cannot burn dvd from iso

[pramathesh ambasta]

I was not able to burn a Ubuntu Gnome 14.04 iso image to DVD. I used K3B, Brasero and growisofs from the command line in that order.

Funny thing is that there is no error message or any other message. K3B and growisofs both show successful completion. When I insert the disk into the tray and close the tray, it shows up as a blank DVD+R once again!

However trying to write to this blank DVD again results in an error (something to the effect that beyond the first 2 KB the disk is not empty).

Brasero on the other hand shows the disk as being written without error but goes into a hang saying "Calculating Image Checksum".

Forgot to add that I checked my DVD drive by trying to write a CD with some files in my home directory from K3B. They were written properly

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 :)
