[Bug 1320203] Re: cannot burn dvd from iso

[Thomas Schmitt]

Hi,

> something to the effect that beyond the first 2 KB the disk is not
empty

Original message texts may help to find out what's wrong.

Currently it looks like the burn programs get no error
indication from the drive, despite it does not burn the
medium properly. 
Probably you used my libburn underneath Brasero. If the drive had
reported problems, then at least the Brasero log should contain
error messages with prefix "Libburn". (Have a look at the log.
If it is riddling, then show it here.)

If the drive is quite old and no error messages are to see, then
this might be due to physical decay.

The fact that it can burn readable CD does not confirm that it
can burn DVD. The physical properties and laser settings differ
between those media families.

> Brasero [...] goes into a hang saying "Calculating Image Checksum".

This might be an independent problem. (Not related to libburn
or drive problems.)


Let's examine:

Since you have growisofs, you probably also have the program
dvd+rw-mediainfo installed.
Put the problematic DVD into the drive (e.g. /dev/sr0), load the tray
(the program will not do this for you), and execute

  dvd+rw-mediainfo /dev/sr0

This should put out some texts which describe the medium status.
Show them here.

Further:


If you have the opportunity to read the DVD by a different drive,
then do. If it is really a physical problem between laser and
medium dye, then a different drive may well show different results.

If the DVD is readable in other drives, then your burner drive
is to blame. (If it is not readable, then the burner can still
be the culprit.)


Have a nice day :)

Thomas
