I have a similar problem with a Liteon DVD reader that works and a
Pioneer DVD writer that does not, after a fresh install of Hardy. Both
were working in Gutsy.
hdparm -i /dev/scd0
gives
======
/dev/scd0:
Model=LITEON DVD-ROM LTD-165H , FwRev=CH0J , SerialNo=

and
hdparm -i /dev/scd1
gives

Kernel is 2.6.24-19-generic and the workaround line in
/boot/grub/menu/lst is
# defoptions=quiet splash all_generic_ide=1
But that does not render the Pioneer DVD writer functional. Indeed, even
an audio CD cannot be detected on the Pioneer DVD writer, although it is
detected and playable on the Liteon.
Interestingly, on booting, I do not see a menu of choices any more even
though I also have the 2.6.24-16 kernel.
So, is there something even more fundamentally wrong?
Any pointers most appreciated.
I am happy to post more diagnostic information if told what command to
execute.
Many thanks.
