How to Maintain a Healthy Hard Drive
All computers have a hard drive installed in them, which is used to store files for the operating system, software programs, and a user's data. A computer cannot come into play without a hard drive whirling. To correctly cooperate with a hard drive, or an external one, you must possess some necessary know-how skills for keeping a storage device healthy, and in turn, prolonging its life.
Thereby, we think these three routine jobs should be carefully implanted in daily use.
1. Everyday data backup
You can back up a whole hard drive data, a certain partition, user archives or even an operating system. This is the most guaranteed way of attempting all chances of hard drive recovery without worrying about data loss (e.g. Some fixes within this page are meant to erase data, making it unrecoverable). There are native backup tools for Windows, namely Backup and Restore for Windows 7, 8.1 and 10, and File History for Windows 8. But modern people tend to prefer third-party free backup software, they choose over more intuitive, user-friendly, versatile and more features involved backup plans to replace such a dull and flat Windows utility. EaseUS Todo Backup Free perfectly meets an everyday backup of a hard drive, partition, files, folders, etc.
2. Periodic disk cleanup and system optimization
Remove junk files, useless but extremely large files or system/browser cache files that occupy precious disk space, to avoid the risk of the computer becoming slow. Why not use simple disk cleanup to boost hard drive performance?
In addition, the longer you use the machine in a settled location, the more dust and debris in the air will accumulate and cause the hard drive to overheat and malfunction. You may use a small piece of cotton rag and a dip of alcohol to clean it by yourself, and a cotton bud is also a good choice for the inside areas.
3. Take advantage of Power Save and Sleep Modes
Though there are large brands that announced a longer lifespan, you need to accept the truth that the less time your drive is running, the longer it will last over the lifetime.
Therefore, turn off the hard drive after some time of complete inactivity. Likewise, when your computer is idle, try to utilize the Power Save and Sleep Modes, to keep it from performing certain general maintenance tasks such as defragmentation, checking Windows updates, third-party activities, etc.
