[Bug 149076] Re: I can't write a cd

Tue Jul 17 02:30:54 UTC 2012

Uh...  This seems to be interrelated to how Ubuntu chose to automount
the CD/DVD device.  Problem occurs in more than just k3b/wodim.
AcetoneISO doesn't work right.  Other burning programs don't seem to
work right.  PSXE can't see legitimate PSX discs with this problem.
Didn't occur with initial rollout of 12.04- but seems to have been
triggered later on somewhere with one of the updates.  If you explicitly
unmount all mount instances of /dev/sr0 (mine had TWO differing,
problematic mounts which explicitly referred to uid/gid) and things work
properly for all instances- so long as you don't work with the
"automatic" mount of the disc.

Basically, if it's not just a file tool or using the basic /media mount,
you're dead in the water with any of it unless you explicitly UNMOUNT it
and you need sudo access to do it with.

Title:
  I can't write a cd

Status in Python wodim Module:
  Confirmed
Status in Ubuntu:
  Invalid
Status in “cdrkit” package in Ubuntu:
  Confirmed

Bug description:
  If you see any of the symptoms of the various outputs in the comments
  the solution is as follows:

  "You are not using cdrecord but a defective fork called "wodim".

  wodim is a dead fork from a 5 year old version of cdrecord with
  bugs added that never have been in the original.

  The device or resource busy message is a result from such a bug.

  Note that you also do not use mkisofs but "genisoimage" from the
  same "fork". Note that "genisoimage" creates defective ISO filesystem
  images.

  I recommend to use the original software as there are no known bugs
  in the original software and as the original software added many new
  features during the past 6 years."

  Hi,

  After my upgrade from feisty to gutsy on my imac g3 , I tried to burn
  a cd with k3b (tried normal and clone mode) and gnomebaker, which
  didn't work. I'm using an external usb disc writer. K3B has the
  following debug info:
