No No, wait, try something atleast. What version of RockBox do u have, and what is the Make of the 32gb microSD? are u sure the microSD isnt a fake one? The reason why i ask for the Version of RockBox is that, they have been patching things, compiling new drivers for microSD cards specially for amsV2. So if ur RB version is pretty old, u might want to upgrade that first. Regards
