My computer has 4 sockets for SATA and 1 socket and a double cable for ATA drives, I notice my SATA drives have a small peg board (jumpers) similar to the master/slave peg board on the ATA drives, What is this used for are there any master/situations that I should take care of using SATA drives ?.

This post has produced zero replies as yet, I believe these connections are only used by the manufactures.

A bit of googling seems to suggest that different manufacturers use them for different things.
This seems pretty typical.

It appears from the PDF link "Bored chemist" put there, the jumpers control the way the drive is set up to "transfer data" by BUS speed of the accessory data links, e.g. emulate actions of speed up slow down physically the way an ATA does or transfer data at a particular specifications speed on the accessory slave CPU  data link BUS.
