Bumping or moving dock causes ejection errors

Thunderbolt TBT3-UDZ
1

Lately, when I move the dock a little, or even bump into, all of the drives I have plugged into it post an “Eject “name” before disconnecting or turning it off” error on my M1 iMac. I have done neither of those things. What can I do to eliminate those error messages? Thank you.

Hello,

Thank you for contacting Plugable support! Sorry to hear about this issue. I’d be more than happy to assist you.

It sounds like the Thunderbolt connection to the dock might be being lost momentarily when you move or touch the dock. Do only your drives disconnect, or do you lose video from the dock or other functions as well?

Does the Thunderbolt 3 cable connection to the back of the dock feel loose? If the cable is wiggled, not disturbing the dock itself, does that cause the connection to drop?

Please don’t hesitate to let us know of other questions.

Thanks again for contacting Plugable support and best wishes!

Thank you for your reply.

As far as I can tell, only the drives disconnect. I don’t use video, but I have an ethernet cable plugged in that goes to my iMac for the internet.

Just now, as I checked the plugins, all of the drives disconnected again.

It’s usually fine, unless I forget and touch it, or want to add another connection.

You’re most welcome. Thanks for the information! I believe that it may be best for us to try replacing the dock under warranty to see if that helps. Based on the information you’ve provided I’m quite suspicious of some kind of loose connection somewhere.

To do so, please contact us directly at support@plugable.com via email and provide us the following information (Do not post this information publicly here!):

  1. In the subject line of the email mention ticket number “349362”
  2. Amazon Order ID number or other proof of purchase
  3. Serial number off the bottom of the dock (will be located on a sticker with a barcode)
  4. Best shipping address

I’ll reply confirming it’s been received and I will then update you once the replacement has been shipped out.

Thanks!
Josh
