Semaphore is the Word for the Day

I connected an external hard drive that is normally assigned to the letter I but for some reason, my laptop assigned it to the letter D. That's not a concern to me as I know how to change the assigned drive letter. What is concerning is this never-before-seen-by-my-eyes error message:

I have zero idea where I set the semaphore timeout period or if it's even a setting I can manipulate. In fact, I had zero idea what the word "semaphore" meant until I fired up Google. That's where I learned the following:

Eventually, I will reboot my laptop and reconnect the external hard drive to a different USB port.
