External USB 2TB HD not spinning up.

I have a WD 2TB external USB drive. It mounts fine on my linux laptop. When I plug it into the beagleboneblack, it times out. Any help would be appreciated!

sounds like its exceeding the power draw

spinning up and nothing.

If it is drawing too much current, I suggest a powered hub between BBB and HDD

The HDD is USB 2.0 which means max 500mA, but BBB can only supply 100mA https://github.com/beagleboard/beaglebone-black/wiki/System-Reference-Manual#usb1-host-port

The format is Microsoft NTFS, which Linux cannot repair

Thanks for the help! I really appreciate it! I’ll check out a powered hub

A further note of interest. I experienced this problem when the BBB itself was powered by USB connection to my laptop. However, I discovered that when I plugged the BBB in with the power adapter, the external USB drive spun up no problem.

Is this expected behavior? Just curious. Thanks for the pointers.


  • What power peripherals are required/desirable?
    • There are several ways to power a Beagle. The option exists to feed the on-board regulators through either the 5V barrel connector input or USB input. When powered up over USB, the regulators are somewhat limited in what they can supply the system. Power over USB is sufficient as long as the software and system running perform some management to keep it under the USB current limit threshold. For simplicity and maximum capability, powering over the 5V barrel connector is typically recommended.- The power adapter is required to provide 5V over a 5.5mm outer diameter and 2.1mm inner diameter barrel connector (a barrel connector length of 9.5mm is more than sufficient). The recommended supply current is at least 1.2A (or 6W), but at least 2A (or 10W) is recommended if you are going to connect up anything over the USB. The actual power consumption will vary greatly with changes on the USB load.

I vote for using a Powered USB Hub attached to the BeagleBone. I’ve had to do the same thing when using a separate Bluetooth and WiFi module and for just basic USB expansion. However, I found that not all Powered USB hubs worked with the BBB; at least not so a few years back.

I did have luck with the Belkin P-F4U041 though:



My experience,

I have had a BBB powered with an external 2amp supply with an external ssd plugged into usb port for over a year with no issues. In the last several months or so, the drive was not available via samba at least twice a week, had to reboot BBB to get smb drive back. added a powered usb hub for the ssd, and all is back to normal.

do updates on this system every so often.

I know this is not a one to one, but maybe it helps.
