Found this and killed it

  hald-addon-storage: polling /dev/sr0 (every 2 sec)

I waited about 20 secs every time.

I have an age-old CD-RW I could play with (if it still
works) and a single DVD-RW which is just as old.

At the moment, I am burning an image onto the
DVD-RW at the blazing speed of 400-500 kB/s aka
0.30x speed.
See dvd-asus-ion_dvd-iso_defaults for that. Note that
I cancelled this burn to try the other media.
A burn run with a DVD-R is hanging at the moment so
I will go to bed now and try the CD-RW tomorrow.

Yes, unfortunately.

If possible, I would like to avoid this. On the other
hand if I can be reasonably sure that it is in fact
a hardware defect, I will send it back on Monday.

I tried some cheap Maxell ones (cheap enough to waste
a dozen or two with various methods, now) and Verbatim
Azo.

It is probably important to emphasize that the CD blanks
are _not_ usable after a test run, any more. I.e.,
_something_ happens.

It wants to burn with 40x, but I learned the hard way to
always choose the slowest speed offered by any drive.


Also of note is that while the drive was on the 'Raid'
SATA port, I could not boot from CD. When I switched
over to the 'normal' SATA ports (with a new cable) I
could boot from CD.

All burn logs in this email are from this new setup.


Out interest, I tried the schily cdrecord as well.
See [1] and [2] for reference.


Thanks a lot!
