Problem:
A WD My Passport external USB hard drive is not detected when connected to a Mac PowerBook Laptop, Mac Brook Pro, or Mac G4.
Cause:
Many 15" and 17" Mac PowerBook and Mac Book Pro Laptops do not provide enough power through a single USB port for the WD Passport(tm) external USB hard drive to work correctly. The WD Passport(tm) external USB hard drive requires a minimum of 1000Ma (Milliamps) of power for proper usage.
So Western Digital forces you to buy and additional power supply and/or cables for it to work!!! You can purchase a WD Passport(tm) Power Supply or a USB 2.0 Power Booster Cable from Accessories page on the WD Online Store. So that adds to the cost. PLUS, IF YOU HAVE TO BUY AN ADDITIONAL POWER SUPPLY, IT'S NOT AN EASY PORTABLE JUST PLUG AND GO DRIVE AS ADVERTISED!
