Weird... Yesterday, I put it in, to backup my saves for Etrian Odyssey, MMSF2, and etc, but it didn't auto-boot like it usually does, so I went to "My Computer" and opened up the volume... Nothing was there, thinking it was weird, I put it back in my DS, and the mini-loader showed a bunch of folders with jumbled letters, none of which did anything. Recuva didn't help to get back my files either, as everything was completely wiped. So I formatted it to be safe, put my stuff back on, and proceeded on with playing my games when I was bored... Today, I put it in, backed up my saves, took it out and it worked just fine. Later on, I went to add a new game to it, but when I put it in my computer, everything was gone once again. I checked the mini loader, but this time, all I got was a black screen and nothing happened no matter how many times I tried. So I formatted again... Fortunately, all that was lost was my Niece's Princess Peach save file, of which she only lost one or two levels of progress, however, will this happen again? Can somebody tell me what's going on? I was using the M3&G6DSReal firmware version 3.8 up until now, and noticed the website now has 3.7e back instead, so I downgraded, thinking maybe it was the system files? I don't know. My card has been wonderful all this time (It was my first flashcart, and I ordered another for a friend who's in the hospital right now.) and both of ours have been perfectly fine. I read in another topic to charge my card, so I left it in my computer for a few hours yesterday thinking it might have helped, but apparently not... Any idea as to what's happening? tl;dr: Everything gets erased when I put it in my computer every now and then, and I'm forced to format and re-write everything.
