Hi,
i am trying to get a WD 2,5'' usb disk working on my Pi2.
the light on the disk is on when i connect the disk but i cant find the disk in the Pi2
the only thing in the usb ports are the dongle for the remote control and this WD 2.5" usbdisk
so can this be a powerproblem or am i doing something wrong?
thanks

What happens when you connect this disk directly to USB port on Pi?

I'm not terribly familiar with OE but I'm sure they would automount drives. You should probably ask on their forums.

If it's not auto mounting then yes I would strongly suspect it's a power issue.
I have a WD MyPassPort drive which was very random in whether it was seen or not (and whether both it's virtual CD and main partitions were mounted or just the vCD one) when just straight USB powered, but as soon as I put a powered hub in there it mounts every time without issue or failure.
You can try adding max_usb_current=1 into /boot/config.txt to enable maximum current through the USB ports (depending on what version you are running it may already do that by default), but I'd recommend looking into a powered hub (which can also be used to power the Pi itself if you get a good one).

I would get a external USB with additional power connection. Hard drive needs about 1 amp to get it going... External power source is needed.
