How to Clone an OS Disk, Partition, or Disk?

The Clone feature in iBoysoft DiskGeeker works to make an one-to-one copy of a OS disk, non-system partition, or disk to another.

Warning: Cloning will erase all contents on the destination disk, so back up your essential files before starting cloning. Or else, you'll face irrecoverable data loss.

Clone an OS disk

This is to help you make a bootable system copy on a hard drive for system migration, storage device upgrade, or system file backup.

Step 1: Click "Clone OS disk" from the Clone module to directly open Clone OS disk window. Or, you can click "Clone" > "Clone OS disk."

Clone module

Step 2: Check the source disk from the Source OS disk section.

In the Source OS disk section, the software will automatically list the system partition it found and also show the system version and the partition condition.

confirm source disk

You can click "View disk" to check the distribution of the disk where the system partition resides, so to verify if the system partition is selected correctly. Here, the selected system partition will be marked green.

view disk

Note: If the BOOT and SYSTEM partitions in your system are separated (that are the C drive and the EFI system partition in Disk Management), even if the Source OS disk section only shows the BOOT partition, both the BOOT and SYSTEM partitions will be cloned to the target disk to guarantee the cloned system partition bootable.

Step 3: Choose the destination disk. Hover on the "Select a destination disk" button and you'll see a list of available target disks.

The storage capacity of the destination disk must be larger than the source disk's. Or else, the one-to-one disk clone will fail. For example, the source disk is 200GB, so the destination disk must be larger than 200 GB.

Step 4: Confirm if you have chosen the right target disk, have backed up data from the destination disk, and then click "Start" > "Confirm."

confirm target disk

Step 5: Wait for the cloning process to complete.

When cloning starts, the disk distribution map of the target disk will be displayed as a visual progress bar.

os disk clone process

Step 6: Finish.

finish os disk clone


• You can cancel the system partition cloning task at any time during the process.

• You can't clone the system partition as a BitLocker-encrypted partition as it will make the bootable system copy unbootable.

• You can conduct incremental system cloning (or called incremental backup) but not in the OS disk clone module. Switch to the Clone partition module after finishing a system partition clone, and then choose your system partition as the source partition and the cloned system partition on the destination disk as the target partition.

Clone a partition

Partition clone helps you create a copy of any partition (including a BitLocker-encrypted partition) so as to make an exact backup.

Only allocated partitions with over 500 MB in size can be cloned.

Step 1: Select "Clone partition" from the Clone module to enter the Clone partition window. Or, you can click "Clone" > "Clone partition."

Clone module

Step 2: Click "Source partition" to choose the partition you want to clone.

choose source partition

You are allowed to choose a BitLocker-encrypted partition as the source partition.

After selecting the source partition, you'll see the basic info of the partition, such as partition label, drive letter, total capacity, available space, etc. You can click "View disk" to view the disk condition where the selected partition resides. The selected partition will be marked green here.

source partition info

If you want to change the source partition, click the "Reselect" button for a change.

Step 3: Move your cursor to "Target partition" and select your destination partition from the list.

The Target partition button is available only after you choose the source partition.

Step 4: Set up your cloning preferences.

setup partition clone preferences

Partition clone in iBoysoft DiskGeeker contains two modes - full clone and incremental clone.

By default, you are in full clone mode after choosing the target partition. Only if you've completed a full clone on the same two partitions, you'll see the "Switch to Incremental clone mode" button and click it to switch to incremental clone.

change to incremental clone

Full clone mode: Copy all data on the source partition to the target partition one by one where sector-level clone exactly clones all existing data on the source partition and also all available space to the target partition. Sector-level clone mode considers all space of the source partition, including the available space, as valid data storage space.

Incremental clone mode: Compare the data on the source partition and the target partition first, and then only sync the inconsistent parts of the data between the source partition and the target partition. That saves a lot of time for disk cloning. Incremental clone only applies to clone an NTFS partition.

Note: If you need to encrypt the target partition for data protection and avoid ransomware attacks, check the "Clone to a BitLocker encrypted partition" button and enter your password. You can clone a source partition as a BitLocker partition with full clone mode but can't do that with the incremental clone mode.

clone as encrypted partition

Step 5: Click "Start."

