So I just exchanged my 13" 2011 MBA for a new one due to some keyboard problems, and I just got home to restore the new one from a Time Machine backup. So I plug in my 1TB external HDD into the left side (if you're facing the computer while using it). The "looking for Other Computers..." thing keeps on spinning and spinning. Nothing found. After a few other attempts, turning the drive off and on, unplugging then plugging it back in, ect., I decide to try putting it on the right-side port. it immediately worked. Is my left side USB port broken? Anyone else have this problem?
