Hello,
I would like to be able to read and write DVD on linux (which is not the case today !).
I explain the problem :
I have a double boot (linux Suse 10.2 and Windows XP). I am able to see and burn DVD on my ATAPI CD-ROM TSSTcorpCD/DVDW TS-H5520 while I am on Windows but not on linux !
While booting on linux, it is very slow (compare to windows), it seem because of lot of hda: lost interrupt written (25 in the dmesg).
part of dmesg :

end of the part of dmesg

The funny (or not funny) thing is that there are no
/dev/hda
but there is a folder /proc/ide/hda and the file model give :
TSSTcorpCD/DVDW TS-H552U
and the file settings give :
---------------------------------------------------------------

-------------------------------------------------------------
How can I create a /dev/hda or fixe the problem ?
My kernel is uname -r :
2.6.18.2-34-default
fdisk -l give :

In all the forum I read, they never tell that they have no device define in /dev !
Any advice is wellcome !
