Pada tutorial kali ini kita akan melihat detil spesifikasi sebuah harddisk yang terpasang di komputer Linux. Tutorial ini bisa dipakai pada komputer maupun server yang menggunakan OS Linux.
Untuk kebutuhan tutorial kali ini kita akan menggunakan perintah hdparm. Biasanya sudah terpasang dihampir semua distro Linux.
Cara menggunakannya seperti berikut:
sudo hdparm -I /dev/sda
dengan /dev/sda adalah simbol harddisk di komputer. (biasanya sda untuk harddisk utama, dilanjut dengan sdb, sdc, dan seterusnya).
contoh hasilnya:
/dev/sda:
