Hello,
Every time I plug in my external hard drive my pc can recognize but is unable to load it and it crashes the file explorer. and turns my background black. When the background is black I am unable to access anything until I unplug the external hard drive. None of the crazy stuff happens until I 1. turn off then turn back on my pc 2. is clicked on in file explorer. Please help.
