Well, it *is* possible to have four drives on the IDEfix adapter. That's why it is called a 4-way adapter.
Logically you should have them connected like this:
Channel1 -> HDD1 (master) -> HDD2 (slave)
Channel2 -> CD-ROM (master) -> HDD3 (slave)
But remember that there are three connectors on the adapter, two 40pin (for desktop drives) and one 44pin (for laptop drives).
So your setup (having one laptop drive) should look like this:
Channel1 (44pin) -> HDD1 (master)
Channel1 (40pin) -> HDD2 (slave)
Channel2 (40pin) -> CD-ROM (master) -> HDD3 (slave)
Or something like that. Just make sure that there is only one master and only one slave on each channel.
If the laptop HDD does not have a jumper to choose between master and slave, then it is likely that it does not accept another drive on the channel. In this case you cannot use four drives.
If you add or remove drives, don't forget to run HDToolbox and click once on each drive and let it save the changes it finds.
And finally, of course the drives on the second channel are only recognised if the IDEfix software is running.
Bye,
