Hi I recently purchased a SanDisk 1TB Portable SSD. The SSD does not show up as a disk in either the Finder (with External Disks checked) or the Disk Utility (with show all devices selected).

I have a USB C Hub, Type C Hub, Amkle 6-in-1 Adapter which, has both USB-A and USB-C ports so I was able to test the following:

  1. USB-C to MacBook Air 3.1 USB-C Port
  2. USB-C to USB-C Amkle Port
  3. USB-C to USB-A Amkle Port

Out of the three possible configurations, only USB-C to USB-A via the Amkle USB Hub works. USB-C to USB-C does not work through the hub or the Mac. The following is a screenshot of the System Report when plugged USB-C to USB-A (working) through the hub. enter image description here

The following is a screenshot of the System Report plugged USB-C to USB-C (directly to MacBook). enter image description here

Is there anything I can do to get USB-C direct to the MB USB-C port working? Note that I have tried a variety of USB-C cables that I have around.

    Try a different USB-C to USB-C cable. If your Mac can see a USB hub and device (using a C to A converter), the port works. The common denominator of 1 & 2 is the USB-C cable from the drive. In #3, you aren’t using that cable.

  • @Allan I have tried several USB-C to USB-C cables "Note that I have tried a variety of USB-C cables that I have around." Are there any sanity checks I can do to verify the cables should be working?

  • Do they work with other devices?

  • @Allan I do not have another device to test with

  • I'm starting to think that it may be the case that USB-C cables I have may not support USB 3 data transfers. I'm considering buying a Thunderbolt 3 cable to test this hypothesis.

Well turns out none of the USB-C cables I owned supported the spec required to plug in this drive. I bought this cable from Apple which did the trick, but any cable that supports USB 3 data transfer would likely do it.


It seems the USB C port on the hub only for charging. The product page saying the USB C charging port; (Support 5V/3A charging).

If you just want to use your SSD with the USB C cable, I recommend a USB C to USB C Data Hub.
Such as Satchi 4-PORT USB-C Hub. And make sure connecting the hub and the SSD with USB 3.1 Gen 2(or later version) cable.

Hope this help!
