Disco Duro que "desaparece"

Archivado
Tengo un problema con mi PC.

Lleva Maverick instalado y funciona sin probelasm.
Pero tengo un HDD de 1'5Tb que uso como deposito de pelis, series, etc.....y que casi nunca se usa.
El problema es que transcurridos X dias de repente, si me da por mirar su contenido o querer ver alguna perli/serie el HDD ha desaparecido del sistema.

Captura de NAutilus donde se ve que aunque me desplace al HDD esta vacio, (No esta ni montado porque no existe)

Imagen

Si intento vovlerlo a montar desde Term me dice que la unidad no existe:

El unico remedio es reiniciar el PC y entonces todo vuelve a funcionar, pero no entiendo porque me desaprece esa unidad.

Si fuera algo de ahorro de energia seria en todas las unidades , no ???.......en la bios no tengo nada puesto espeical para que se me desconecte el PC, es mas, es un PC que esta 24x7x365 salvo algun que otro reboot por actualizaciones del S.O: o por pruebas que hago, por lo que me molesta bastante tener que reiniciar cada vez solo por "recuperar ese HDD"
Cuando desaparece, si ejecutas en el terminal:

dmesg


¿que aparece?

Ahora mismo el PC lleva en marcha 1d y 6h
La unidad ya ha desaparecido y el dmesg dice un monton de errores que creo son de esa unidad:

En ese dmesg, aparte del error en el disco sdd1 tb aparece un problema en la unidad sdb1 con formato ext4.
Intenta poner los discos en el fstab por UUID a ver si pasa lo mismo.

Siempre los tengo por UUID
Parece que no solo está mal el sistema en ext4 , si no que también el que está en FAT32 está dañado.

¿Puedes poner el fstab?
Haz un test S.M.A.R.T, puede que tu disco duro esté por pasar mejor vida.

No, eso es porque ayer estube metiendo y sacando unas unidades USB FLash y con el cabreo del HDD las metia y sacaba a saco


capitanquartz escribió:Haz un test S.M.A.R.T, puede que tu disco duro esté por pasar mejor vida.


Ya lo he hecho y está perfecto (El HDD es nuevo), de hecho lo compré porque tenia otro y me pasó lo mismo, así que pense que era tema del HDD, y al poner el nuevo me he llevado esta "agradable" sorpresa.
Tambien he probado a cambiar el HDD a otros puertos SATA y lo mismo.

Yo me inclino a que es algo de mi Linux, poer no se que demonios puede ser que se desconecte el HDD y desaparezca por completo del sistema.
