As people have noted, Linux allocates two ide drives per
chain, just in case the system is ever fully populated.
This is especially entertaining on our XTR system since
the on-board South Bridge has two chains that we don't
use. This makes the removable drives e, g, i, and k.
As an obligatary piece of useful data, one reason we
rely on the Master disk on each chain is that IDE has
very bad failure characteristics for Raid volumes that
include Slave units. (If a Master fails, the slave can
get "promoted", with odd side effects).
