What does it mean to reformat your computer?
Reformatting a computer means erasing all the data on the hard drive(s) and then reinstalling the operating system for a fresh start (https://www.wikihow.com/Format-a-Computer). This process is also referred to as formatting.
Formatting wipes a hard drive clean of its data, including the operating system, installed programs, personal files, etc (https://smallbusiness.chron.com/reformat-pc-56157.html). It allows you to do a clean install of the operating system.
There are two main types of formatting – quick format and full format:
- Quick format – This just writes a new file system over the existing one. It is faster but does not fully erase all data.
- Full format – This overwrites the entire hard drive to completely wipe all data. It takes longer but is more secure.
The basic process of reformatting involves backing up important data, booting from the operating system installer, choosing the disk to format, selecting quick or full format, and installing the OS. This prepares the hard drive to be used by the fresh operating system install.
Reasons people reformat their computer
There are several common reasons why people choose to reformat their computer:
To start over with a clean slate – Reformatting wipes your computer completely clean, deleting all files, programs, settings, etc. This allows you to start fresh with a blank slate if your computer has accumulated a lot of clutter or programs over time that are slowing it down.
To resolve performance issues – If your computer is running very slow, freezing, crashing frequently, etc., reformatting can help resolve these performance problems by erasing any corrupted files or conflicts between programs. The fresh install often improves speed and stability.
After getting malware/virus – If your computer gets infected with a virus or malware, reformatting is often the most thorough way to disinfect and remove all traces of the malicious software. It essentially resets everything and gives you confidence there are no lingering threats left behind.

Pros of reformatting
One of the main benefits of reformatting your computer is that it removes all files and custom settings, restoring your machine to a clean, fresh state. This process can help fix software issues and crashes that may be caused by corrupt files or registry errors. According to one source, “Formatting the system removes all the files and errors and restores the computer to a blank state.” [1]
Reformatting can also significantly improve your system’s overall performance. Over time, computers tend to slow down as the hard drive fills up with programs, files and fragmented data. Wiping the drive clean eliminates this clutter and allows your system to operate faster. As one article explains, formatting “will clean your computer’s hard drive and wipe all the cluttering files, programs, useless registries.” [2]
By reformatting your computer, you’re ensuring that the operating system and applications are installed on a clean slate. This can resolve a wide range of software-related problems, crashes and bugs. According to experts, formatting “makes it a fresh drive to install a new or existing operating system and software.” [3]
Cons of reformatting
The main drawback of reformatting your computer is that you will lose all personal files and data stored on the hard drive. This includes documents, photos, music, applications, and any other files you have saved. Reformatting essentially wipes the hard drive clean, so everything will be erased unless you have backed up your data elsewhere.
According to Super User, reformatting can cause “Data loss: As mentioned, formatting the hard drive erases all data stored on it, including documents, photos, music, and other important files.” Backing up vital data is crucial before reformatting to avoid permanent data loss.
Reformatting your computer is also a very time-consuming process. You will need to reinstall the operating system, drivers, applications, and customize your settings again. This can take many hours or even days depending on how many programs and files you need to set up again.
According to Quora, you will have to “Reinstall all your software programs. This can be time-consuming.” Taking the time to reinstall everything on your system is a key downside to keep in mind.
Overall, the potential for massive data loss, time investment, and effort of reinstalling the operating system and programs make reformatting inconvenient for many users. It’s best to exhaust other options before resorting to a complete reformat.
How to backup your data
Backing up your data before reformatting your computer is crucial to avoid permanent data loss. Here are some of the main ways to backup your data:
Copying files to an external drive: You can manually copy important files like documents, photos, videos, etc. to an external hard drive or USB flash drive. Make sure the drive has enough storage capacity to hold all the data you want to backup [1].
Using cloud storage: Services like Google Drive, Dropbox, OneDrive, etc. allow you to backup files to the cloud. You can either manually upload files or use the desktop app to automatically sync folders [2].
