Hacking What is causing my MicroSD to corrupt?

[Terrum]

I have a genuine Sandisk 128GB MicroSD which I have tested with h2testw and formatted fully (not quick) on multiple occasions, using FAT32 and 32kb cluster size.

Very rarely it will freeze/crash when loading some CIA games, and during such it will corrupt one or two files. Not too horrific seeing as I have a backup of everything anyway.

But now it's getting to the point where it's beginning to corrupt whole folders, having cross-linked allocations, and now even worse - corrupting the whole drive (SEE SCREENSHOT ATTACHED!)

This is not a fault with the MicroSD card as I have tried 3 different ones, and all of which have been heavily tested and having no issues on other devices (used the same MicroSD cards in cameras, phones, etc).

I have suspicions that TWiLightMenu might be causing the corruptions for some reason, as it seems to occur more within that software. Because I have the new 3DS I tend to use FTP to transfer files where possible. I'm using different adapters and scan the drive for errors right after writing any data - it's definitely the DS (or its CFW or some installed software) that's causing the corruptions.

Running 11.13.0-45E. Any help is greatly appreciated.

Have you used h2testw to actually check if the sd card is corrupt or dying? It dont matter what you say here. Check it with that and see if there are any errors. And it will be a full read / write. so make sure the sd card is fully empty and backed up before doing so.

Hi lone_wolf232, thanks for your reply!

With all the MicroSD cards I've used I always select 'all available space' on h2testw and perform a 'write + verify'. I also ensure the cards are fully formated (empty) before doing so.

The only other options available are 'verify' and 'endless verify'. This Sandisk one is brand new (delivered today from Amazon) and encounters the same issues as my previous MicroSD cards so I'm certain it's not the MicroSD card nor the previous MicroSD cards.

MicroSD data corrupts on the 3DS, but h2testw comes out fine

Thanks TurdPooCharger, as I have already tested with h2testw the only other relevant posts in that thread mention that TWMenu is likely the culprit, in that case I'll remove it and see how it goes from there.

I'll also report the issue on the official thread, as it seems other people are having the same issue with 64GB+ MicroSD cards.

We might need some info on which version of TWiLight Menu++ you're using (perhaps upload and send the _nds folder, boot.nds, TWiLight CIAs that were installed, etc), games that were being played, 3DS system, firmware + CFW setup, and SD card format settings. I'm willing to be a tester to try to recreate this bug once I have enough free time later this month.

The OP of the official thread is already aware and has made a warning on the first post now. But I'll be happy to help where I can.

I've been using the latest version (v12.0.0 Valentine's Day release), the boot.nds, CIAs etc would therefore be the same/untouched copies used in the latest version (same as the download). New 3DS XL with Luma3DS firmware 11.13.0-45E. Sandisk 128GB, FAT32, 32kb cluster. I only have 3 games installed (Super Mario 64 DS, Mario Kart DS and WarioWare Touched - all Europe versions).
