I used this on my Windows 7 x64 computer to record to three 64GB microSD Samsung memory cards. It's really plug and play. However, I should note that while I haven't been able to verify that only one card can be viewed at a time, since there is only one card for the same slot, when plugged into a USB port, it does tell about the presence of all four removable drives for Windows and display them at least in the "My Computer" window. So I assume it's a feature. The activity indicator it claims to have is a tiny dot of blue light that pulses when it has a card, but that's a very bright blue light considering how small it is.
