Had a 32G SD card in a CF adapter and had no issues with Rockbox. I recently purchased a 128G SD card, restored with Itunes worked fine. Itunes showing the correct memory, even added a couple songs to make sure.
Rockbox installation went fine, or so it appeared, as soon as I tried to add any music to Rockbox it freezes the Mini and I get a Panic Mount 0 error. Should I try a different build?
