What is the write zeros?

Write zeros to hard drive, also known as zero fill, which is a safe way to clear hard drive effectively by overwriting data with zeros in Windows 10, 8, 7. As known to us, Simply formatting and deleting hard drive can’t clear data completely, and those deleted files can be easily recovered by data recovery software. Compared with formatting a hard drive, the write zeros data sanitization is much more secure and safer.

Once your hard drive is written with zeros, the data on the drive cannot be retrieved by most recovery software. This method will wipe data on your hard drive and prevent soft-based data recovery methods from retrieving data.

2. If you don’t know the file system of your Seagate hard drive. You can double-click computer > right-click your Seagate hard drive > select Properties > file system will be showed on the General tab.

3. Type “y” and press Enter to confirm. And wait for the process to finish, it may take a long time.

4. You can type a name for the drive as volume label, or don’t and then press Enter.

5. Wait for the “Creating file system structures” to show.

6. When the prompt returns, you can repeat the above steps for other partitions on the drive.

7. Type “exit” and press Enter to exit Command Prompt.

Method 2. Write zeros to Seagate hard drive via AOMEI Partition Assistant

As you can see, Command Prompt method is time-consuming and complicated. Besides, you may be not good at running such complicated commands. Fortunately, there is a zero fill Seagate utility-AOMEI Partition Assistant Standard. It provides an easier way to write zeros to hard drive windows 10/8/7.

Tip: You can upgrade to Professional Edition to adopt one of the rest three methods.

  • Fill sectors with random data (Safe, Quick): This method will fill your hard drive with random data. It makes harder for recovery software to lift meaningful information. It is safer than writing zeros.

  • DoD 5220.22-M (Very Safe, Slow): This is a software-based data sanitization to wipe a hard drive. This method will write a random character with 3 passes. It can prevent all software-based recovery tools and most hardware-based tools from recovering data and files. But it takes a little longer time.

  • Gutmann (35 passes, Very Safe, Very Slow): It is also a software-based method to overwrite hard drive. It performs 35 passes. The Gutmann uses a random character for the first and last 4 passes, and the pass 5 through pass 31 will be overwritten by a complex pattern. The method can prevent all software-based recovery tools and most hardware-based recovery tools. It is very safe but takes more time.

Conclude

This is about how to write zeros to Seagate hard drive. Same steps can be applied to clearing a USB stick, or memory card, and other external hard drives. Compared to the method 1, AOMEI Partition Assistant can save much time and efforts. The Professional Edition can provide other more amazing features, such as SSD secure erase wizard, and converting hard drive between MBR and GPT without deleting partitions/losing data.
