Windows 10 map to Airport Extreme USB hard drive
I have a USB hard drive I would like to use as backup drive for the Windows 10 laptops in the house. Currently, the hard drive is FAT 32 and my iMac recognizes both when it is direct connected and when it is connected to a USB hub attached to my Airport Extreme. My Windows 10 machine recognizes it when attached to the the laptop.
When I connect the HD to the AEBS and try to map to it from the Win10, I cannot see it. I have tried to map to it using "Map Network Drive" in Windows. I have also tried to use Airport Utility on Win10 as well as Mac. Under "Disks" in AU, I do not see any "partitions" from either my attached TM drive or the Fat32 drive. When I go into "Get Info", I can chose "Shared Folder", but I don't really know what to do with that when I enable it in System Preferences. Regardless, even with those selections, I do not see it.
Therefore, the bottom line question is "how do I connect Windows 10 to a USB attached drive on an Airport Extreme?"
