How to clean your hard drive?

Recently, as part of research to help a visitor who had a problem retrieving files from his USB drive, I was led to do some research on the web on hard drive problems …

Because of their relative fragility and their crucial content (our personal data and so precious files), many of us are confronted at one time or another with physical or software problems related to our hard drive.
Whether it is a classic hard drive (called HDD), SSD hard drive, or removable storage such as a USB key or an SD card.

A good way to preserve it? Regularly perform a deep cleaning of your hard drive!

Why clean your hard drive?

Hard disks are one of the most stressed parts of a computer: they are accessed, written to and data constantly read.

The more full a hard drive is, the more likely it is to slow down your operating system. In particular because of its fragmentation but also because a lot of useless system files linked to Windows are stored there (trash, old error reports, software installation files, etc…).
It is also possible that you keep large files (such as video files for example) that you do not necessarily want to keep.

I also advise you to clean your disk before making a backup of Windows 10 (or other OS), this avoids saving unnecessary files and having a lighter and cleaner backup!

Clean a hard drive with the Windows utility

Windows has a convenient and easy-to-use utility that allows you to wipe a partition on its hard drive such as the system partition where your version of Windows is installed 

The following procedure and the Windows screenshots were taken with Windows 10 but the procedure is valid with other versions of the Microsoft operating system ( Windows 8.1, Windows 8, Windows 7, Windows Vista, Windows XP, etc … ).

Here’s how to clean your system partition with the tool built into Windows:

  1. Open a Windows file explorer, right-click on the partition you want to clean up (the C system partition for example) and click Properties .
  2. In the Properties of: Local Disk (C 🙂 window , click the Disk Cleanup button to start the partition scan
  3. Wait while Windows analyzes what can be cleaned on your partition.

Note: in step 4, the Clean up system files button (which requires administrator rights ). If you have the necessary rights, click this button. Windows will re-scan your partition for system files that can be deleted without concern, especially Windows Update update files which can take up a lot of disk space. You will normally have one more line in the list of files to delete, Windows Update Cleanup. Select the files to clean and then click OK to start the cleanup process.

Cleaning a hard drive with EaseUS Partition Master

During my research, I came across EaseUS Partition Master software, published by EaseUS company which also publishes EaseUS Todo Backup backup software, and EaseUS Data Recovery Wizard data recovery software, which has some cool cleaning features. hard drive.
