AOMEI Partition Assistant’s copy with sector by sector function is designed to create backup for a given partition/disk. With the help of this feature, you can manually copy the data and files from one disk or partition to another without data loss.
A sector by sector copy ensures that destination partition/hard disk is exactly the same as source partition/hard disk. It will copy all the sectors no matter it is used or not, even if the sector is blank or it is a logically bad sector. As a result, the target will be equal in size to the disk being copied after the process. This feature is very practical when one wants to make an entire clone for their partition or disk.
Before you do
When you do sector by sector copy for a partition, you must store the copy to an unallocated space. If there is no unallocated space, you could delete or shrink other partitions to create an unallocated space. (Note: sector by sector copy for disk needs no unallocated space.)
The destination partition/disk should be equal or larger than source partition/disk.
Before you perform this operation, Backup or transfer the vital document from destination partition/disk, because they will be overwrote after sector by sector copy.
“Sector by Sector Copy” will copy not only the used sector, but also the unused sector, so it will take longer time than “Copy Disk Quickly” and “Copy Partition Quickly”.
To copy with sector by sector
step1. Open AOMEI Partition Assistant and look at the Wizards on the lefts side of the main window. Choose Disk Copy Wizard or Partition Copy Wizard.
Note: Since disk copy shares the same operating steps with partition copy, we will only demonstrate partition copy through the rest of steps.
step2. Look at the Partition copy wizard, there are two options - Copy Partition Quickly and Sector by Sector Copy. Choose the second option and click “Next” to continue.
step3. As a result of step 2, you will get a new window as below. Choose a source partition and then click “Next”. (as you can see from the following screenshot, I choose H partition as source partition)
step4. Choose a destination partition. You can only choose an unallocated space as the destination Partition. Click “Next” to go to next step.
step5. Put the mouse on F partition, you will see a cross arrow. You can specify the location of F partition by dragging it left or right. Click “Finish” to continue.
step6. Click “Apply” to execute all the operations.
if you copy system partition/disk the operation need to be completed under the PreOS Mode.
Here we have another software that can do Partition Clone or Partition Copy, that is AOMEI Backupper. Moreover, this software also provides Disk Imaging and Partition Imaging functions to help you realize disk/partition backup and disk/partition migration.
