[Bug 1896804] Re: CD/DVD drive detected as read only, command line and GUI programs

[Thomas Schmitt]

Hi,

> Sense Key 6 "Drive event", ASC 28 ASCQ 81.

This SCSI error reply is not listed in SCSI specs SPC or MMC or in the
summary of T10 committee
  https://www.t10.org/lists/asc-num.htm#ASC_28

So the drive's firmware programmers were overly creative.

If it was ASCQ 0 or 2, then libburn would tolerate it:
  6 28 00 NOT READY TO READY CHANGE, MEDIUM MAY HAVE CHANGED
  6 28 02 FORMAT-LAYER MAY HAVE CHANGED
but the other ASCQs of ASC 28 were too obscure to me to be tolerable.

I now made a GNU xorriso tarball with a libburn which tolerates any Drive
event error with ASC 28 so that you can drill deeper into the drive behavior.

(I have to think whether this change is good as permanent solution. The list
 of key 6 errors looks in part fatal like
   6 29 00 POWER ON, RESET, OR BUS DEVICE RESET OCCURRED
   6 3B 0F END OF MEDIUM REACHED
 but in part retryable. My program change relies on the hope that all ASC 28
 codes are harmless.)

You will need the dependency packages of pseudo-package "build-essential"
  https://packages.ubuntu.com/xenial/build-essential
then download

  https://www.gnu.org/software/xorriso/xorriso-1.5.3.tar.gz

and copy it to a directory of your choice, e.g. to
  /home/chris/xorriso

Then build it by

  cd /home/chris/xorriso
  tar xzf xorriso-1.5.3.tar.gz
  cd xorriso-1.5.3
  ./configure --prefix=/usr && make

On a modern machine the "make" part should be done in half a minute.
Afterwards there should be an executable program
  ./xorriso/xorriso

You may use it in place by its relative address

  ./xorriso/xorriso -outdev /dev/sr0 -toc

or by its absolute address

  /home/chris/xorriso/xorriso-1.5.3/xorriso/xorriso

Your Ubuntu xorriso will stay installed and your package manager cannot
get confused by the newly made xorriso. (It is quite large because it contains
own copies of libburn, libisofs, libisoburn, and libjte.)

Have a nice day :)
