Had something wierd happen today with on of my SD cards.

There's a lot of shenangians going on over here trying to find an SD card for 40GB of data that I simply didn't have any SD cards for. They were either too small (32GB), or FAR too large (512GB). I found a 200GB one I could use and copied the 3DS data to it.

And it promptly failed. The 3DS would not see it, or would see it, but couldn't recognize it. I'd put it in my PC, and the both Linux and Windows could see it just fine: a 200GB SD Card formatted in FAT32.

I had it checked with F3 to see if it was a counterfeit card (I had to deal with a LOT of counterfeits at NOA, where they'd bought a 2TB card (which didn't exist at the time) for $10 (really?) and in reality it was a 2GB card hacked to read 2TB.), and it was a proper 200GB card.

I kind of gave up on it, and put the data on my 400GB card (wasting 90% of it's current capacity), and put the 200GB card in my laptop to format. It also saw the card, but couldn't read it correctly. It was the correct size, but the format was "Unknown."

So I had THAT Linux format it in FAT32, and it recognized it, and so did the 3DS. But why would it work on my PC just fine before?

Don't matter - I've got a 64GB card coming in tomorrow, so I can clean out the larger SD cards and use them in something that could use the space....
