Hacking Weird WiiFlow files?

Stargazer58 · Jun 22, 2022

I deleted WiiFlow from SD Card but there was still cache files. They have weird names and windows says they are system files and I shouldn't delete them because windows or other programs might not work. I think they may be corrupted because of the odd name and the file sizes are bigger than my SD Card. Should I delete them?

Format the card. I've had this happen with USB flash sticks before I moved to a USB drive.

I would but this is the SD Card that has all my homebrew files on it like apps. I do have a backup of the system should I restore that or reset all my homebrew?

Run this from a Command Prompt (right-click and run as Admin):

chkdsk x: /f

Replace the "x" with the SD card's drive letter. This will check the filesystem for errors and attempt to fix them.

However, this sort of random file garbage is usually indicative of bad or fake storage media. So after running the above command, back up everything to your computer and then do a FULL format of the SD card. Don't do a quick format. And then test the SD card with a tool called h2testw. If the test lists any errors, the SD card is permanently fucked and you should throw it away. But if it passes the test, copy everything back to it and you should be good to go.

EDIT: Corrected the h2testw link.

I'd copy everything but those files off it firstly. Then format and put them back.

I think my SD Card is broken because while attempting to copy 30 MB of my apps folder the ETA said "4 hours ~ 13 hours". Should I just format or keep trying to back up? It also takes a while to eject from my computer and the window its in constantly stops responding.

Yeah sounds like the SD card has had its day.

What other files do you have on the sdcard other than those?
Use Roadkill's unstoppable Copier to copy what's left of those files (not the ones that're shown in the screenshot above) and store them in your pc.
Then format the sd card as Fat32, and test it with h2testw with (write & read) setting.
If it doesn't pass the test, then it's faulty and you need to het a new replacement.
If it does pass the test, then format it as FAT32 32KB cluster size, and put NEW Homebrew Channel, USBLoaderGX, BootMii etc. files on it.

The SD card won't even format anymore so it's definitely broken, I can't even view it anymore. Thanks for your help.

That's usually what happens when flash storage (SD is a type of flash storage) reaches its write limits. Certain things such as using it in mobile devices/tablets where apps constantly write to it, or as an external drive on a Wii U console can make this happen faster. Basically, you want to avoid writing to it too many times if it can be helped.

And sometimes you just get a bad one.
