Need to copy all data from one hard drive to another
The two main motivations to transfer/copy data from one disk to another are concluded as follows:
☞ Transfer all data from traditional hard disk drive with Windows installed to solid-state drive or larger hard drive; thus you can upgrade system hard drive without reinstalling Windows.
☞ Clone all data from internal hard drive to external hard drive for duplication; compared with backup, it allows you to access data without restoring, if the system crashes or something else happens.
For moving/cloning files from one hard drive to another, you might consider using copy & paste function. However, this way can be time-consuming when there are lots of files and folders on your hard drive. And some applications & OS won’t work normally on the new hard drive. Therefore, you can employ hard drive cloning software to copy the whole hard drive to another.
Here AOMEI Partition Assistant Professional will be my first choice. It can clone all files, including boot.ini from one disk to another. After cloning system hard drive to another drive, you can boot from the new drive in success.
It can clone only used spaces on the source hard drive, thus you can copy all data from one hard drive to a smaller one if the size of the target one is not less than the size of used space.
What’s more, it is able to copy only OS drive (data partitions not included) from one disk to another.
Step to clone whole hard drive to another
What you ought to realize before you copy/migrate all data from one hard drive to another through cloning disk:
All data saved on the target hard drive will be cleaned, thus back up your necessary files in advance.
The capacity of the destination disk should be not smaller than the used space of source disk.
To boot successfully from cloned disk, it is necessary to change boot mode after you clone MBR system disk to GPT or GPT to MBR.
Then, connect the destination disk to your computer and make sure it can be recognized, and follow steps given below (Take cloning system hard drive to smaller one in Windows 10 as an example). You can download its demo version to have a try at first!
Step 1. Install and run AOMEI Partition Assistant Professional. In the main interface, select All Tools and Disk Clone Wizard.
Step 2. In the pop-up window, choose Clone Disk Quickly between two options.
Step 3. Here you need to choose a disk as source disk (Disk 1 is selected).
Step 4. After specifying the source disk, you need to choose destination disk (Here is Disk 2).
PS.: If your destination is SSD, tick Optimize the performance of SSD.
Step 5. In this window, you can choose Fit partitions to entire disk or Edit partitions on this disk. Then, click Next.
PS.: Clone without resizing partitions is grayed out as the destination disk is smaller than source disk, when it comes to cloning to larger hard drive or hard drive of equal size, the first option will be valid.
A Note about how to boot from destination disk will show up. Keep it in mind and click Finish.
Step 6. Here you can preview the result of operation. Click Apply to commit it..
You can easily transfer/copy all data from one hard drive to another under the help of AOMEI Partition Assistant Professional. And it is very helpful in managing partition and disk.
