I have the following configuration: A Raspberry Pi model B connected to a powered USB hub, with the +5V detached from it (otherwise the hub powers the Pi due to backfeed). They work fine together and I can plug in many hi-powered devices, such as wifi adapters.

I want to connect to it an unpowered external western digital harddrive. When I plug it to my laptop it shows up as:

1058:1010 Western Digital Technologies, Inc. Elements External HDD

However, when I plug it to the powered hub on the Pi it shows up as:

13fd:160e Initio Corporation

The /dev/sdd file is not created. It is inaccessible.

I will note that if I connect the powered hub to my laptop, with +5V removed it also shows up as Initio Corporation. So this probably not a Pi specific problem, but due to it I can't access this drive with my Pi, as I would like to.

How can I get this drive to work with my Raspberry Pi.

I got a 2.1A power supply for the USB hub and now it detects it correctly. I guess the drive draws more than 1A of power.

From Initio Corporation:

Initio is a leading provider of quality cost-effective integrated circuits and solutions for storage devices.

Inside of your hard drive's case is an Initio logic board (some call it the USB-SATA bridge board) which has its IC (microchip) installed right on the drive. This is what your Raspberry Pi is communicating with.

From what I can read up on, it seems to be a driver issue, power issue, or formatting issue:

  • Take a look at Google to see how to install the drivers properly.
  • Some Western Digital hard drives have their own power supply, so you could plug in the hard drive directly into the Pi with the external power supply to see if that fixes it.
  • Make sure that the Raspberry Pi can read from the filesystem used by your hard drive.
