hda and hdb are first and second (master and slave) on the primary ide
channel. hdc and hdd play the same roles on the secondary. This would
imply that your cd-drive is jumpered as slave, which is wrong and 
shouldn't work at all (except in dos :)
So you may want to check the docs and jumper. cd-drives are often 
jumpered as slave by default, for easy connection to the same cable
as the (one) hd in most machines.
Adding a third hd may cause problems. Before buying you may want to
check this with an old or borrowed drive. If you do that, jumper it as
master and make the cd-drive a slave. You will be testing not only for
recognition, but also for power supply and cooling problems.
