[Help Needed]: Power Adapter for MY BOOK WORLD EDITION II (BLUE RINGS)

Well firstly … the power requirements for a My Book World Edition is 12 Volts / 3.0 Amps / 36 Watts

Your 12 Volts / 6.Amps / 72 Watts power adapter is a bit overkill.

The “head” or connector size for a WD drive should be 5.5 x 2.5 mm

(WD documents say 5.5 x 2.1 mm but that’s wrong … one users experience)
