I dont know how it did it, but it did. I just got my CycloDS evo Black (3 day shipping from ModChipCentral ) and I wanted to try it right away. I used the Micro SD reader that came with the Cyclo (I noticed it was kinda a tight fit) I deleted all my M3 Simply system stuff off the micro SD card, I kept the games, saves and other files created by the homebrew on the SD card. I put the evo update file onto the SD card, put moonshell on too and turned on my DS. I followed the instructions and it updated to version 1.22. I turned it back on and went to see if moonshell worked. It worked fine, but there were now only 3 files on the SD card 2 folders and the .sav to my tower defense game. AHK! Luckily I keep my stuff backed up every week or so, so thats ok, but there is even a bigger issue...... My 2gb Micro SD card now only has 313.34 mb available when there is nothing on it! AHK! I heard that Kingston Micro SD Cards have a life time warranty, so what do I do to get a new one? Thought Id throw this out there. MY MICRO SD CARD WAS FINE YESTERDAY what caused my micro sd to lose 1.7 gb? why did my new cyclo delete 90% of my files on micro sd card?
