external hard drive not mounting
Hi,
I have a 2012 MacPro OS X Lion 10.7.2 and a Silicon Power Armor A80 1TB portable hard drive. My portable hard drive used to mount (detected) onto my MB in the past, but not anymore. I connect the A80 via USB cable (attached pic). I have all (5 years worth) of my media (music, movies, pics) on the portable hard drive, and I want to avoid the need to wipe it clean and start over. PLEASE HELP!
Also, I am not very technically inclined, so if you can dumb down the details into lay terms, I will be so grateful.
Thanks,
Malaya
Mac OS X (10.7.2)
