Aomei Cloner

AOMEI Cloner is a hard disk and partition cloning application. It creates exact copies of storage units, allowing operating system migration, hardware upgrades, or the creation of full backup copies. The process retains all data, settings, and boot capabilities of the original system.

• System Cloning. This function transfers the Windows operating system, along with its files, installed applications, and boot settings, from a source drive to a destination disk. No reinstallation of the operating system is required. Cloning is performed selectively, copying only the essential system data, which optimizes the space used on the destination drive and speeds up the transfer process. The result is a fully functional operating system capable of booting on the new hardware.
• Disk Cloning. Creates an exact, sector-by-sector replica of an entire storage drive to another. This operation includes all data, partitions, partition tables, and boot records. It is used to transfer the entire contents of a hard drive to a new, larger capacity one, to replace a failing drive, to create a complete disk backup, or to upgrade from an HDD to an SSD. The resulting copy is identical to the original in structure and content.
• Partition Cloning. Allows for the selective copying of a specific partition to another location, which may be another disk or unallocated space. The file structure, folders, attributes, and settings of the selected partition are preserved. This function is used to back up specific data, to reorganize disk space, or to transfer a logical drive with specific information without affecting other system partitions.
• Destination Partition Editing. During the cloning process, this tool enables modifying the partition layout on the destination disk. It is possible to adjust the size of cloned partitions, modify their type, change the assigned drive letter, or merge unallocated space. These modifications are configured before starting the cloning, ensuring that the final result on the destination disk meets the user's space and organization requirements.
• 4K SSD Alignment. During cloning to a solid-state drive, the application ensures that partitions are correctly aligned on 4-kilobyte sector boundaries. Proper alignment is critical for SSD performance, as it reduces unnecessary read/write operations, prolongs the life of the flash memory, and prevents performance degradation. This process is performed automatically and transparently for the user.
• Cloning in WinPE Environment. Executes the cloning operation from a bootable medium based on the Windows Preinstallation Environment. This feature allows cloning disks or partitions without the main operating system needing to be running. It is useful when the system cannot boot due to critical failures, for cloning the system drive, or for working in controlled recovery and system deployment environments.
• Cloning Large Drives to Smaller Ones. Performs cloning from a physically larger capacity disk to a smaller one, provided that the total volume of used data on the source drive does not exceed the capacity of the destination disk. The software analyzes the occupied space and adjusts the process to make it viable. This function is practical for migrating systems from large HDDs to smaller but faster SSDs, or for compact system configurations.
• Multi-Computer Configuration. Facilitates the simultaneous deployment of identical systems on several computers. An administrator can configure a model system with the desired operating system, applications, and settings, create a clone image of its disk, and then replicate that image onto the destination drives of other computers. This ensures a uniform configuration across an entire fleet of computers, reducing manual implementation time.
• Software Testing and Development. Generates identical cloned partitions or disks for use in software testing or development environments. Programmers and IT professionals can work on an exact copy of a production system to experiment, debug, or test new applications and configurations, without risk of affecting or corrupting the main operating system and its original data.
• Replacement of Failing Disks. Provides a method to replace storage drives showing symptoms of imminent failure, such as bad sectors, unusual noises, or overheating. By cloning the problematic disk to a new drive, all data and the operating system are completely transferred, allowing work to continue without interruption and without data loss, before a total failure occurs.
• Backup and Recovery. Creates a complete clone of a disk or partition as a backup strategy. This copy serves as an immediate restore point in case of hardware failure, accidental file deletion, or ransomware attacks. Recovery involves re-cloning the backup image onto the affected drive, restoring the system to its state prior to the incident.
• Support for GPT and MBR Partition Schemes. The application is compatible with the two predominant partition schemes: Master Boot Record (MBR) and GUID Partition Table (GPT). It can clone disks between these schemes or maintain the original scheme, ensuring compatibility with Legacy BIOS and UEFI systems. It also handles cloning between disks with different partition styles when the target hardware allows it.

The development of AOMEI Cloner is carried out by AOMEI Technology, a company specialized in disk management and data recovery software. The program was first released to the market in 2012. AOMEI Cloner is primarily written in the C and C++ programming languages, which gives it efficient performance and direct access to the system's low-level operations for hard disk sector cloning tasks.
