Secure Data Replication: Bit-for-Bit Copying for Hard Drives

Performing a bit-for-bit copy of a hard drive can be beneficial in different situations. Examples include upgrading to a larger drive, ensuring data preservation, or performing forensic analysis. A bit-for-bit copy replicates every data byte from the source drive onto a target drive.

Are you in need of the exact steps for doing this? This guide will explore the different cloning software to help you make a bit-for-bit hard drive copy.

What Is Bit-By-Bit Copy?

The term "bit-by-bit copy" refers to copying all sections of a computer hard drive or other storage device. Because it replicates all sectors, including blank and logically bad sectors, it is also known as a sector-by-sector clone. As a result, the destination hard drive is similar to the source hard disk and retains the same features, such as drive status, drive size, drive letter, number of volumes, and so on.

You can do the following with a bit-by-bit copy:

  • Change your old hard disk to a new one without reinstalling the OS and all your applications.
  • Obtain a duplicate of your computer's main drive that can be used straight in case of a hard drive failure.

This bit-for-bit hard drive copy method will be quite important and handy when you need to clone a hard drive with faulty sectors or when you want an exact look of the old disk on a new disk. Following that, we will demonstrate how to clone a hard drive bit by bit.

Best Software To Make a Bit-for-Bit Copy of Hard Drive

Using reliable software is the easiest and most efficient approach when making a bit-for-bit copy of a hard drive. There are several reputable software options available that offer robust features for creating accurate disk images. Here are some of the best.

AOMEI Partition Assistant

Another hard disk cloning utility is the AOMEI Partition Assistant Standard. It is a free yet sophisticated partition manager. Its "Disk Clone Wizard" and "Partition Clone Wizard" both have the "Sector by Sector Clone" method for cloning a hard drive or partition bit by bit. There are also "Clone Disk Quickly" and "Clone Partition Quickly" options, which allow you to clone used sectors to a target place or a larger drive to a smaller drive.

Adhere to the following instructions to make a bit-for-bit copy of the hard drive using AOMEI Backupper Standard.

  • Step 1: Open AOMEI Partition Assistant. In the right menu, select Clone Disk.
select clone disk
  • Step 2: In the next window, select Sector-by-Sector Clone and press the Next button.
select sector-by-sector clone
  • Step 3: Select the destination disk and press the Next button.
select the destination disk

Note: Boot the computer from the cloned disk. Ignore that if you're duplicating a data disk.

boot the computer
  • Step 4: Click Apply and Proceed in the main interface to begin the bit-for-bit disk clone.

Note: The bits will then be copied to the destination hard drive. The Standard version only supports MBR disk to MBR disk cloning for cloning system hard drives bit by bit. Upgrade to the Professional edition if you intend to replicate an MBR-based system disk to GPT, GPT to MBR, or GPT to GPT.


When doing bit copy for a hard disk, the correct software will save you much time and work. Wondershare UBackit also has backup, restore, and sync operations in addition to the clone capability. Get this tool right away!
