Forzar la expulsión de un dispositivo

Debido a que mi disco se congela ocasionalmente, tendría que sacar el cable. (consulte la pregunta a continuación para obtener más detalles):

• Seagate Backup Plus 5 TB dejó de responder después de un largo período de uso

He oído que hacerlo dañará (o romperá, en el peor de los casos) el disco, así que me pregunto si hay una forma de expulsar a la fuerza un dispositivo que evite el daño físico. Necesito forzar la expulsión porque la unidad (como otras unidades ordinarias) intentará leer un bloque una y otra vez hasta que se lea correctamente o se agote el tiempo de espera. Cuando se atasque al intentar leer un bloque dañado, el kernel bloqueará el proceso / hilo hasta que haya un resultado. La aplicación en espera de E / S actuará como si estuviera detenida, por lo que ni siquiera usar forzar salida / sigkill no saldrá de la aplicación. Debido a que el tiempo de espera suele ser largo para el HHD de uso doméstico, el componente principal de la GUI del sistema (Finder + Dock) se congelará durante mucho tiempo, lo que evitará el uso normal.

Tenga en cuenta que forzar la expulsión de un dispositivo no es equivalente a forzar el desmontaje de una partición. Forzar la expulsión del disco duro hará que el encabezado de lectura / escritura aterrice en la zona de estacionamiento y la unidad dejará de girar.

Editar: reemplacé mi unidad por una nueva (el mismo modelo, en realidad) y usé ddrescue para copiar todos los datos. Encontré 3 áreas defectuosas que son ~ 1 mb cada una. ddrescue se congeló cuando encuentra estas áreas defectuosas (estoy usando acceso al disco sin formato, es decir, / dev / rdiskX), por lo que no es un problema del sistema. Sin embargo, aún me gustaría saber cómo forzar la expulsión de un dispositivo de almacenamiento masivo cuando está atascado.

• Estoy preocupado por esta unidad. Obtenga una copia de seguridad. Pruebe con un puerto diferente y un cable diferente. Si no es así, considere un nuevo recinto. Si no, una nueva unidad.
• @historystamp El estado de SMART es bueno. Además, esta unidad es nueva y no ‘ t la solté una vez.
• Es ‘ su unidad y tu información. Lo que informa no es ‘ t normal. Algo anda mal. Pruebe con un cable y un puerto diferentes. Pruebe con una computadora diferente si puede. Haga una copia de seguridad de los datos de la unidad. Historial de fallas de la unidad: prosofteng.com/blog/how-long-do-hard-drives-last
