It's not self evident to me that one naming convention is better than
another. Why does it make more sense to you to call something a
hard-disk, even if it isn't ? The standard IDE drivers use the naming
conventions that they do because there are a small number of physical
slots in which a device can be located (primary/secondary, master/slave).

The parallel port IDE drivers support chains of adapters on
the same port, up to six different ports, master or slave on each
_adapter_, as well as LUNs - all of which adds up to something much
more like the SCSI subsystem, on which the PARIDE design is loosely
