Entonces me pregunto:

  1. Tengo un disco duro roto que da como resultado errores de lectura / escritura y del sistema de archivos
  2. INTELIGENTE. los atributos confirman que el disco está roto

¿Por qué mi iMac todavía informa un S.M.A.R.T. verificado? estado?

No sé exactamente qué pasa si algo "verificado" significa, pero puedo confirmar que no significa que el disco está bien. He visto varias unidades que claramente fallaban y que mostraban un estado "verificado", incluyendo una que sonaba inquietantemente como un molinillo de café cuando se estaba ejecutando. - Gordon Davisson
