Common Scenarios When You Need to Format a Hard Drive
1. The computer won’t boot
If your computer won’t boot or is stuck on a black screen all the time, you can format your computer’s hard drive. Of course, you can always try other remedies first to fix this problem. However, if all attempts to repair the disk have failed, formatting the computer drive may be the only way to get the computer working again. Maybe that is the only way to make it work.
2. Your computer is running extremely slow
If your computer is running extremely slow, you can speed it up simply by formatting your hard drive. I didn’t see any obvious errors, I just confirmed that my computer was running slow. In this case, there may be a logical problem with your PC rather than a hardware problem. This is how you format your PC’s hard drive and the only way to keep your PC running fast and smoothly.
3. Operating System Update
As you know, outdated operating systems always have many potential risks and are vulnerable to attack. That’s why it’s always a good idea to keep your PC’s Operating System up to date. However, updating your Operating System automatically formats your computer’s hard drive. Therefore, you should back up your drive data before upgrading.
4. The hard disk is filling up
After using your PC for several years, the internal hard disk tends to get cluttered. In this situation, you will need more free space left on your hard drive to store more files.
This means the drive is full. In this case, you can free up more disk space by deleting all unnecessary or useless data.
However, this method cannot clean the hidden temporary files that still take up much space. This allows you to format the drive and thoroughly clean the drive.
5. Registry Errors
If your computer is experiencing many registry errors, you should format your computer drive to correct these errors as soon as possible. The Windows Registry is an essential component of your computer as it contains many configurations and settings for your PC operating system, applications, etc. Therefore, after a registry crash, data tends to get corrupted as well. So, if you encounter such an error, you should back up your data and format the drive immediately.
6. Virus/Malware Attack
If your computer is infected with a virus, you should also format your hard drive. Your computer is prone to crashes in this scenario, and your hard drive is also at risk. You can use antivirus software to get rid of the virus first, but the safest method is to format the drive to prevent further damage.
Regardless of your reason for formatting your hard drive, there are a few things to consider before you begin. First, you need to decide which file system to use. So let’s see which file system to choose.
How to Choose a File System while Formatting a Hard Drive?
Operating Systems use file systems to store data on storage devices. Unfortunately, there is no standard file system that all hard drives use, so the type of file system employed depends on the drive itself and the computer's Operating System.
However, if you’re using macOS, you can use APFS (Apple File System), and if you’re using Windows, you can use NTFS. Both are the latest, fastest, and most secure file systems available for Mac and Windows Operating Systems.
Below we have added a helpful table to help you know more about these file systems you might consider.
|NTFS||This is what Windows uses by default. However, like most file systems, NTFS has limitations outside of Windows. For example, windows platforms can read and write, but macOS and Linux users can only read data from NTFS formatted drives.|
|APFS||APFS Is a default file system for Mac computers. This file system is incredibly quick and efficient and should be your go-to choice unless you require something more specialized.|
|Mac OS Journaled||Protects the integrity of hierarchical file systems using the Mac format (Journaled HFS Plus).|
|Mac OS Extended (Journaled, Encrypted)||It uses Mac format, requires a password, and encrypts the partition.|
|exFAT||exFAT is a popular format for external storage devices such as flash drives and solid-state drives because it is compatible with both Windows and macOS systems and does not impose any limits on the size of files stored on it. Although less widely employed than NTFS, exFAT is a convenient option for plug-and-play operations.|
|HFS+||The Mac operating system uses HFS Plus as its standard file system, the same as Windows utilizes NTFS. Therefore, despite the limitations on Windows machines, Apple users can easily read and write HFS Plus formatted drives.|
|FAT32||FAT32 is an outdated file system that originated with Windows 95 and is compatible with most files. However, it has the limitation of not being able to store anything bigger than 4GB.|
