I have D-Link DUB-H7 with 7 ports. It works fine except I cannot use my external HDD with it. HDD clicks, but it seems not enough power. Connecting of 2nd HDD's wire doesn't help.

  • What's the model number of the HDD you're trying to use?

1 Answer 1


Anker 4-Port USB 3.0 Ultra-Slim Portable Data Hub with 12W Power Adapter - $16.99

enter image description here

Based on the fact that your HDD is intended to work with simply a single USB 2.0 port, I'm going to assume that it's simply a bit of a power consumption issue and a simple powered USB hub will fix your issues. There's a wide variety of USB hubs available, but this one is by a reputable manufacturer, comes in a nice form factor, works with or without power, uses USB to deliver additional power, supports USB 3.0, and is fairly cheap.

  • Nice to know name of reputable manufacturer, thanks, but my has 7 ports and 4 of them are busy without HDD, so at least 5 necessary. So I would go with 7-port Anker.

  • @RS Gotcha, didn't realize that 7 ports on the hub = 7 ports being used