Imaging the hard drive: Software like AOMEI Backupper can create a full system image, saving an exact copy of your hard drive including the operating system, settings, programs, and files [1]. This allows restoring your exact PC state if needed.
Steps to reformat your computer
Before reformatting your computer, it’s crucial to backup your files and data. As this source mentions, reformatting will erase everything on your hard drive. Back up important documents, photos, music and other files you want to keep either on an external hard drive, cloud storage or DVDs.
The next step is booting your computer from the Windows installation media. You’ll need a Windows installation DVD or USB drive. Boot your computer into the setup wizard, following the on-screen instructions to boot from the installation media instead of the hard drive. As outlined in this guide, you may need to adjust your BIOS settings to enable booting from the installation media.
Once you’ve booted into the setup wizard, you can choose the option to format your hard drive. This will erase all existing partitions and data. You’ll then be able to install Windows fresh onto a clean drive formatted to your preferences.
Choosing quick vs full format
When reformatting your computer, you’ll need to decide between a quick format or a full format. The main difference between these two options is that a quick format only cleans the file table, while a full format scans the entire disk.
A quick format is faster since it just resets the file table and marks all existing files as deleted. This takes seconds to complete. A full format is more thorough because it analyzes the disk sector by sector to find and fix errors. This process can take hours depending on the size of your drive.
According to EaseUS, quick formats are sufficient if you intend to reuse the drive yourself. However, full formats are recommended if you plan on selling, gifting or disposing of the drive since it wipes all data completely.
In most cases, a quick format will be adequate when simply reinstalling Windows or resetting your computer. But if you want to ensure everything is wiped and avoid any chance of data recovery, a full format is more secure.
When should you reformat?
There are a few key instances when it makes sense to reformat your computer:
If your computer is running slow – Reformatting can help speed up a computer that has become sluggish over time from too many programs, files and a cluttered registry. Doing a clean install of your operating system can clear out all the clutter and restore performance.
After a malware infection – If your computer has been infected by a virus, trojan or other malware, reformatting is often the best way to ensure all traces of the malware are removed. The reformat will wipe your drive and allow you to start fresh with a clean OS install.
When giving away or selling your computer – Before passing your computer on to someone else, either by selling it or giving it away, you’ll want to reformat to erase all your personal data and files. This protects your privacy and gives the new owner a fresh start.
Overall, reformatting is recommended when your computer is having significant performance issues, has been compromised by malware, or is being given to a new owner. Doing a full reformat and clean OS installation can restore speed, remove infections, and protect your personal data.
Alternatives to consider first
Before deciding to reformat your computer, there are some alternative options that are less disruptive and can help improve performance without erasing everything.
One option is to run the built-in Disk Cleanup utility in Windows. This cleans up unnecessary files and frees up space on your hard drive (Source: https://www.techpowerup.com/forums/threads/better-alternative-than-reformatting-my-pc.60187/). You can also run the Disk Defragmenter to optimize the layout of files stored on your hard disk.
Another alternative is to reinstall your operating system without formatting the hard drive. This will refresh your OS while preserving your personal files and programs. Just be sure to back up important data first (Source: https://tweaks.com/windows/67042/two-alternatives-to-a-windows-reinstall/).
You can also restore your system to an earlier state using System Restore points in Windows. This can reverse changes that led to problems without losing data (Source: https://www.makeuseof.com/tag/clean-computer-original-state-reinstalling-windows/).
Summary
Reformatting wipes a computer clean by erasing all files, programs, and settings. The pros are that it removes unwanted files and has the potential to improve performance. However, the cons are losing data and the time it takes to reformat and reinstall programs. If you do reformat, make sure to backup any important files first, and be prepared to reinstall your operating system, apps, and settings afterward.
Overall, reformatting can be a good option if your computer is having significant performance issues or you want to start fresh. But it shouldn’t be necessary very often if you regularly maintain your computer. Consider trying other troubleshooting steps first before taking the drastic step of reformatting your entire system. And never reformat without backing up your files, to avoid losing valuable documents and data.
