mojave no longer recognises exteral har drive on router
Imac, late 2015, running Mojave version 10.14. 3
Router; Asus AC 1900.
Router connected to mac via Ethernet, to all other devices in network via wifi.
Have a 2TB external hard drive attached to the router. This has meant I can access the drive on all of my devices. I recently disconnected it incorrectly. The result is the Mac now cannot find the drive. No problems with any of the other devices.
I have rebooted both the Mac and router a couple of times. I've obviously done something stupid. I'm hoping the solution is not too onerous.
I want the external drive accessible by the Mac so I can add files directly. I can possibly do that via my Windows laptop, but it's a lot of messing round.
