Western Digital Elements 120GB USB 2.0 External Hard Drive ($25 f/s newegg)

No external power, so it would work on a car stereo with a USB?
 
That's exactly what I want to know. Thinking of getting it for my father-in-law to plug into his JVC car stereo.
 
^ I'm sure it just depends on how much amperage the particular unit is capable of pumping through the USB port. Some may work, others not.
 
Many external 2.5" drives will either always or will eventually require a double cable because they need 1000ma rather than 500ma, and don't expect to use them at all from unpowered hubs.
 
i bought this for a car last time it was posted. it worked great on my pioneer deck, and it worked great on a honda with integrated usb.
