Bueno mi disco ha estado mandando algunos errores al correo:

This email was generated by the smartd daemon running on:

host name: foo

DNS domain: bar

NIS domain: (none)

The following warning/error was logged by the smartd daemon:

Device: /dev/sda, 8 Currently unreadable (pending) sectors

For details see host’s SYSLOG (default: /var/log/syslog).

You can also use the smartctl utility for further investigation.

No additional email messages about this problem will be sent.

Entonces al usar smartctl

No estoy tan seguro de la gravedad del asunto… sin embargo ya estoy respaldando varias cosas :/ por otro lado no estoy seguro de poder conseguir un remplazo para este disco, sin tener que levantar un ticket de servicio y para empezar no imagino que pasa cuando se reporta un equipo con linux…. a final de cuentas no es un disco TAN grande:

=== START OF INFORMATION SECTION ===

Al menos en almacenamiento, que en edad… veamos… 2002? 6 años de funcionar 7×24…. mhh… aunque usando los numeros que da el smart dice que tiene funcionando 2 años…

    Realmente no es ta grave:

    40 51 08 08 36 6f e9 Error: UNC 8 sectors at LBA = 0x096f3608 = 158283272

    El error UNC se refiere a error de escritura, pero no parece ser más que sectores dañados, de hecho esos errores son más comunes de lo que se piensa.
    Podrías probar con: fsck.ext3 -c -y /dev/foo
    con esto debes detectar y asilar los sectores dañados.
    O bien échale un ojo al comando ‘badsectors’
