Welcome to the Rockbox Technical Forums!
I am using an 8gb, sansa fuze and I think I have discovered a diagnostic mode in the latest firmwareI accessed it by ressetting the player (hold power on) then holding the home and play keys while turning on. this gave 4 options diagnostic, northamerican, europe and rest of the world. selecting diagnostic and connecting via usb gave access to the files including upgrade.fin and mtable.sys
