hi, i'm a relative linux newbie, and this is my first post/plea for help! i've browsing the forums, how-tos and faqs without finding a reference to a similar problem, so i hope that this isn't the millionth post about this. using a fujitsu s2020 (athlon 2100+XPM, with an ide dvd-cdrw) running demudi with its 2.4.25 kernel.

i'm trying to use k3b (which seems installed just fine, since it runs) but it can't find any "read" devices (i have only the one internal dvd/cdrw). the scsi-ide emulation seems to be working, but it looks like it finds 7 versions of my toshiba dvd-cdrw drive as scsi devices. in the k3b configuration menu, it lists all 7 under "write devices" and none under "read". i read somewhere about LUN or something, but i don't know what that is yet...

here's my fstab:

proc /proc proc defaults 0 0
/dev/hda2 / ext3 defaults,errors=remount-ro 0 1
/dev/hda5 none swap sw 0 0
/dev/scd0 /media/cdrom0 iso9660 rw,user,noauto 0 0


and (i hope all of) the pertinent lines from /var/log/messages:

thanks in advance for any help!

It's a kernel compile option, 'Probe all LUNs on each SCSI device' I believe it's a default kernel compile option on most of the major distributions. I have it turned on on my default Slackware 10 install, but don't get the multiple drive business in my logs for my CD-RW drive.

If you use lilo to boot your distribution, add the line:

append="hd(x)=ide-scsi

to your lilo.conf file. hd(x) is where your burner is. My line reads: append="hdb=ide-scsi" since my burner is on /dev/hdb Check out where your burner is on boot next time, to see where it is. There's usually some interesting message that comes up saying DVD-RW or something along with where it's attached to.
