Señores hace unos 20 días me instale un servidor voip con un disco sata de 320GB en CentOS 5.3 y hoy revisando las bitácoras del servidor me envía mensajes como este:

SMART error (CurrentPendingSector) detected on host:
SMART error (OfflineUncorrectableSector) detected on host:

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

Device: /dev/sda, 13 Currently unreadable (pending) sectors

For details see host's SYSLOG (default: /var/log/messages).

pero hago unas pruebas con smarctl y me dice que pasa sin errores , esto es extraño.

smartctl -l selftest -i -H /dev/sda
