Zero filling, often termed zeroing, is the systematic process of completely overwriting all data stored on an HDD/SSD with zeros. This systematic write-over entails replacing existing information on the drive with a sequence of zeros. This effectively erases all remnants of previous data and returns the drive to its original pristine state.

Prior to selling, donating, or recycling an SSD, zero filling becomes imperative to safeguard one's privacy and prevent potential misuse of personal information by completely erasing it.

The action to zero fill SSD holds significant implications for data security, privacy maintenance, and drive performance. Explore the full article from EaseUS for a comprehensive understanding of this essential procedure.

What to Do Before Executing Zero Fill SSD

Before initiating the zero-fill process on your SSD, exercising caution is paramount. It is because this action will irreversibly wipe and overwrite all data stored on the drive, rendering it irrecoverable. There won't be any means to retrieve information once the zeroing-out process begins.

Therefore, if you plan to execute zero filling SSD for routine maintenance or simply want to keep the data, it's highly recommended to back up your SSD's data before proceeding. Creating a complete clone of your SSD onto an external hard drive acts as a failsafe, ensuring that your valuable information remains preserved. The following article, with a step-by-step guide, can assist you in creating a duplicate copy of your SSD's contents, providing a secure backup before writing zeros to your SSD.

EaseUS Partition Master has an intuitive interface, making it accessible for users of all levels. Here are the detailed steps to zero filling SSD with EaseUS Partition Master:

We've set two options for you to wipe data. Choose the one you need.

Option 1.  Wipe Partition

  • Right-click the partition you want to erase data from, and choose "Wipe".
  • In the new window, set the time for which you want to wipe your partition, then click "OK".
  • Click the "Execute 1 Task(s)" button in the lower right corner, check the changes, then click "Apply".

Option 2. Wipe Disk

  • Select the HDD/SSD. And right-click to choose "Wipe Disk".
  • Set the number of times to wipe data. (You can set to 10 at most.) Then Click "OK".
  • Click "Execute 1 Task(s)" and then click "Apply".

Way 2. Command Lines of Zero Fill

Executing a zero-fill SSD operation via Command Prompt provides a direct method for wiping an SSD. However, it's important to note that improper operations, like inputting incorrect commands, can result in potentially irreversible consequences.

Here is how to write zero to hard drives using Command Prompt:

Step 1. To start, press the "Win + R" keys to launch Windows's Run function. Here, type cmd and press "Ctrl + Shift + Enter" to open the Command Prompt as an admin.

Step 2. Within the Command Prompt, run the format I: /fs:NTFS /p:1 command.

(The "I" represents the device letter of the targeted hard drive; the "NTFS" is the file system, and "p:1" means executing a single zero-write pass on every sector.)


Step 3. Now, to commence the zero-fill operation, type y and press "Enter." This could be a very long process. You'll need to input a "Volume" Label. Type one that suits your needs, or press "Enter" to skip. If your SSD drive contains multiple partitions, you'll have to follow the same process to write zeros to each partition.


While Command Prompt offers a direct method for zero filling an SSD, it involves complex commands and carries the risk of errors leading to data loss or drive damage. EaseUS Partition Master, on the other hand, provides a user-friendly interface, ensuring a secure and convenient process to erase or wipe SSD without the complexities of command-based operations.

FAQs on Zero Fill SSD

For those seeking clarity on zero filling SSDs, here are answers to common queries related to this topic. These explanations aim to provide a comprehensive understanding of the process.

1. What is the purpose of a zero-fill utility?

A zero-fill utility serves the purpose of completely overwriting all data on a storage drive with zeros. Its primary goal is to ensure that previously stored information becomes irretrievable, essentially wiping the drive clean. This process is often used to prepare a drive for disposal or resale or to enhance performance by erasing data fragments.

2. Is zeroing a hard drive secure?

Yes, zeroing a hard drive or SSD is generally considered a secure method for data erasure. When executed correctly, zero filling ensures that existing data is overwritten with zeros, making it highly challenging, if not impossible, to recover the original information. However, for maximum security, especially in sensitive data disposal scenarios, additional methods or multiple passes of data overwriting may be recommended.

3. What does it mean to zero out a drive?

Zeroing out a drive refers to the process of completely filling the drive with zeros. It can effectively erase all existing data. This process involves overwriting all content in the drive with zeros, ensuring that any remnants of previous data are eliminated. The process will render the previous data unrecoverable.
