SDD disk not visible in Raspi

  • I have issue to connect SDD to Raspi - initially I thought it is related to low power, but even when connecting it via USB hub this is still failing - any clues?

  • if it's an SSD that was previously connected to a Windows PC:

    - check if Windows was properly shut down. Not in suspend mode, not in hibernation mode

    - check for disk errors on the SSD if it is an NTFS or FAT partition.

    Otherwise, the USB caddy controller maybe somewhat allergic to Linux.

  • here it is:

  • I changed the hub to another one powered by 3A power supply and it is working now - I expected that RPI can handle SDD without additional power (I'm using 2A for powering RPI)? Would better power supply for RPI help here?

  • For me it works with that specific combo in combination with:

    Code
    max_usb_current=1

    I've used that RPi/SSD combination quite many times when travelling without any problems.

  • Ok, I can confirm, RPi3B+ powered with 3A power supply can directly use (without a hub) not only 500 GB SSD but also 1.5 TB HD (WD Elements).

    So for me this is perfect setup for travelling / vacations.
