Pada Sistem Operasi Linux terdapat tools pengecekan hardisk yang cukup bermanfaat yaitu smartctl, Anda bisa menemukan berbagai informasi penting dengan menggunakan tools ini.
Untuk Centos/Redhat install paketnya dengan cara :
# yum install smartmontools
Melihat Informasi Hardisk
# smartctl -i /dev/sdb
Mengaktifkan Smart Monitoring pada Hardisk sdb anda
# smartctl -s on -d ata /dev/sdb
