I have the new 2013 13" MBA (i5/8/128). When I turn it on without my external hard drive in, it boots in 11-12 seconds cold. But when there is an external HD plugged in, it takes closer to 30-40 seconds. Its not a huge deal but does anyone know how to fix this? I'm assuming that the Air is trying to see if it can boot into the external HD but I already have my internal SSD configured as the startup disk.
