This has been a bizarre week.
So, I have a 128gb Samsung microSD card. I've had it for years and it served me well through my previous 3DS, my Switch (until I upgraded to a 512GB card) and now I put it back into another 3DS I bought recently.
After I setup the 3DS with CFW I went and installed a bunch of games, including custom VC injects and DS roms which I load via Twilight Menu. Everything worked.
A few days ago I went to turn the 3DS on and it got stuck on a black screen with the blue LED on. A quick google search told me to run the "remove extdata" script and so I did. The 3DS booted and I thought nothing of it, until I realized some of my games wouldn't run anymore. They would crash on boot with ErrDisp messages.
I reinstalled the games and then they worked fine, but after I ran Twilight Menu I started noticing some of the ROMs had incorrect file sizes, and they too would not run. And when I tried to replace those ROMs, data would corrupt elsewhere.
My assumption was that the card became faulty, but after I ran a full 5 hour write+verify using h2testw, the card came back clean.
So now I have to ask what the hell could possibly be causing this?
