Data still in storage after factory reset I am trying to sell my Note 3 and performed a factory reset both from the Home + Power + Volume Up menu, as well as the settings -> Factory reset menu.

Both approaches seem successful at resetting the device as nothing remains on the phone's interface and I go through all the screen like the first day I bought it.

The only issue is when I connect the device to the computer via USB, it appears all the data is still in storage, just not on the user interface of the phone. Any idea why this is? 

I would like to completely wipe everything off the phone so the storage is as empty as it can be.
If it is an external storage try formatting the external SD card. You can do it in the computer or in Android it should be under Storage.
