Yes the subject of ide-scsi is a bit confusing to a newbie. Your CD-ROM is of
course IDE, but the Linux CD burning backend 'cdrecord' only works with SCSI
devices. So in order to be able to burn CDs with an IDE CD-RW the kernel
supports a 'scsi emulation' mode called ide-scsi.
Now you will say "this is a CD-ROM not a CD-RW".
If your CD-RW and CD-ROM are both ide-scsi then it is possible to do CD to CD
copying without having to copy the data to buffer first.
So that is why Mandrake has configured your CD-ROM as ide-scsi.
If you look at /etc/lilo.conf you will see the definition for your boot sector
and you will see in the 'append' line hdc=ide-scsi
Rather than mess about with your lilo.conf file I was suggesting you connect
your hard drive to the IDE secondary slave interface instead. That way it
will be /dev/hdd and you should find that diskdrake will detect the drive and
allow you to configure it.
BTW: The new Linux 2.6 kernel dispenses with the concept of ide-scsi so we may
not see this sort of question for much longer.
