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.
And now it's mounted for no apparent reason., haven't done anything different and it's gone straight on.
