hard disk

The problem of cooling the computer is not new. The more powerful and faster computers become, the "hotter" they get. Coolers inside computer cases, video card and power supply units are quite common nowadays. However, hard disk has no additional means to cool them. Most hard disk manufacture recommends 35-40°C working temperature for a hard drive. Once it crossed the limit safety of your data and hard disk becomes critical. Computer hard drive is the main storage media for your data.

This article explains how to monitor hard disk temperature and prevent the loss of data under Linux using automated scripts.

netcat utility (nc command) considered as TCP/IP swiss army knife. It reads and writes data across network connections, using TCP or UDP protocol. It is designed to be a reliable “back-end” tool that can be used directly or easily driven by other programs and scripts. At the same time, it is a feature-rich network debugging and exploration tool, since it can create almost any kind of connection you would need and has several interesting built-in capabilities.

This howto explain migrating data between two server hard drives using netcat over a network. It is very easy to copy complete dr

smartctl command controls the Self-Monitoring, Analysis and Reporting Technology (SMART) system built into many ATA-3 and later ATA, IDE and SCSI-3 hard drives. The purpose of SMART is to monitor the reliability of the hard drive and predict drive failures, and to carry out different types of drive self-tests.

smartctl is a command line utility designed to perform SMART tasks such as printing the SMART self-test and error logs, enabling and disabling SMART automatic testing, and initiating device self-tests.

This article demonstrates usage of smartctl tool to test if hard disk is going bad.

This guide shows how to remove a failed hard drive from a Linux RAID1 array (software RAID), and how to add a new hard disk to the RAID1 array without losing data.

This tutorial shows how you can back up and restore hard drives and partitions with Ghost4Linux. Ghost4Linux is a Linux Live-CD that you insert into your computer; it contains hard disk and partition imaging and cloning tools similar to Norton Ghost. The created images are compressed and transferred to an FTP server instead of cloning locally.

The stress test of hardware (hard drive benchmarks) is a simplistic test. There are a number of benchmarking applications software that can be used as hard disk (storage) stress testing. My favorite is Bonnie++ software.

Bonnie++ is a benchmark suite that is aimed at performing a number of simple tests of hard drive and file system performance. Then you can decide which test is important and decide how to compare different systems after running it.
