If a touch the USB Drive, it disconnects and if I touch it again, it'll reconnect. This is not a Windows or OS issue, is a port/connector issue. I think some of the peripheral cables have a somewhat smaller or thinner enclosure that does not allow the connection to be firm. Step 1. Cut your computer power at its source, which is unplugging your computer from the wall outlet. Step 2. Leave the computer unplugged for a few minutes, and then plug it back into the wall outlet. Step 3. Check if the computer detects the USB device and assigns it a drive letter. Ever since I upgraded to Windows 10, every now and again the front ports of my PC case would disconnect, and anything plugged into them I would have to unplug and re plug back into the port (mainly my wireless network adapter), but now it has also started happening on the back of the case. Back in November, I built myself a Windows 10 20H2 computer that is operating as a "server"/host for various applications. Every now and then, the PC's wired NIC will randomly disconnect from the network. This PC is headless, so to resolve the issue, I simply unplug the Ethernet cable and plug it back in and then it suddenly comes back to life. .
