I was watching a video file on my computer, paused it, went to resume watching the file and the external hard drive does not show up in my computer. It initially made a whirling noise for 6 seconds, then beeps repeats this process with the led flashing, now it is silent with the leds flashing. I went into disk management and the hard drive is not detected. Went into devices and my computer detects it as a hard drive storage device. Unplug it and the “my book” device goes away. How do I get my hard drive back as a hard drive?
