It sounds like my external hard drive might be failing. How do I make a 1:1 copy of it using my pc? Every time I plug it into my computer, nothing shows up.
It won't show up on a PC as the drive is formated in the WiiUs proprietary format that pcs don't recognise. Plug your current hdd into the wiiu and also plug the new hdd into the wiiu goto data management and transfer everything from the old HD to the new one. Be prepared this may take many hours if you have a lot of games on it.

But I'm not trying to move anything. I want to make a copy just in case it does fail.

With a raw disk imaging software, such as "dd"... but remember the external drive encryption key depends, on top of a value in the console's EEPROM, also on the hard drive's identification data and the USB interface's, so making an 1:1 copy is of questionable value - much better to backup your saves over FTP/SystemConfigTool/savemii and keep installation files for your installed channels

Or he can just do what I said above lol which is the easiest way but sadly takes the longest time.

Ok. I'll give that a try. Hopefully this a 1:1 copy where I can plug this in if my main drive ever fail. Thanks.
Yes. Also, as @Ryccardo said (but simplified a little) the encryption on the drive is actually dependant on the drive itself so just cloning the drive to another wouldn't work, the fingerprint of the drive wouldn't match the files, so the Wii U wouldn't recognize the drive.
But there is a way to read Wii U formatted drives on a PC. You can only dump the files (in decrypted format), copying them onto a new drive requires inserting said new drive into the Wii U, formatting it, and transferring the files over from a PC with ftpiiu_everywhere (which is a slow process). Also some keys from the Wii U are needed for the tool to work its magic.
Using the HDD->HDD copy feature of the Wii U is a much faster and simpler option. But if you did not have a second external HDD to dedicate to the Wii U, it would work in a pinch. https://gbatemp.net/threads/wfsdump-pc-util-for-dumping-wfs-devices-wiiu-file-system.478480/

Thanks again for the detail explanation. I feel a bit better now knowing I have a reliable backup option.

    lately I downloaded super mario galaxy for wii, but in the first phase, right in the first cutscene of the game, the game freezes in that part, with the image appearing but completely frozen. I already had this problem with pikmin 2 but in the end I couldn't fix the problem. Has anyone had this problem, and if so, did you find a solution?
