[Bug-xorriso] Fwd: copy from one cd to another

[Thomas Schmitt]

Hi,

for some reason, the bug-xorriso mailing list deletes the
messages which it reports to me for uthorization.
When i get to the admindb/bug-xorriso page, there is no
request pending.

So i have to forward this message now.
(I will send an answer, too.)

Subject: copy from one cd to another

Hi Thomas - I have two cd(dvd)-rw drives on my system, and wanted to
copy a cd from one to another.  That is, I have the source cd in one,
and a blank cd in the other.

I figure xorriso can surely do this, but I could not figure out how from
the documentation.  xorriso -device_links reported:
0  -dev '/dev/dvdrw'  rwrw-- :  '        ' 'iHAS124 D' 
1  -dev '/dev/dvdrw1' rwrw-- :  'ATAPI   ' 'iHAS124 D' 

Which already looked unusual to me (cdparanoia -Q reported /dev/sr0),
but ok, I'll believe anything, so I searched around and looked at the
various examples in the manual and tried:

$ xorriso -indev /dev/dvdrw1 -outdev /dev/dvdrw1

and the result, in its entirety, was:

------------------------------------------------------------------------
GNU xorriso 1.2.6 : RockRidge filesystem manipulator, libburnia project.

xorriso : NOTE : Loading ISO image tree from LBA 0
libisoburn: WARNING : No ISO 9660 image at LBA 0. Creating blank image.
Drive current: -indev '/dev/dvdrw'
Media current: CD-ROM
Media status : is written , is closed
Media summary: 1 session, 0 data blocks,     0 data,     0 free
Volume id    : 'ISOIMAGE'
Drive current: -outdev '/dev/dvdrw1'
Media current: CD-R
Media status : is blank
Media summary: 0 sessions, 0 data blocks, 0 data,  703m free
------------------------------------------------------------------------

Nothing was burned (it output the above and exited immediately).  Since
I could find no way to determine which of dvdrw and dvdrw1 was the
source and which the output, I also tried with the arguments swapped,
and a variety of other things.  Never any joy.

So I guess my request/suggestion is to put an example for this into the
manual, if it's not already there (in which case I'd be curious to know
where I missed it).

This is all with xorriso 1.2.6, compiled from the original source
release on ftp.gnu.org, running on CentOS 6.4.

BTW, Tools -> Copy CD worked fine in k3b :).

All the best,
Karl
