Hi. Unfortunately, With the later versions of the passport, there is no allowance made for an external power supply. The new Toshiba drives, which look a lot like the passports also have no power supply port. They are both powered by the USB port on your computer. -----Original Message----- From: icon-discuss-bounce@xxxxxxxxxxxxx [mailto:icon-discuss-bounce@xxxxxxxxxxxxx] On Behalf Of Marc Mulcahy Sent: Tuesday, April 15, 2008 4:51 PM To: icon-discuss@xxxxxxxxxxxxx Subject: [icon-discuss] Re: Anyone Successfully Using Western Digital Passport Drive? Many USB drives aren't specifically USB spec compliant and require an external power supply. I expect that may be the case if the drive starts and stops. USB says that a device can only expect a certain amount of power if it is connected to one port. Many USB hubs, including those inside laptops, have multiple ports, and make the total power for all the ports accessible to a single device like a CD ROM drive or hard drive.
