Hello!
I'm a little bit scared. I disconnected my external USB 2.0 harddrive once and when I wanted to connect it today (HD has an on/off switch, it was off, Mac was on) I heard loud popping out of my speakers and saw small sparks when I accidently touched the jack of the HD with the USB plug which was connected to the Mac. After finishing connecting it everything worked fine, my speakers still work and the HD is also undamaged. Could anything be damaged or is this harmless?
