Tengo un iPod classic 120GB, tenía el disco duro roto, así que lo cambié por un adaptador genérico de SD/CF a ZIF. Ahora muestra la pantalla "Conectar a iTunes para restaurar" como se esperaba (antes mostraba la X roja y el mensaje "ir a apple.com/support"). Al conectarlo, tanto en Windows como en MacOS, se reconoce correctamente como un iPod que necesita ser restaurado como se esperaba. Sin embargo, después de que se descargue el software del iPod y se inicie el proceso de restauración, éste continúa durante unos minutos pero luego parece congelarse, y el iPod sigue mostrando "No desconectar". En MacOS, al comprobar los registros, veo dos registros relevantes: De iPodUpdater.log:

La luz de actividad del disco en mi adaptador SD/CF -> ZIF también deja de encenderse y el momento coincide con el informe de caída de arriba.

¿Alguien tiene alguna idea sobre cómo solucionar este problema?
