What is bit-by-bit copy?

Bit-by-bit copy means to copy all areas of a computer hard drive or other storage devices. It replicates all sectors including blank sectors and logically bad sectors, so it is also called sector-by-sector clone. The data stored on the cloned drive is identical to the data on the original drive.

Through bit-by-bit copy, you can:

▪ Upgrade your old hard drive to a new drive without reinstalling the operating system and all your applications.
▪ Get a replica of your computer’s main drive which can be put into use directly in case of hard drive failure.

Since bit-by-bit copy is useful, how can you complete the task?

Why do you need bit copy software?

As Microsoft hasn’t ever included a tool for making an exact copy of a hard drive in Windows, what you need is a reliable bit copy software to achieve the goal of bit-by-bit copy. Cloning disk sector by sector requires the logical sector size of the source and target disks to be same, or the clone process will fail. Therefore, you should choose a bit copy software that is smart enough to skip blank clusters and is capable of cloning between disks in different logical sector sizes. Which bit copy software can meet the demand?

Get the best bit copy software for free

AOMEI Backupper Standard, the best free disk cloning software, can help you with sector-by-sector clone. It offers you two clone modes: Disk Clone and Partition Clone. You may use it to clone either an entire disk or a specific partition.

All Windows PC operating systems like Windows 10/8.1/8/7/Vista/XP are supported. Before you start, you must backup files on the destination drive, because all the data in the destination will be deleted in the cloning process. Then, learn how to do bit copy via Disk Clone below:

Step 1. Download, install and run AOMEI Backupper.

Step 2. Click “Clone” on the left pane and select “Disk Clone”.

Step 3. Select the source disk that you want to clone and click “Next”.

Step 4. Select the destination disk to store the cloned data and click “Next”.

Select Destination Disk

Step 5. Tick “Sector by sector clone”. Confirm the operation and click “Start Clone”.

Start Clone

Step 6. To boot from the cloned system disk, you need to change boot order in BIOS or just replace the source drive with the target one.

Notes:

  • Sector-by-sector clone will copy every sector on the source disk no matter it is used or not, so the destination disk must be equal to or larger than the source disk.

  • If the destination disk is an SSD, you can tick “SSD Alignment” in Step 5 to improve the reading and writing speed of the SSD.

  • To clone OS only to the destination disk or clone system disk between MBR and GPT disks, please upgrade to AOMEI Backupper Professional and use System Clone feature.

Verdict

Bit-by-bit copy is your total solution to protect everything on your hard drive. With the right bit copy software, you will save much time and efforts. In addition to the clone feature, AOMEI Backupper owns the backup, restore and sync functions. You can find a quick workaround to WD Sync not working using AOMEI Backupper. Go for this tool at once!
