Needing to purchase a power supply for verbatim 500GB external hard drive

SOURCE: external hard drive doesn't respond

Shut your computer down. Disconnect you external hardrive. Power up your computer again. Power up the Verbatim and then connect to a USB port. You should hear a very quiet 'ping'.

Go to My Computer, and the Verbatim should be showing as one of your drives (probably Drive D). You should be able to open it from there.

Make sure that you have a Desk Top Icon for opening the hardrive, it makes it so much easier. Hope this helps

• Next check the hardware in My Computer > Device Manager if there are "yellow marks" for devices that require driver software to be installed.

When devices e.g. printer is connected before you installed the needed software, it can happen that the USB port is no longer recognized.
Then remove the device that shows having problems in the hardware manager.
Next install the software.
Connect afterwards or at the time the computer asks to do so.

Hello

A few questions that may confirm problem.
Does your computer seem to know that something is plugged in?
Or does it say that it does not recognize the device?

Well, if the computer actually knows that a device has been plugged in, but you just cannot see the device in my computer, here is how you fix that. Just follow these steps:
Control panel
Administrative tools
Computer management
Storage
Disc management

Now you should see your device presented in the schematic below.
Right click on the device and assign a new drive letter.

If your computer states that it does not recognize the device, try plugging it in one of the back USB ports of the computer. Please rate this.

Best regards