The full clone usually takes a relatively long time, especially if you select "Sector-level clone."

partition sectore-level clone

During the incremental cloning process, the target partition will be locked by default in case data on it is tampered with. When the target partition can't be locked in some cases, you'll be asked whether to force-lock it.

Step 6: Confirm to start clone.

confirm partition clone

Step 7: Wait for the cloning to end.

partition clone finish

Clone a whole disk:

Disk clone makes an exact copy of all partition information and data on each partition on the target disk to a destination disk with the same sectors.

Step 1: Click "Clone disk" from the Clone module to open the Clone disk window. Or, you can click "Clone" > "Clone disk."

Clone module

Step 2: Click "Source disk" to choose the source disk from the list.

select source disk

The selected source disk will be listed in the Source disk section. You can see all its partitions and their basic info here. If you want to change the source disk, click the Reselect button for a change.

Note: You'll see the confirmation message below if you choose a hard drive containing Windows OS. As it describes, if you need to clone an OS disk as a bootable system disk, click Yes to switch to the OS disk clone mode. If not, click No to continue.

switch to OS disk clone confirmation popup

Step 3: Hover your cursor on "Target disk" to select the destination disk.

The storage capacity of the target disk must be larger than the source disk's.

Step 4: Confirm the target disk and your settings.

If you want to make a 1:1 copy of the source disk rather than only copy the files, check "Sector-level clone." A sector-level clone will take longer time than a normal full clone.

Step 5: Click "Start" > "Confirm" to start a disk clone.

How to Analyze Space of a Partition or Folder and Clean Files?

Space Analyzer can analyze the used space in a system partition, user folder, or any other specified folder. It is designed to quickly find the large files and folders in the system partition or target folder so as to clean up a PC or external hard disk and release more free space.

Step 1: Select a space analysis feature you want from the Space analyzer module.

Click "OS partition analysis," "User folder analysis," or "Specific folder analysis" from the Space analyzer module. Or, click "Space analyzer" and then select your desired analysis feature.

choose Space analyzer

OS partition analysis: Analyze the storage usage of the system partition.

User folder analysis: Analyze the storage usage of the current user folder.

Specific folder analysis: Analyze the storage usage of any folder you choose.

Step 2: iBoysoft DiskGeeker for Windows will automatically analyze the files in the selected location.

It will take a relatively long period to scan the files in OS partition and user folder as it stores a huge amount of your data.

space analysis process

Step 3: Check the scanned results by clicking the listed folders.

The scanned results can be displayed in two modes: Visual mode and Non-visual mode.

In visual mode, the left and right views are the same level directories, and the right view is a visual presentation of the files in the left view. Turn off the Visual mode button in the upper right corner, you can only see the text table of contents.

visual mode

In non-visual mode, the software displays the preceding and following levels of directories of the current path (a total of three levels of directories). When there are less than three levels of directory structure, it displays all path structures.

non-visual mode

Step 4: Select your unwanted files and drag and drop them to the Trash Bin at the bottom of the window (a blue circle).

This is to collect all the files you prepare to delete, and the Trash Bin will show the total size of these files.

Note: System partition is special as you consistently write data onto it since your PC boots up. Thus, the way to test the speed of a system partition is through reading and writing files through the file system, and the available space on the system partition should be over 10 GB. During the speed test, 5 GB of data will be written to the system partition and once the test is completed, it will be immediately deleted.

Step 3: Choose a speed test mode you want.

There are four speed-test modes for partitions and entire disks.

disk speed test modes

Read-only: Read data on the test area of a partition or disk from the beginning to the end. It takes little on the disk's seek time.

Read-write: Read and write data on a test area of a partition or disk from start to end. It spends little on the disk's seek time.

Random read-only: Randomly read data on a partition or entire disk. It takes a relatively long time on the disk's seek time.

Random read-write: Randomly read and write data on a partition or entire disk. It takes a relatively long on the hard drive's seek time.

1. Only read-write and random read-write modes are available for a system partition.
2. Only read-only and random read-only modes are available for BitLocker-encrypted partitions.

Step 4: Wait for the speed test to end.
