Works without problems here - are you sure you used the right device numbers
and names?

I have a very similar setup - in my case 24x ATAPI CD-ROM and 4x2x2 ATAPI CD-RW
- and admit that I was puzzled at first with how to get them both set up.

The working hardware setup here that allows me to write to the CD-RW using
cdrecord is as follows:

  hda = Hard drive
  hdb = CD-ROM
  hdc = Zip
  hdd = CD-RW

To get them all working as required, I have to specify in /etc/lilo.conf that
hda and hdb use the standard IDE driver, hdc uses the IDE-Floppy driver and hdd
uses the IDE-SCSI driver. I also need to have all three drivers hard compiled
into the kernel, as otherwise the specifications are ignored.

With this setup, the drives are actually referred to as follows:

       Hardware    Device       Software
       ~~~~~~~~    ~~~~~~~~~    ~~~~~~~~
         hda       Hard disk      hda
         hdb       CD-ROM         hdb
         hdc       Zip-250        hdc
         hdd       CD-RW          sr0         <=== Note this

Note the changed reference for the CD-RW as hdd does NOT work with this setup.
