New USB Drive Doesn't Show on Network

I'm running Windows 10 version 1909 on a couple of refurbished computers; a laptop and a PC. I have them connected together on a Windows Home Network.

I just bought a USB hard drive which I plugged into the PC. On the PC it shows up as drive E:, (in fact, oddly, it shows up twice) and it also shows up on the network listing in Windows File Explorer on the PC as E (without the colon).

But from the laptop, it doesn't show up at all in the network listing for the PC.

I believe I've set the USB drive to be shared. Is there something else I need do so that that the laptop can "see" the USB drive connected to the PC?

(Over the last couple of decades I've learned that Windows often takes its time finding new devices added to a network. So for now I don't know what else to do but just be patient and wait to see if the new drive finally makes an appearance on the laptop).

Thanks for that speedy and detailed reply, thomaseg1!

I've been away from my computers for the last hour, and just now took a look at the network listing on the laptop, and guess what?

That's right! Drive E from the PC has mysteriously appeared in the network listing on the laptop.

So I apologize to you for putting you to all that trouble, when the solution turned out to be: "Just be patient. This is Windows networking after all, and as we all know, Windows networks are notoriously slow on the uptake."

Thanks again for being Johnny on the spot. This is a great group and I would be lost without all the help I get from you folks.
