SD card problem

[riprull]

hey! today i just tried to download mega man legacy collection via hshop, and it appeared two errors, the firs one's code was 0xC960454C and the second one was something like rsa hash verification failure. Then i saw on reddit that i should check on the sd card status, i put it on my pc and doesnt recognize it, wich is weird bc i tried with the original sd card from the 3ds and it worked fine! what should i do?
pd sorry for bad english
pd2: my actual sd card is a 128gb one
pd3: oh my god i inserted the card again on the console and 90% of my games are gone, in fact, all the 3ds games are gone
pd4: im gonna loose my mind fbi, hshop and apps like that dissapeared
pd5: 3ds doesnt recognize the sd card.


nvm i asked on a dc and they said that kingston sucks basically

There are many, many, many, many threads at this point from people with similar problems.

It's not clear if your PC can still read your SD card. If it can, then the standard procedure is to copy everything off your SD card (Roadkil's Unstoppable Copier is recommended since there's a possibility of corruption), format the card, test the empty card with h2testw, and copy everything back again. If the test fails or if you can't format the card, then you should get a new card (and copy everything to the new card after formatting and testing it).

If your PC cannot read your SD card, then you might still be able to recover it with standard PC recovery tools. Easeus and Testdisk are popular. See https://www.reddit.com/r/3dshacks/comments/96kg4v/my_3ds_sd_got_corrupted_and_i_successfully/.

If you need to start over with a fresh SD card, then just follow https://3ds.guide/restoring-updating-cfw .
