Estoy ejecutando El Capitan (10.11.3 beta) en un iMac de 27 "de 2011. Recientemente, mis copias de seguridad de Time Machine (tengo una Time Capsule conectada a la computadora directamente por USB) comenzaron a fallar. Primero, obtuve una Mensaje en el sentido de que la integridad de mi copia de seguridad no se puede garantizar, ofreciéndome realizar una nueva copia de seguridad completa (y perder las antiguas). Aquí están las líneas relevantes en system.log:

Después de eso, borré el archivo de copia de seguridad anterior, desmonté el disco de Time Capsule e intenté crear una nueva copia de seguridad manualmente varias veces. Esto siempre falla después de un tiempo, con un mensaje de error similar a este:

También hay advertencias repetidas similares a las siguientes:
12/29/15 11:21:17.243 PM com.apple.backupd[70000]: Checking for runtime corruption on /dev/disk2s2
Todo esto me parece apuntar a una falla del disco duro. Otro hecho que apoya esta conclusión es que he podido hacer una copia de seguridad en un disco externo USB. Por otro lado, 1) he reiniciado la Time Capsule (que se supone que debe bloquear el disco duro) sin que se detecten errores, y 2) otra computadora mía está realizando una copia de seguridad de forma inalámbrica en esta Time Capsule sin problemas hasta ahora (aunque, A decir verdad, recibo mensajes de "comprobación de daños en el tiempo de ejecución en / dev / disks ..." en el registro de copia de seguridad). Así que mis preguntas son:
1) ¿Cómo puedo probar si mi problema se debe a la corrupción del disco duro? 2) Si la respuesta es "sí", ¿es sencillo reemplazar el disco duro dentro de la Time Capsule? 3) Si cree que el problema puede estar relacionado con el software, ¿cuáles son sus sugerencias para solucionarlo o solucionarlo?
