Give me a big DERP. I simple router reboot with the device attached solved the problem.
I have a My Net N750 and I’m trying to connect a USB hard drive (I’ve actually tried 3). None appear in the list when I follow the “Set up Storage” wizard. All three drive have been working on various computers for quite a while and are recognized by other computers when I moved them for testing this problem. Two are Mac formatted and one is NTFS. Thanks.
P.S. I also tried reformatting one of the drives. I tried both NTFS and Mac Extended (Journaled).
