I have been using VMWare Fusion 8 for a few months now. For the most part, Windows 7x64 works great with it. When I plug an external HD into the USB port, I get asked if I wanted to connect to the MacOS or Windows.
Mac never (ever) has a problem.
Under Windows, it sometimes works and sometimes not. What often happens: no drive letter appears, but: if I click on "Safely remove hardware and eject media", one of the item is see is: "Eject External USB 3.0". So, Windows is at least partly aware of the drive
I've never seen this on a machine natively running Windows, so I strongly suspect it to be some interaction between Fusion and the Windows 7 guest OS. If I knew how to go about it, perhaps I could manually assign a drive letter.
Any help on this would be highly appreciated
cheers,
