burning cd with k3b. help.

djre · 2007-12-13 01:58:05

hi! ive been using linux for 3 months and archlinux for 2 months now. but this is the first time i needed my cd burner. i need to burn a cd. however, k3b won't do its job. It says in the k3b medium combo box, "Please insert an empty CD-R(W) medium...".

This is where Im really having trouble. See, I cannot mount blank cds and dvds. my burner is a dvdrom/cdr-writer. I dont know why but if I mount a blank cd or a dvd and call mount /dev/cdrom, it display this error message:
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
In some cases useful info is found in syslog - try dmesg | tail or so

calling dmesg |tail gives this output:
Buffer I/O error on device sr0, logical block 0
end_request: I/O error, dev sr0, sectro 1201792
end_request: I/O error, dev sr0, sector 1201796
end_request: I/O error, dev sr0, sector 0
cdrom: sr0: mrw address space DMA selected
end_request: I/O error, dev sr0, sector 64
isofs_fill_super: bread failed, dev=sr0, iso_blknum=16, block=16
cdrom: sr0: mrw address space DMA selected
end_request: I/O error, dev sr0, sector 64
isofs_fill_super: bread failed, dev=sr0, iso_blknum=16, block=16

calling ls -l /dev/cdrom gives this output:
lrwxrwxrwx 1 root root 17 2007-12-13 00:48 /dev/cdrom -> /dev/cd/cdrom-sr0

Please look into my situation. Thanks very much.

It is normal to not be able to mount a blank cd, they have no file system so there is really no way it can be mounted. I'm not sure I understand what your trouble is with k3b but it looks like from your dmesg that your device is /dev/sr0. Try setting the device to that in k3b. Of course you can always burn the trusty command line way:

find which device your burner is:

cdrecord --devices

burn:

cdrecord dev=/dev/sr0 driveropts=burnfree -v /path/to/iso

add a -dao if you are burning a DVD

thanks. weird, cdrecord --devices show that my device is dev='/dev/scd0' but when i look at k3b device settings the system device name displayed is /dev/sr0. could that be the problem?

i tried adding dev/scd0 to the devices in k3b but it says could not find additional device at /dev/scd0

K3b performs very nicely with either DVD or CD discs.

There are several options found at the outset when k3b is opened.

If you desire you can select one of these for your project.

Also you can ignore those and select under TOOLS the desired recording mode.

With a dvdrom you probably will see SRO as the ID.

In K3b the selected device is presented in the display.

If you select in TOOLS a cdrom activity, the cdrom particulars will be utilized. If you select DVD, the DVD particulars will be displayed.

There is no need to mount either device type, K3b is automatic.

Perhaps these comments will aid you altho they are somewhat obvious:rolleyes:

ls -ot /dev/scd0 will show it is symlinked to /dev/sr0
