Hacking I'm kinda Lost

[LPCC12]

Hi all, i dont know if anyone would be able to help me but if there's anyone capable it has to be here.

I had my 3ds for not even a year and Im getting alot of SD card related problems even with different ones...
I have a N3dsXl that i mostly use for Pokémon, i had a 64gb card gotten wiped suddently on boot... The card passed the tests and was really 64gb. I tought it might have been a rare situacion and reformated and done all from start... About 3 months later my card got wiped again but this time it broke... I dont know how to explain it but he only as 30mb and its formatted as "Raw" i talked to a friend and searched online and came to the conclusion that the SD card was faulty. Fast Forward to today and i have a new card (32Gb) but Im starting to have some problems again... I have my nds ROMs stop working for me (Twilightmenu++). The problem is that this exact thing appened days before the card first got wiped... Also i get this Crash every time i try changing theme (photo).

I know this sounds super dumb, and maybe i'm getting way to nervous out of nothing but if anyone cound give me a word or 2 i would thank alot.

Well, you'd better back up your card again (or at least your save data) if you haven't been doing that already.

Are you regularly taking out your SD card and putting it in your computer? After the first time an SD card went bad on me, I decided it would probably be for the best not to mess with it and do everything via MicroSD Management.

Since this new card i only took the card for setup and then stayed in the console until now. Also when i try to backup my SD card i am unable to copy the Nintendo3DS folder... I dont know why.. any other folder seens ok

So, are you backing up your SD card via MicroSD Management, or have you taken your SD card out now? This is unclear.

If you have plugged your SD card into your computer, and Windows Explorer is giving you an error message, then your card may already be corrupt. Considering the Nintendo 3DS folder is usually by far the largest folder with the most complicated structure, it is not at all surprising that other folders might still be easily copied.

You might still be able to copy files off using Roadkil's Unstoppable Copier.

Your Nintendo 3DS folder might just have some corrupted files in it - go through all the levels and if you see any file names with garbled random symbols (not just letters and numbers, they're fine), it is probably corrupted and you could try deleting the folder they're in, and try copying the whole Nintendo 3DS folder after that.

Hopefully you have been regularly backing up your save games with JKSM or Checkpoint and moving them to your PC.
