/sr0 in /etc/fstab and/or on the command line.

sudo mount /dev/sr0

Anyone?

I don't get it. I just put in a data DVD and copied a bunch of files off it. But I can't write an image to a DVD?

Were you trying to mount a blank DVD to write to it? You can only mount devices with file systems on them. If you want to burn a DVD, just insert a blank one, fire up your favorite burning software, and away you go.

Ah.

Hm...

After a reboot...

growisofs -dvd-compat -Z /dev/sr0=/home/loke/debian-40r2-i386-netinst.iso
:-( unable to open64("/dev/sr0",O_RDONLY): Permission denied

Here we go again.

Arch is awesome, so glad I tried it!

I don't know if it's related, but I see you didn't mount your dvdrw as writable.

The wiki about fstab is rather well documented, so give the options 'user' and 'rw' a try. Here at work I mount my dvdrw also as a 'auto'-fs instead of 'udf,iso9660'.

Zl.

peart · 2008-01-21 17:15:21

I just thought of 2 other possibilities:
1) Your user might need to be in the optical group.
2) If all else fails, there's always the Wiki: http://wiki.archlinux.org/index.php/DVD_writing

It works for me... which means that most likely something is misconfigured on your system.

$ growisofs -dvd-compat -Z /dev/scd0=/home/filip/crux-2.4.iso
Executing 'builtin_dd if=/home/filip/crux-2.4.iso of=/dev/scd0 obs=32k seek=0'

I use hal to do the mounting so my fstab looks like this:

#/dev/dvd /mnt/dvd    udf    ro,user,noauto,unhide 0 0

/dev/sda2 swap swap defaults 0 0
/dev/sda3 / reiserfs    noatime,notail 0 1
/dev/sda4 /home reiserfs    noatime,notail 0 1

Here are my user's groups:

$ groups
tty lp wheel log network video audio optical floppy storage camera power users filip tex

Here are my daemons from /etc/rc.d:

DAEMONS=(syslog-ng preload autowifi acpid laptop-mode alsa crond fam hal mpd sshd)

/etc/mtab with blank dvd-r in the drive:

/dev/sda3 / reiserfs rw,noatime,notail,commit=0 0 0
(...)
/dev/sda1 /boot ext2 rw 0 0
/dev/sda4 /home reiserfs rw,noatime,notail,commit=0 0 0

/etc/mtab with a written dvd mounted by hal:
