Many backup software programs offer a "sector-by-sector clone" feature, which clones all sectors on a hard drive or solid-state drive (SSD), including blank or logically bad sectors. This feature is useful when users want to create an exact copy of their drive, including all data and sectors, even if some sectors are not being used or are damaged. A sector is a subdivision of a track on a disk that stores a fixed amount of user-accessible data. This feature is particularly useful for cloning HDDs or SSDs, allowing users to create a precise duplicate of their drive.
Generally, a sector-A sector-by-sector clone makes no difference to a normal backup. However, if your data is crucial and you want to ensure recovery even if the hard drive has a bad sector, you can opt for this clone mode. This ensures that data from the bad sector can still be recovered.
The sector-Rewriting the disk by sector also has another benefit. It allows you to migrate the Windows OS from an HDD to an SSD without reinstalling, while maintaining the exact same properties on the target disk, such as drive status, size, letter, and volume count. This feature is particularly useful when you want to replicate the exact look of the old disk on a new one.
For a sector-by-sector clone or a normal backup, we recommend Qiling Backup, an all-in-one computer backup and disk cloning solution for home and office users. This tool allows for instant backup and restore, as well as easy cloning, upgrading, and transferring of systems.
The disk clone feature allows users to transfer all data, including system, documents, and media files, to a new or upgraded disk, such as a larger HDD or more efficient SSD, without leaving any blank or logically bad sectors behind.
Learn how to clone a hard drive or solid-state drive (HDD/SSD) sector by sector using Qiling clone software. This process allows you to create an exact duplicate of your existing drive, including all data, operating systems, and applications, onto a new drive.
1. Launch Qiling Backup and choose "Disk/partition Clone" feature.
Step 2. Select the Windows disk or partition that you need to clone and click "Next".
To clone a Windows 10/8/7 partition or disk using Sector by Sector clone under Advanced options, make sure to tick the box to clone every part of the partition or disk without losing any data.
Step 3. Choose the target partition or hard disk that you want to clone to.
Step 4. Preview the disk layout to confirm the settings of the source and destination disk. Click "Proceed" to execute disk clone.
5. Click Proceed to execute disk clone.
After completing the operation, close the Qiling clone software. Then, go to Windows Disk Management to verify that the cloned disk is identical to the source disk.
To access Disk Management on a Windows 7 computer, go to My Computer, click on Manage, and then select Storage, followed by Disk Management.
For Windows 10 computers, go to This PC, then click on Manage, followed by Storage, and finally Disk Management.
Cloning a 1TB disk sector-by-sector can take 20 to 30 hours, requiring patience.
