Switching out Hard Drive

I recently bought a new hard drive for my computer, and I wanted to transfer all of my data over to the new one, but I've been running into some issues remembering how to do it.

The new drive is a 640GB WD Caviar Blue, and the old one is also Western Digital. They are both SATA drives.

I first plugged in the new drive and formatted it and installed my OS, but now I can't recall how I get the data from the old to the new. I seem to think that I need to somehow set the old drive up as the master and the new one as a slave, and that to do so I would use a jumper to cross two of the pins on the back of the drive, but I don't have a jumper(none came with the drive), nor do I know where to get one, nor the configuration I'd use if I did have one.

I tried just hooking them up once, but to no avail. I have the single power strip hooked to both, and 2 data cables each hooking a drive to the mobo, and I have entered the BIOS and activated drive 1 in addition to drive 0.

Also, once I do get a jumper or two, what's the best way to transfer my crap?

Ah, I made a rather silly mistake. I didn't realize that my computer had 4 slots for data cables and plugged into slot #2 thinking it was #1. Now I've got it straight. All solved.
