If it is a parallel (ribbon cable) type of connection, then master and
slave configuring is essential.  Sometimes that's done by setting
jumpers on the drive, alternatively the drive can be jumpered so that
the ribbon cable sets which is slave or master (the ribbon connectors
are wired differently, with master on the end, slave in the middle, and
the connector that is furthest away from the others goes into the
motherboard.

But if it's a serial (SATA) connection, only one drive can be connected
to a host, so there is no master and slave arrangement.  With older
hardware, it's sometimes necessary to set a jumper which forces the
drive to run in a slower mode, or forces it to pretend its a smaller
drive than it really is.
