Barang bekas yang saya pesan dari Amazon akhirnya datang juga, SATA 3.5in 160GB seharga 400 yen (sekitar Rp 50.000). Untuk ukuran hard drive, 50rb untuk 160GB adalah harga yang cukup murah saya kira. Namun, apakah kualitasnya masih bagus atau tidak, siapa yang tahu kalau tidak dicek terlebih dahulu. Sekilar dari info yang tertera pada hard drive telihat 26 Januari 2011, ini berarti usia hard drive setidaknya sudah mencapai sekitar hampir 6 tahun. Bagaimana dengan usia penggunaannya? apakah juga mencapai 6 tahun? dan bagaimanakah cara mengetahui usia penggunaan hard drive? jika ingin tahu lebih lanjut, silahkan baca tulisan singkat ini.

Tahukah kalian bahwa computer hard drive saat ini telah dilengkapi dengan SMART (Self-Monitoring, Analysis, and Reporting Technology) yang memperbolehkan kita untuk melihat status "kesehatan" suatu hard drive secara keseluruhan? Banyak sekali informasi yang bisa kita peroleh saat mengakses SMART, dan informasi tersebut dapat pula menjadi sebuah "pertanda" atau "peringatan dini" jika terjadi suatu masalah pada hard drive kita.
Hampir semua Linux dilengkapi dengan paket "smartmontools" yang akan memperbolehkan kita untuk memonitoring hard drive melalui SMART. Sebelum menggunakan paket ini, pastikan paket tersebut sudah ter-install pada komputer anda dengan cara mengetik
---------------------------------
my-ubuntu@my-PC-HP:~$ sudo apt-get install smartmontools
---------------------------------
Salah satu program yang tersedia pada paket ini adalah smartctl. smartctl memiliki indikator "Power_On_Hours" yang secara fungsi mengindikasikan berapa lama suatu hard drive telah digunakan dalam kondisi "on". Bagaimana cara menggunakannya, perhatikan contoh berikut ini.
---------------------------------
my-ubuntu@my-PC-HP:~$ lsblk

Hard drive yang baru saja saya beli berada di "sdb". Sehingga perintah untuk menggunakan SMART untuk menampilkan seluruh info yakni
