I have a USB powered external hard drive. The cable that came with it has to plug-ins for the PC. I know the fat one provides power so I use that one. I would like to know what the other skinny one is for.I have seen other people plug both in when using it and it worked fine for them. I am using just the fat one and it works fine for me. I would just like to know the reason for having both on a cable.
to give the end user another alternative to connect the drive to the pc if there is no usb slot available or free
Two sizes are the same connections, standard and mini. Use whichever fits your computer.
I would stick with just using the one cable (the fatty). I would think that having both plugged in would cause issues with getting confused.

The Fat one is the Main one. If your computer is provide most power the HDD needed. That would be just fine. Just like on your case. The Skinny one is the Extended for getting extended power needed. Thus if some computer could not recognize your device, mostly caused by unable to get some power. You could plugged it both to get suitable power for your device.
