Extended content: What if my Vizio TV still won't recognise it?

If your Vizio TV still won't recognise your external hard drive, try checking the following:

Am I plugging the USB in correctly? Most Vizio TV have several USB ports, however there is usually only one named USB/HDD. This is the USB port you should be using. 
Have I selected the drive from my input list? Most TVs will require you to select your device from an Input list for it to be accessed. How to do this can differ from one Vizio TV to the next. If in doubt about how to do this for your Vizio TV, consult your Vizio TV's owner instructions.
Can I connect through another device? You may be able to connect your external hard drive to your Vizio TV through another device such as a Personal Video Recorder (PVR) that connects to your TV via an HDMI output cable. As well as facilitating a connection that may not otherwise have been possible, this device may have an in-built browser that could make navigating your files and using them easier on your Vizio TV. 
Am I trying to connect a USB hub? Many Vizio TV will support Mass Storage Class (MSC) USB devices such as flash card readers, digital cameras and external hard drives, but not USB hubs, so if you can't connect that could be your issue.
Are there several USB drives plugged in at once? If you have several USB drives plugged in at the same time your Vizio TV might not recognise some of them. Try unplugging the ones you don't currently need and keeping in the one you do. 
Does my hard drive contain file types not recognised by my Vizio TV? It's common for TVs to not recognise all file types, or at least as many as your computer will. This could be the reason you can't play certain files if you do end up connecting. If this is the case, to get your files to work you can easily convert them into a file format your Vizio TV will recognise.
