I'm having a bit of trouble getting my WD MyBook Duo to mount on my Pi. I've successfully mounted a 256GB USB stick but this 4TB enclosure doesn't seem to want to mount and I'm not getting any errors. I can see the drive and partitions in lsblk sda2 exfat 3.7T which is all correct. I've got my mount point setup at /media/exfat and I mounted the USB stick there and it worked fine. When I try to mount with sudo mount -t exfat /dev/sda2 /media/exfat I get the line FUSE exfat 1.3.0 (just like with the USB stick) but then the drive still isn't showing in df -h and if I ls /media/exfat it's empty. I'm assuming that because the Duo is powered by a mains brick, it doesn't need a powered USB hub, it's whirring away and the lights working and I can see it so I assume that's ok. Any ideas? *EDIT* Tried using a powered USB hub and it didn't show up anywhere. Unfortunately, now I've plugged it straight into the pi it's still not showing up.
