External Hard Drive won’t shows up in My Computer

I think the issue started when I plug my Ext HD in my tablet. When I plug in it in my PC it can’t be viewed in My Computer (File Explore) but it was in the Safely Remove Option. It can also be seen in Device Manager and Device and Printer in Control Panel but not in Disk Manager. I also tried uninstalling it but it didn’t work. Any help or suggestions. Thank you.
