I edit lots of movies. I have a FeeAgent external hard drive and store all video on it. It has always been the “F” drive. My mouse quit working and I got a new hp wireless mouse. I plugged the USB part into the computer and the mouse works, no software installed. I opened a video project and my external hard drive is now “G” drive. I cannot open any of my video projects because the editing software is looking for the file in the “F” drive. I had an SD card in the SD slot and now it is the “F” drive. I shut down and started back up, same thing. I shut down, unplugged all USB devices and started back up. I began to plug-in my flash drives to see their drive letters. My SD card that was “F” was not in the SD slot and the first flash drive name was “F”, same as the SD card was. The next flash drive was “G”, and the next was “I”. I then plugged in my external drive that was “F” and now is “G” and now it is “J”. What is going on? Can I change the name of my drives? Jimith
