Hi

Just a question that will probably seem silly to many.

Can simply plug an external hard drive in USB or will there be power problems?

Thanx

If the power supply of your A20 board allows it, and if the hard drive can get properly powered by the UBS - it should work.

What exactly is the hard disk you have in mind? Maybe I can check its specification.
