With a hard drive how do I master...

Ok in an attempt to save my information I'm gonig to try out some recover software rather then pay the butt-raping price of a dagta recovery service ($500-$2700) so I need to know.

How do I go about making one hard drive the slave and the other the master?

If you look at the back of the hard drives, there should be a piece of plastic covering two of the pins between the IDE connector and the power connector (it may be different if it's something like SATA).

On top of the drive, there is usually a label containing the jumper settings:
