Hi,

   I've installed a CD-RW on Mandrake 8.0 using ide-scsi, as described in
the Howto at http://susefaq.sourceforge.net/ide-cdrw.html Xcdroast finds
it fine, and I can read and write audio or data cds. BUT, I can't mount
it as a normal drive.

   The Howto says there should be a msg saying "detected CDROM at..." and
what it attached it to (sa0, etc). There's no such msg in
/var/log/messages or dmesg. Does this mean the kernel doesn't support
SCSI CDROMS? How do I find out? Do I have to recompile to enable
SCSI-CDROM support?

Lloyd

The kernel does, how do you use it to burn cds ? It should be something
like /dev/scd0 or /dev/scd1.

Try dmesg | grep CD

Sounds like an fstab issue. Post you /etc/fstab please.

cat /proc/modules

Is ide-scsi there? If not, that could be part of the problem. On my
system, the CD drive becomes avaiable at (block-special device) /dev/sr0.
The character-special device is /dev/sg0.

   Thanks for the reply.

   ide-scsi is there according to lsmod. I tried /dev/sr0 - it said no
such device.

   One thing I noticed on another Howto (that may have been pretty old):
it said you couldn't have IDE-CDROM and SCSI-CDROM both enabled (the
kernel just chooses the first one...). I have an IDE CDROM as well -
could that be a problem? Should I make it a pseudo-SCSI drive as well
(then xcdroast would see it, I assume)? Advantages/disadvantages of ide
vs ide-scsi?

Lloyd

Well, usually if you have a hdX=ide-scsi as parameter passed to your
kernel, all of them becomes SCSI.

Yes, you have to.

Quote:> Advantages/disadvantages of ide vs ide-scsi?

Afaik none.

Davide

  Solved it (although I still don't see why it doesn't appear in
messages...)

   This first drive is scd0, second is scd1, etc. (at least on my
system!)

   No, making the first one ide-scsi does NOT make them all that way.
I used: append="hdc=ide-scsi hdd=ide-scsi" in /etc/lilo.conf and that
worked.
