How to Permanently Delete Files from SSD: Safe Guide
Have you been looking for methods to permanently erase files from an SSD? If so, you’ve come to the right place! If you are also confused about how a solid-state drive stores and deletes your files, you’ve found your answer! Sending a document to the recycle bin is not a true deletion. In this guide, we will cover the foundational design of SSDs, provide you with a detailed checklist to prepare for wiping your SSD clean, and give step-by-step instructions on how to sanitize your SSD before you sell, donate, or recycle it.
The SSD Deletion Dilemma: Why Your Files Aren’t Actually Gone
Have you ever formatted a storage device and later used data recovery software to recover your sensitive photos, financial records, and personal documents? If you answered yes to this question, you are not alone. Recovering deleted files from a formatted disk is one of the biggest challenges for home users and professionals alike. When you want to learn how to permanently delete files from an SSD, you will quickly discover that simple right-click deletions do not work and you will leave yourself open to identity theft and privacy invasion.
How to Completely Remove Files from SSD
In order to understand how to permanently remove files from SSDs, you first need to consider how these storage devices work on the inside. Unlike traditional HDDs that have spinning magnetic discs in them to read and write data, SSDs use NAND flash memory chips for their storage. When you delete a file from an HDD, the operating system just has to mark that specific readable area of the disc as being available to write new data over it. However, before you can write new data to a flash memory device, you must completely erase the existing data on the flash memory device.
How the SSD is Built
When writing and deleting files from a flash drive, the physical flash memory blocks on the flash drive become worn out over time, meaning they can no longer be written to due to the deterioration of the flash memory. To address this, flash memory manufacturers have created a wear leveling method that attempts to evenly distribute data throughout the entire physical flash memory of the flash drive in an effort to prolong its usefulness.
Thus, when you attempt to overwrite a specific file using traditional wipe software, the controller inside of the flash memory drive will send the command to a different physical sector from where the data was located. Therefore, when the data is still on the flash drive, the data will not be overwritten, and that is why you must use a special command such as the Secure Erase command in order for you to completely remove all of the data from the flash memory device.
Quick Checklist Before DIY Methods
Before attempting to remove files from your hard drive, take a moment to review this important checklist first. This is a very important thing to do since if you do not have an instant access point to your data, you will lose it eventually.
Back Up Your Data
Make sure that if you need to, you have saved all documents to an external drive or backed them up onto cloud storage, because if you perform a secure erase there’s no way to retrieve deleted files.
Test Drive
If your drive has developed bad sectors, running intensive commands on the drive may cause it to fail completely. You will want to check for any drive health issues prior to putting the hardware under any significant stress.
Prepare Your Tools
You need to be sure that you have either downloaded the associated manufacturers software to execute the commands or you have administrative permission to your operating system to execute low-level formatting commands.
Remove Unused Drives
To be safe, be sure to physically disconnect from your computer other external drives such as USB thumb drives, backup drives and any other external drives you do not want to be inadvertently wiped.
Connect to Power Supply (If using Laptop)
To reduce the risk of a power failure due to your laptop becoming disconnected from the mains during low-level formatting you must plug the laptop into a wall socket for continued power, or you risk a complete failure of your drive rendering it unusable.
Read the Manuals
Glance through your motherboard or laptop manual to see if a secure erase utility is already built into your system’s BIOS/UEFI environment.
Precautions Before Wiping Data
Never rely on standard formatting. Performing a “Quick Format” in Windows only deletes the file table, not the data itself. Always double-check drive letters and partitions. Typing the wrong digit in a command prompt can instantly wipe your main operating system instead of the intended target drive.
Step-by-Step Manual Methods
Method 1: Using Windows DiskPart
For advanced Windows users, the built-in DiskPart tool offers a straightforward, albeit intimidating, way to permanently delete files securely. Here is how to navigate it:
- Press the Windows Key, type “cmd”, right-click on Command Prompt, and select “Run as administrator”.
- Type
diskpartand press Enter. - Type
list diskand press Enter. Carefully identify the disk number of your solid-state drive by looking at the storage capacity. - Type
select disk X(replace X with your exact disk number) and hit Enter. - Finally, type
clean alland hit Enter. This forces the system to write zeros to every single sector. Note: This process will take a significant amount of time depending on the capacity.
Method 2: Manufacturer Specific Software
Most major storage manufacturers provide free management software tailored to their hardware. This is often the safest manual route to completely delete files from SSD, as it communicates directly with the drive’s controller to execute an ATA Secure Erase.
- Identify the brand of your drive (e.g., Samsung, Crucial, Western Digital).
- Download their official dashboard or magician software from the official website.
- Navigate to the “Tools” or “Security” tab within the application.
- Select the “Secure Erase” feature. The software may prompt you to create a bootable USB drive to perform the action outside of the Windows environment.
- If you are working with newer memory architectures, you might also want to learn the specific steps to safely wipe NVMe drive storage, as they interface differently via the PCIe bus.
Method 3: Motherboard BIOS/UEFI Utility
Many modern motherboards have an erasure utility baked directly into the firmware.
- Restart your computer and rapidly press the setup key (usually F2, F12, DEL, or ESC).
- Navigate to the “Advanced” or “Tools” section in the BIOS menu.
- Look for a utility named “Secure Erase” or “NVMe Sanitization”.
- Select the target drive and confirm the operation. This method is incredibly fast and bypasses the operating system entirely.
The Drawbacks of Erasing SSDs through Manual Methods
While free, there are many major drawbacks to using your own methods and no third-party software, in order to do a complete (or almost complete) erasure of your files.
- No Verification
When you use command line tools or features in the BIOS, there are no logs or certificates produced to confirm that 100% of the data was actually destroyed. You will have to have faith that it worked.
- Risk of Damage to Drive
Executing a clean all command requires an immense amount of writing to the storage device which causes the device to wear out and fail at a much faster rate than if the device had never been written to before.
- Command Line Complexities
Using command line tools to erase data must be to the letter in order to not lose data. If there is even a single typo in the DiskPart command, you run the risk of destroying your operating system and/or user files, on an entirely different drive or partition.
- Failure to Reach Hidden Recovery Partitions
Manual erasure methods often result in some portion(s) of the previous use of the SSD remaining intact.
- Time Taking
When you factor in the hours spent creating bootable USB drives or trying to monitor your progress through legacy BIOS menus, waiting for zero fill commands on multi-terabyte drives will eat up a significant portion of your day.

Frequently Asked Questions
Q: Does a factory reset erase data completely from an SSD?
No. A standard operating system factory reset only removes the directory pointers to your files. The actual raw data remains on the physical flash chips and can often be easily recovered with free internet software.
Q: Can I just physically destroy my SSD instead?
Yes, physical destruction (like shredding or drilling through the memory chips) is a 100% guaranteed method to completely delete files from SSD, but obviously, this ruins the hardware so it cannot be reused, sold, or donated.
Conclusions
In today’s modern era it’s essential that you learn how to permanently delete documents from a Solid State Drive (SSD). Due to the way solid state drives operate and function they may have different methods for deleting data than traditional mechanical hard drives (HDD). Physically removing data is often an irreversible process and it is important that you are aware of how to delete your data correctly if you want to maintain your privacy and to ensure that your data can’t be recovered later.
Whether you use the built-in utilities provided by the motherboard or rely upon the manufacturer’s utility or some sort of third-party application will depend upon what your requirements for deleting your data are. Remember, you should verify that your data is backed up, check that your drive has not been compromised, and always work with someone who has experience in sanitizing drives prior to deleting any sensitive information. Make sure to always have proper protection before proceeding along the path to sanitizing the drive.
