Most PCs have two main types of storage: a small amount of very fast solid-state drive (SSD) storage for the operating system and applications, and a larger, slower hard drive for personal data such as documents, music, movies, and photos. If your computer has only one hard drive, it will store both the operating system and your data on that drive.

The health of a hard drive is important because it can indicate whether the drive is about to fail. If you suspect that your hard drive is failing or if you just want to check its health, there are several ways to do so. This article will show you how to check the health of a hard drive in Windows 10.

What is a Hard Drive?

A hard drive is a device that stores and retrives data on a computer. Hard drives are either internal or external, with the latter being more common in recent years. Internal hard drives are installed inside the computer, while external hard drives are connected to the computer via a USB port. External hard drives are often used to store backups of important data.

Hard Drive Components

A hard drive is a computer’s primary storage device. It holds the operating system, applications, and data. Hard drives come in two basic form factors: 3.5-inch desktop drives and 2.5-inch laptop drives. They also come in two basic connection types: SATA and IDE.

Desktop hard drives are larger in capacity and have higher data transfer rates than laptop drives. Laptop hard drives are smaller in physical size, use less power, and generate less heat than desktop drives.

IDE hard drives are older technology than SATA hard drives. SATA hard drives are faster and more reliable than IDE hard drives.

How to Check the Health of a Hard Drive

Part of effectively managing your computer is knowing how to check the health of your hard drive. While hard drives are generally reliable, they can fail unexpectedly — often without any warning signs. By checking the health of your hard drive regularly, you can catch problems early and avoid losing important data.

There are two main ways to check the health of a hard drive: using your operating system’s tools, or using third-party applications.

Using Your Operating System’s Tools
Most operating systems have tools that can check the health of a hard drive. For example, Windows 10 has a tool called “Check Disk” that can scan your hard drive for errors and repair them if necessary. To use this tool, open the Start menu and type “check disk” into the search box. Then, click on the “Check Disk” shortcut that appears.

If you’re using macOS, you can use the “Disk Utility” application to check your hard drive for errors. To do this, open the “Utilities” folder in your Applications folder (you can use Spotlight to quickly find it). Then, launch the “Disk Utility” application and select your hard drive from the list on the left-hand side. Finally, click on the “First Aid” tab and click on the “Verify Disk” or “Repair Disk” button.

Using Third-Party Applications
In addition to using your operating system’s tools, you can also use third-party applications to check the health of your hard drive. One popular option is Hard Drive Sentinel, which is available for both Windows and macOS. This application will not only check your hard drive for errors but also provide detailed information about its current health status.

To use Hard Drive Sentinel, download and install the application from its website. Then, launch the application and click on your hard drive in the list on the left-hand side. Finally, review the information in the main window to see if there are any problem areas that you need to be aware of.

Tips to Maintain Hard Drive Health

Maintaining the health of your hard drive is important to keeping your computer running smoothly. Here are a few tips to help you keep your hard drive in top condition:

-Defragment your hard drive regularly. This will help keep your files organized and prevent them from becoming fragmented, which can cause slowdowns and other issues.
-Check for errors regularly. Hard drives can develop errors over time, which can lead to data loss or other problems. Running a regular check for errors will help you catch any potential problems early.
-Keep your hard drive clean. Dust and other debris can build up on the surface of your hard drive, causing it to overheat and potentially fail. Keeping your hard drive clean will help prevent this from happening.

Warning Signs of a Failing Hard Drive

Sudden changes in file access times. If files that used to open almost instantly now take noticeably longer, your hard drive is probably failing.

Increasing bad sectors. Bad sectors are areas of your hard drive that can no longer store data. Check your hard drive for bad sectors using a tool like Disk Checkup.

Corrupted data. If you notice corrupted files, especially ones that won’t open or files that have changes in them that you didn’t make, your hard drive is probably failing.

Frequent system crashes or freezes. If your computer crashes or freezes frequently, especially when you’re using a certain program, your hard drive is probably failing.

How to Recover Data from a Failed Hard Drive

There are a few different ways that you can go about recovering data from a failed hard drive. If you have a backup of your data, you can simply restore your files from the backup. However, if you don’t have a backup, you’ll need to use data recovery software to scan the drive and attempt to recover your files.

There are a few things to keep in mind when trying to recover data from a failed hard drive. First, do not try to back up or copy any files from the drive until you’ve taken measures to protect the drive from further damage. Second, be aware that data recovery can be a time-consuming and difficult process, so be patient and don’t expect miracles. Finally, make sure that you have a good backup plan in place so that you don’t have to go through this process again in the future!

Hard Drive Recovery Services

If your computer won’t start up or if you can’t access your data, contact a hard drive recovery specialist as soon as possible. Data recovery services are specialized in retrieving data from failed or damaged storage media.

If you suspect that your hard drive is failing, back up your data immediately. If you wait until the hard drive fails completely, it may be too late to recover your data.

There are several signs that may indicate a pending hard drive failure:

– Hard drives make a clicking noise when they are read. This is caused by the head hitting the disk surface.
– The computer seems to take longer than usual to access files.
– Programs seem to take longer than usual to load.
– Your computer crashes or restarts unexpectedly.
– You receive error messages when trying to access files.


HDD health checking is a process of verifying the structural integrity of a hard disk drive. Hard disk drives are delicate pieces of equipment and can be easily damaged if not handled properly. To check the health of a hard drive, you can use a number of tools, including:

-The manufacturer’s diagnostic tool: Many HDD manufacturers offer their own diagnostic tools to check the health of their drives. These tools are typically only available for their own branded drives and usually need to be downloaded from the manufacturer’s website.

-SMART data: SMART (Self-Monitoring, Analysis and Reporting Technology) is a feature built into most modern HDDs that keeps track of various parameters related to the drive’s health. This data can be accessed using third-party SMART data viewer programs.

-Disk checking utilities: There are also numerous disk checking utilities available that can check the integrity of both HDDs and SSDs. Some popular ones include HD Tune Pro, CrystalDiskInfo, Hard Disk Sentinel, etc.
