I installed Nexcloud on my Raspberry Pi 3B+ today and I want to storage all my stuff onto an HDD, but my problem is, that my PI couldn´t find my Storage. I tried different HDDs but it didn’t work at all. On my Windows PC each HDD is ok. Also, tried different formations, but no. The HDDs are connected with a USB Hub and all of them get external voltage. Even in the /dev is no hard disk. Tried to connect a USB-Stick, this time my PI recognized it and I could mount it.
Thanks for every help I get !
