What are you mounting? Once ide-scsi is in the kernel, your drive is no
longer /dev/hdc, its /dev/scd0

You shouldn't need to mount anything to burn cd's

Mounting is only for filesystems. A blank CD has no filesystem.

lsmod

Is it there?

Run modconf as root.

Choose kernel/drivers/scsi

select ide-scsi and sg

Yeh. Debain is more manual than Mandrake. Use modconf rather than mess
with modules.conf. 

Read the header of modules.conf. What does it say... "Do not edit this
file by hand".



To do a quick summary, ide-scsi is the scsi emulator for ide drives. But
if an ide drive has been recognised by the kernel, then the ide-scsi
module cant take control. The lilo/grub conf line tells the kernel to
leave that drive alone. Thus ide-scsi can take control of it when the
module is loaded. So modconf, insert the right modules, add the line to
your grub, reboot, lsmod (to make sure the modules are in the kernel)
and then 'cdrecord -scanbus' and see if your drive is being
scsi-emulated.

Then you'll need to change any symlinks, /etc/fstab entries etc. from
/dev/hdc to /dev/scd0

For example, /dev/cdrom might point to /dev/hdc. You'll need to point it
to /dev/scd0 instead.

Good luck!
