Answer 1

I am not sure why you get that error. One thing you can do is a SMC reset then try to format it again. However that being said I'm not fan of WD external HD's primarily because we see a lot of troubles with them on Macs. Their internal HD's are fine so that narrows it down to their enclosures. If the problem persists I'd return the drive and buy one of the following:
OWC (www.macsales.com) Mercury Elite Pro series
Lacie Quadra d2 series
G-Tech G series
SMC RESET
• Shut down the computer.
• Unplug the computer's power cord and all peripherals.
• Press and hold the power button for 5 seconds.
• Release the power button.
• Attach the computers power cable.
• Press the power button to turn on the computer.
PRAM RESET
• Shut down the computer.
• Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
• Turn on the computer.
• Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.
