Step 1. Install and launch AOMEI Partition Assistant,  click the "Wipe" main tab and select "Wipe Hard Disk" option. (You can also right-click the Disk you want to wipe and select the "Wipe Hard Drive" option.)

In this stage, you can also select a wiping method to wipe the selected hard drive according to your requirements and click "OK". (By default, the wiping method is Fill in 0.)

🌟Notes:
  • Fill in 0: Overwrite all sectors with zeros. It is common to wipe a personal hard drive. It is safe and fast.

  • Fill in random information: It overwrites the hard drive with random data. It is more secure than the first one.

  • DoD 5220.22-M: It will overwrite addressable locations on the hard disk with binary 0's, binary 1's, and a random bit pattern from once to seven times. The more times you choose to overwrite, the longer the process will take. Three times to five times are recommended. It is more secure than "zero-filling" and "random data filling" and faster than the Guttman. Thus it is often adopted by companies and organizations.

  • Gutmann: It overwrites a hard drive with 35 passes. It is the safest way here, but it also takes the longest time.

How to low-level format with Hirens Boot CD

First, you need to download the Hirens boot CD. But please note that the downloaded file is an ISO file, and the ISO file cannot be opened directly on the computer. You need to burn the ISO file to bootable CD/USB (because nowadays computers rarely have CD-ROM, so in this article, I will introduce you to how to burn ISO to bootable USB). After the burning, set the bootable USB as the boot program in the BIOS, so that after restarting the computer, you can enter the Hirens boot CD interface and perform the low-level format. I will explain to you in three parts below.

Step 4. Finally, click Start when ready.

Step 57. After that, you've installed HBCD on your USB.

▶ Part 2. The way to set USB as boot drive

In this part, we need to allow the bootable USB to boot the computer. The specific operations are as follows:

Step 1. When the computer shows the startup screen, then press the "Esc" key to enter the BIOS settings. (Some computers may be Delete, F2, or F6)

Step 2. Enter BIOS FEATURES SETUP and set Boot (boot sequence) to USB.

Step 3. After the setting is completed, return to the main BIOS interface, and then select Save and Exit.

Step 4. Insert the bootable USB created in Part 1 into the USB port. After restarting the computer, you will enter the main interface of Hirens Boot CD.

▶ Part 3. Low-level format with Hirens Boot CD

After completing the above steps, we can perform low-level format on Hirens Boot CD.

Step 1. Open "Utilities" on the desktop, find "Security" in "Hard Disk Tool", and double-click "HDD Low Level Format Tool"

Step 2. Choose the hard drive you want to format. and click “Continue”.
