Being proactive on a ipod classic issue I'm having with my Avic head unit, but are there any external hard drives I should stay away from that I can connect via USB? I've got a couple notebook drives I've got in external cases I'm going to try, but the first one I tried this morning (not one of the notebook drives) was not able to communicate with the head unit. I got a USB error on the screen

A spinning hard drive might require more power than the HU provides.

Also, check the owners manual appendix for limitations on format, size, and the number of files.
