Issue with WD My Passport 2To

Thu Aug 14, 2014 5:49 pm

Hi, my Pi (B+) is ready to rock, with Xbian, but i can't get my external hard drive to work, even with Y-usb cable. Not detected.

Is there an other way than usb-powered hub, or i absolutely need it ?

Cheers !

:?:
Sorry, but that does not make a lot of sense to me. There are partial commands: '-t ntfs...'. That should probably have 'sudo mount ' in front of it.
Furthermore you assume it's a NTFS drive and there's a space in the driver name.
You have also thrown a bit of Dutch into it ('voor loskoppelen disk' --> 'to disconnect drive').

How have you checked? Did you use 'lsusb', which should give you all the USB devices.
If it is listed with lsusb you can use dmesg to see if a device is assigned. It should look something like this, but of course you could have an error message there

Though lsusb sees the drive conroller board, it may not be spinning up the drive..

The B+ has a default of 600ma on the USB Bus (4 x USB + 1 x Ethernet), I believe, many drives take more than this and could not find the details of the power draw of the Passport 2 TB drive but it seems to use only one USB Cable !

This may be worth reading if a mains powered hub also not supplying enough power:

As i don't really want to modify the usb voltage, what do you think about this "hub" ?
Can it be used good ?

You don't change the voltage, you're increasing the maximum available power / amps to the USB ports. Your power supply will have to support it too though; you would need a 2A PSU.

Which hub?

and, increasing maximum available is really safe for the Pi ?

Can you inform us of the Power Requirements of the WD PassPort 2TB Drive, I know it is 5V but what is the amperage ?? is it written on the drive ??

If its a WD Ultra(7200rpm)drive, you'll have to use a powered hub to run the drive. Then you shouldn't have any issues.

The title of the thread suggests it is a Western Digital Passport 2TB USB3.0 external USB drive !

The title of the thread suggests it is a Western Digital Passport 2TB USB3.0 external USB drive !
The"Ultra" line of WD usb drives use 7200 rpm drives, where as the regular WD line uses 5400 rpm drives. A 7200rpm drive would have a higher in rush of current than a 5400 drive which might be to much for a raspi to supply. If there isn't enough power the drive won't spin up and initialize, therefore it wouldn't be recognized by the pi, only the usb contoller would still be active. A powered usb hub will fix that, unless you just have a bad drive.

My drive is OK, it's recognized with all my others devices without any problem..
What i don't want in USB hub is to have additionnal câble.

I understand, my setup is somewhat messy, but with 2 1TB drives i have to use a hub. I used some 1/4 lexan and some stand offs to make a stack, that helps but there is no avoiding having a PSU, data cable, power cable, and 2 drive cables.

OK, so i'll pick up a hub. Raspiado & UUgear seems good alternative, or https://www.modmypi.com/raspberry-pi-ac ... pi-usb-hub but i don't know if compatible with B+

Oh i like that second hub :P thats nice with the same footprint as the raspi i have to get one of those! It would fit in my stack right under my pi and shorten it some. Thanks for the link!

The "naked" hub is the same size as a raspi, and the holes are in the same locactions. I screwed stand offs from an old pc into the lexan squares i cut out to make my stack and then mounted the raspi to the stand offs. I'll get a "naked" hub and mount it where my pi is mounted with more pc stand offs then remount the pi on top. My hard drives are stacked on top of each other each on a lexan square, then the hub then my pi with a square on top for protection. That will shrink the overall height of my stack at least an inch, plus it will allow for better routing of some of my cables. Makes for a neater tighter package.

After finally doing some checking turns out the mounting holes are not in the same locations. They are off just enough not to fit in my previously stated configuration.

Sounds like a cool installation !
Maybe you can post a photo, i'm interessted about it :)

EDIT : Max draw on each port of 1.2A ans max overall draw of 2.5A on all port - for "naked" hub
