Hi all I have this Sandisk Extreme MicroSD 64GB card. I've been copying my Wii-U games on it which worked fine before yesterday. There seemed to be a big problem with it. I made a temp map with the meta files on it from the game Star Fox zero USA and while I was trying to load the game it started up fine but an error came up that the SD card should be removed from the console and that I should restart the console as well. After that not one game worked anymore and every game showed the same error. So I took it out and connected it on on my PC. The card was basically full which had about 7gb or so free. Then I checked the map temp and it was full of weird symbol files and maps which could not be deleted for some reason. And when I checked the space of the "temp" map, it went from orginal 1-10mb to 22 fucking GB? While still having 7GB free and 53GB used. Reformatting didn't work tried exFAT and went back to FAT32 64k. Those files were still there apps, temp, saves (deleted the games before formatting it). I tried a lot of stuff like diskpart utility, chkdsk etc. And then files where found about 12gb or so. Deleted them all and went back to setting it back up with all games. Now all problems came back after copying 5-6 games on it. These sizes varied from 220gb to a total of 7TB.. on a fucking 64GB sd card? Is it still possible to fix this SD Card or is just a bad SD Card (bought it a month ago)?
