Best Sector to Sector Cloning Software [Complete Guide]
Sector-to-sector cloning creates an exact copy of a disk, transferring all data blocks, including hidden and damaged sectors. Discover its benefits, potential drawbacks, essential features in cloning software, and step-by-step instructions for cloning drives easily with AOMEI Cloner.
What Is Sector-to-Sector Clone
Sector-to-sector cloning is a method of copying every sector of a source disk (unused, damaged, or hidden sectors) to a target drive. Unlike file-level cloning, which transfers only active files and operating system components, sector cloning copies the entire disk block by block. It is commonly used in situations such as recovering data from a failed drive, cloning a drive with a complex partition structure, backing up a drive containing encrypted or hidden data, or creating an exact digital copy of a disk.
✅Pros
- Accurately copies the original disk, including boot records and hidden files
- Ideal for data recovery and forensic analysis
- Preserves original partition layout and file system formats
❌Cons
- The copy process is slower because all sectors need to be copied
- Requires larger target disk space than file-level cloning
- If the source drive is damaged, the damaged sectors will be cloned
What to Look For in Sector Cloning Software
Before choosing a sector-to-sector cloning tool, you may consider these features:
- OS compatibility (Windows, Linux, etc.).
- Support for bootable drive cloning.
- SSD-friendly features like 4K alignment.
- Option to choose between intelligent (file-based) and sector-level cloning.
- Clear interface and easy-to-follow wizard.
- Free and paid version availability.

How to Clone Sector-by-Sector using AOMEI Cloner
Step 1. Open AOMEI Cloner after installing. Then, go to Clone > Disk Clone.
Step 2. Select the current disk as the source disk, and click Next.
Step 3. Select another drive as the destination disk, and click Next.
Step 4. You can check the Sector-by-sector clone, which may require that the destination disk size must be equal to or larger than the source disk, and it will need more cloning time and disk space.
Step 5. Check SSD Alignment, and click Start Clone.
Frequently Asked Questions (FAQ)
Q1: Will sector cloning copy the OS and make the disk bootable?
A: Yes, if you use tools like AOMEI Cloner, which also support system disk cloning.
Q2: Can I clone to a smaller SSD?
A: Only if the used space on the original drive is smaller than the SSD, and you use intelligent cloning, not sector-to-sector.
Q3: How can I verify a successful clone?
A: Boot from the target disk and check for file structure integrity. Some tools offer a verification option post-clone.
Conclusion
Sector-to-sector cloning plays an important role in data recovery, digital forensics, and system cloning. Whether you are cloning a failed hard disk, upgrading to an SSD, or backing up an old system, using a reliable tool such as AOMEI Cloner ensures that no data is lost during cloning, making it one of the best choices for users looking for accuracy, reliability, and ease of use.
