Don't forget, there are ATAPI devices (some Sony CD burners and old phase-changers come into mind) which *do* have multiple LUNs sitting beyond the PATA port. I don't know if libata supports such setups (my old OS/2 driver does) but one shouldn't hijack LUNs to emulate targets.
It's a long time ago since I tested it but my 5 CD changer was correctly
supported by libata (or more accurately by sr...).

Well, sr supports the discovered CD/DVD; ch is the actual changer
manager.  Usually ch attaches to one LUN and sr attaches to another.

Like Alan's, if I understand him correctly, my PATA ATAPI CD changer simply presents a bunch of addressible LUNs. I never loaded, nor seemed to need, ch.

I should boot a current libata and see how it behaves...
