Using external usb hard drive with toyota prius?

[ericblair1]

Hello,

Just got a new Prius with a USB interface. I want to buy an external HDD for music and books to use in the car.

Does anyone know if any external HDD would work or if the car software would recognize the HDD? Would I need to reformat the drive before using it?

Thanks!
