Why need to clone only used space?
If you are going to upgrade your old disk, you may think of cloning the whole
hard drive onto a new HDD or SSD. However, since there are both used and
unused space on the drive, clone all data on it may be time consuming and waste space,
because of the principle of clone - “the bigger the file is, the more space and time
are needed”. Besides, once you want to clone to smaller drive, the way
will make clone impossible. So we need a better clone solution to reduce the
occupied space and time, and this is to clone only used space which won’t
clone the unused space on drive so as to make a smaller file and reduce the
space and time in a large extent. To do so, a third-party software, AOMEI
Partition Assistant, is a must.
How to clone only used space with AOMEI Partition Assistant?
AOMEI Partition Assistant is a free and powerful software supporting clone
disk only used space. Before it you may think of Windows’ built-in feature, but
it simply can’t do this. Take windows7 as an example, though you can create a system image in Windows 7 with its Backup
and Restore feature, you can’t do clone with it and never to say that clone larger
drive to smaller drive. This situation is same to Windows 8 and Windows 10,
since Windows 8\10 have the same backup and restore feature with Windows 7.
Therefore, AOMEI Partition Assistant with clone only used space feature is
needed, in addition, on this condition that you can clone to smaller drive.
Step 1: Download, install and
launch AOMEI Partition Assistant. Right click the disk or partition you want to
clone(here we choose disk1). Then select “copy disk”.
Step 2:Choose “copy disk quickly” in the pop-up window, which will
only copy the used space of the disk to another disk, then select “Next” to
continue.Tip:“sector-by-sector copy” will clone all data on the disk no matter used or not, and this will take more time and space.
Step 3: In the next page, select a disk as destination disk (here we
select disk 2). When you click “Next”, it will pop up a box that reminds you the
data on the target disk will be deleted.( If there is something you want to keep, I
recommend you use free AOMEI
Backupper to backup first.)
Step 4:Click "Yes" then it will turn to next page which
you can edit disk in three different suggestions. Click "Next"
Step 5:In next page, you could read the note about "how to boot
OS from destination disk" and then click "Finish".
Finally, don’t forget to click "Apply" on the toolbar to implement our
operation on the physical disk. As you see, AOMEI Partition Assistant is a
convenient clone software, also it’s good at solving partition
problems, such as, clone only resize C drive , merge two primary partitionsand so on.
