How to copy data from one hard drive to another easily?

There will be two ways described below. If you are moving files such as documents, pictures and music from the PC hard drive to another drive, you can turn to Way 1. If you are transferring files along with programs and operating system to a new drive, you may resort to Way 2.


  • Connect the target hard drive to your computer and make sure it is detected.

  • Download and install AOMEI Backupper.

Way 1: copy files from one hard drive to another

1. Launch AOMEI Backupper. Click “Backup” and select “File Sync”.

>> Options: you can write a comment for your sync task so that you can figure out the specific sync contents. You can also enable email notification here.
>> Schedule: you can set the sync task to run periodically. There are six modes provided: Daily, Weekly, Monthly, Event triggers, USB plug in and Real-time sync. Please upgrade to AOMEI Backupper Professional to enjoy the last three modes.

Way 2: copy all data from PC hard drive to another drive

Note: If there are important data on the target drive, please backup files before you try Way 2, because all the data in the destination will be overwritten in the cloning process.

1. Run AOMEI Backupper. Click “Clone” on the left pane and select “Disk Clone”.

Disk Clone

Tips: The Standard edition only supports cloning the system disk to another disk with the same partition style (MBR to MBR or GPT to GPT). If you are cloning to a different partition style, you may try higher editions.

2. Select the original hard drive on your PC as the source disk and click “Next”.

Select Source Disk

3. Select the destination drive you have connected to your PC and click “Next”.

Select Destination Disk

4. Confirm the operation and click “Start Clone”.

Start Clone

>> Edit Partitions: you can choose to resize partitions on the destination disk or not here.
>> SSD Alignment: it will improve the reading and writing speed of the SSD. Use this option if the destination disk is an SSD.
>> Sector by sector clone: it will clone every sector on the source disk no matter it is used or not, thus costing more time. It requires the destination disk to be equal to or larger than the source disk.

5. After the cloning process is finished, you need to change boot order in BIOS or replace the source drive with the cloned one to boot from it.
