Hi there, long time lurker on here. I have been using the 5.5.1 exploit with an old 2gb micro sd card as a test, which I got working. Received a 64gb Sandisk Ultra today (in the packaging, so I'm pretty sure it's not fake). Formatted the new card to FAT32 with 32k clusters, and added the files from my test card, and all seemed well. However, after adding a couple more games, I get an error before Homebrew Launcher loads (FSgetSourceMount failed). I have not changed the structure from the test card, just added a couple of games, so I'm pretty sure it was set up correctly (it must have been because the new card worked first time, but won't work now). Can anyone elaborate on what this error is, and any thing I can do to fix it...? I have had a quick search on the site, but can't seem to find anything solid (other than that the card is dodgy, but as I say it worked the first time it went in...) I do have some vwii stuff on there, but it didn't seem to make a difference with the test card, or the first time I plugged the sandisk in. Any help would be much appreciated, and sorry if this is a dumb question that's been answered a thousand times.
