Maxtor USB drive not recognized when UD-160-A plugged in

I use the UD-160-A with Windows 7 on an HP Probook 450 G3. When the 160 is plugged in, Windows will not recognize my Maxtor USB drive. All other USB devices are recognized, whether they are plugged into the 160 or into the laptop itself. Suggestions?

Hello Tony,

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

If your Maxtor drive is USB powered (vs having its own external power supply) our dock may not have enough power to spin-up the drive.

I’m assuming the drive works correctly via the laptop if connected directly?

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

Thanks again for contacting Plugable support and best wishes!

Thanks for responding so quickly. The Maxtor drive has its own power and, even so, I am plugging it directly into the laptop. (Plugging it into the docking station results in the same error. Just as well, since I am out of ports on the docking station.)

What I have noticed since I posted this: If I unplug the docking station from its USB port and then plug the USB drive into its port, then Windows recognizes it. Then, if I re-plug the docking station into its port, Windows still recognizes the USB drive. So, I guess I have a work-around. If you have any other thoughts, I would like to hear them. If not, then at least this post might help someone else.

No problem Tony! Sorry for my delayed reply. I’ve looked through our support tickets for similar issues and I’m afraid I don’t have a better solution to offer as a work-around - though I am glad you found at least a workable “fix” for the time being. However, we could try to collect some additional diagnostics to see if there’s anything that can be done to fix the issue from a software perspective.

We have a troubleshooting tool that helps us find out what is going on in situations like this. Please plug the drive into your computer when the dock is already connected (thus being in a problem state), then go to this page and follow the instructions there:

I’m not sure if I’ll be able to find anything conclusive, but happy to take a look!
