Dock not recognizing 4tb seagate drive.

i have like 3 drives that i connected to this dock with no issues. i purchased a seagate 4tb barracuda and it recognize it. is there anyway to even troubleshoot this thing?


Thanks for contacting Plugable! Sorry to hear that your USB hard drive dock is not working as it should. First, I would test that hard drive in another computer to confirm that it’s a healthy drive.

Here are links to get started depending on which type of hard drive applies to you. Let me know if any particular step is an obstacle.

For new hard drives:…

For hard drives with existing data:…

Next, there are a few troubleshooting steps that you can perform to isolate the cause of the issue:

  1. Test the same hard drive and dock in a different computer to eliminate any potential issues with your current computer

  2. Test the same dock with a different hard drive in the same computer to eliminate any potential issues with your current hard drive

  3. Test a different USB cable with the dock if you have one available to eliminate a potential bad USB cable

If the issue seems to follow the dock after the above troubleshooting steps, it may be defective. In that case, please email with the following information:

  • Order ID (for example, Amazon order ID’s can be looked up via
  • Shipping address

Let me know what you find out and I can provide next steps!

Thank you,
