Wii U USB Helper downloading corrupted files

[SnowyVul]

For whatever reason, USB Helper is downloading my game files just fine, but when I go to transfer them to my Wii U's SD Card, suddenly they're corrupted and I am unable to transfer them. They only get corrupted once I try to transfer them.
My SD Card and USB are both in firmly, USB Helper fully downloads the games and I have no issues downloading the game itself. If it's relevant at all, I'm downloading Kirby's Return to Dream Land. Yes, I removed the apostrophe in the file.

How do you know they corrupt while transfairing them to SD?
What SD card are you using and where did you get it from?
What CFW are you using?

You should probably test your drive health before you come to the conclusion that said files are corrupted.

What I recommend doing is switching over to FunKiiU (because lets face it, USB Helper is sub-par) and directly copy the downloaded files to your SD Card; or alternatively try an installation using NUSspli. Try it with a relatively small game, 500 mb - 1 gig as a general test and monitor the process of the installation.

@V10lator brings up some crucial trouble-shooting points also. How do you know they're corrupted? Could it be due to an unstable connection? Whether it be from simply downloading them, or via transfer? Is your SD Card reaching it's death limit? Because it very well could be while still appearing functional.

What type of SD Card is it? Is it equipped to handle the amount of writes the Wii U passes to it? Does it have credible life-time, durability, and sustainability?

What CFW are you using? This can largely impact how we may be able to assist you. For example if you're using Tiramisu or Aroma, it might suit you to try NUSspli as it's probably the most reliable NUS Downloader so far.

Using File Explorer. When copying over to my SD Card it says a multitude of files are corrupted in the folder of the game, but USB Helper would've given me that warning already.
FAT32 formatted SD Card, and I'm using Tiramisu.

What is it? The windows file explorer?

FAT32 formatted SD Card

What brand and where did you get it from? Well, forget that as the previous reply sounds like a fake SD card, so go straight to checking the card with https://3ds.hacks.guide/h2testw-(windows).html

Replied to the person above already about your first question, File Explorer explicitly says the files are corrupted.
Honestly, I'm not sure how old this SD Card is. It's at least as old as, what, 7 years? I used to use it with a now broken down 3DS but formatted it to use with homebrewing my Wii U.
Tiramisu is the CFW.

Most likely the card reached it's write limit, or it was an off-brand; in which case those especially under the amount of stress a Wii U can put on them tend to deteriorate or corrupt files rather quickly.
