i have biab 2013 (MAC) ver. in addition to the mac, i have 3 pc's
(win 10, win 7) none of which will "see" the biab HD whenever i plug it in. bought the product in late 2013 and it worked fine up until nov '16 when i moved to my current add - my studio was dismantled and the HD unplugged from the MAC for approx 7 months.
whenever i set up my studio (05/2017) and installed the HD to the mac i noticed the prob. the pc's don't recognize it either.

anyone out there ever had this issue. at my wits end. any ideas or help greatly app.
