I have a My Book World Edition (white light), with a secondary WD 3 TB hard drive attached to the MBWE USP port on the back. the My Book World Edition is recognized by Finder, but unfortunately there is no display for the secondary 3 TB hard drive in finder. Running Mac OX 10.6.8. I thought that you could plug an additiional USB hard drive into the MBWE and have it recognized automatically - help is much appreciated!
I believe you can not connect a drive larger than the MBW through USB
this might be the reason why the other drive does not appear
try going to the net admin an formatting the external drive //mybookworld
it will show under advance mode > storage > usb shares
