It also can help in cloning hard disk drive under Mac OS. This software is very easy to use. No.5 Stellar Drive Clone for Mac. Stellar Drive clone for Mac is one of the best disk cloning apps for Mac. It creates an identical, ready to use copy of the hard drive. The clone software creates partitions in the same way as that of the actual hard drive.
Cloning is a destructive process that will erase the recipient drive, leaving the source drive intact.
The instructions below are for cloning from the original drive externally to a new drive inside a computer. In certain circumstances connecting the original drive externally is not an option. In those cases using an external hard drive as an intermediate is recommended. This process would consist of cloning the original drive while still inside the computer to a separate external hard drive, then installing the new drive and cloning the external hard drive to that new drive.
Power on the Mac while holding down the 'Option' key. This will display a boot menu that looks like the picture below. Click the drive icon that says 'Recovery' (OS 10.7 and later) or 'Mac OS X install' (OS 10.6.8 and earlier).

- Click the check box for 'Erasing destination.'
- Click 'Restore' at the bottom to begin the process of copying your data to the destination.
You can also restore one volume from another volume. When you restore from one volume to another volume, it makes an exact copy of the original. For example, you can restore from your startup volume to an external volume to use as a backup.
- Select the new drive volume in the sidebar then click the Restore button or choose Edit > Restore. This is the volume that is erased and becomes the exact copy.

It's not a matter of 'if,' it's a matter of 'when.' Sooner or later the hard drive on your computer will die, and the odds are that you will lose all your files stored on that drive.
Of course, there is a number of ways to prevent data loss. You can, for example, keep a current backup of your computer, you can make copies of your files to an external drive, or you can store your data in the cloud. However, similar to previous versions, Windows 10 includes a feature that let you mirror the data on one drive into another to offer data protection from a drive failure.
In Windows, we call the feature 'mirror,' but the concept actually comes from the standard RAID levels, which define a number of techniques to combine multiple hard drives to offer speed, redundancy, or performance.
On the standard RAID levels, 'mirror' is defined as RAID 1, and it consists of having an exact bit-to-bit replica of the data in another hard drive. Usually, a mirror setup contains two hard drives, but you can always add more, as long you add them in pairs.
In this Windows 10 guide, we'll walk you through the steps to create a mirrored volume on your computer to protect your data from drive failure.
Details before beginning
Before we dive in this guide, it's important to note that to create a mirrored volume on Windows 10, or with any operating system, you'll need at least two physical hard drives. Your second drive should be at least the same size as the original (a larger second drive is okay).
How to create a new mirrored volume
The instructions described below are to create a brand new mirrored volume where neither hard drive have any data.
To create a mirrored volume, do the following:
- Use the Windows key + X keyboard shortcut to open the Power User menu and select Disk Management.
Right-click one of the empty drives, and select New Mirrored Volume.
- Click Next.
- Select the available drive from the left.
- Click Add.
Specify the amount of space for the mirrored volume.
Important: The volume cannot be larger than the amount of the available space in the smaller hard drive, as you can't mirror data to space you don't have.
Click Next.
- Assign a drive letter or leave the default settings and click Next.
- Select Format this volume with the following settings option making sure file system is set to NTFS, allocation unit size is set to default, and you enter a name for the volume.
- Check the Perform a quick format option.
Click Next.
- Click Finish.
- Click Yes to convert the basic disks to dynamic disks, which is a requirement to create a mirrored volume on Windows.
Once the process completes, you'll only see one volume created, and as you store content on the new volume, the data will also automatically get replicated into the secondary drive.
How to create a mirrored volume with data already in the drive
The following instructions explain the steps to set up a mirrored volume when one of the drives already have data on it.
To create a mirrored volume with data already in the drive, do the following:
- Use the Windows key + X keyboard shortcut to open the Power User menu and select Disk Management.
Right-click the primary drive with data on it, and select Add Mirror.
- Choose the drive that will act as a duplicate.
Click Add Mirror.
- Click Yes to convert the basic disks to dynamic disks, which is a requirement to create a mirrored volume on Windows.
After completing the steps above, Windows 10 will synchronize the data on the primary drive to the second drive. This process can take a long time depending on the data you have stored in the volume.
How to recreate a mirror after drive failure
Once you set up a mirror, if either hard drive fails, you'll still be able to access your data. However, it's highly recommended that you replace the drive as soon as possible.
To recreate a mirror after a drive failure, do the following:
- Use the Windows key + X keyboard shortcut to open the Power User menu and select Disk Management.
Right-click the hard drive in working conditions on the mirror and select Remove Mirror.
- Select drive labeled Missing.
Click Remove Mirror.
- Click Yes.
Right-click the primary drive with data on it, and select Add Mirror.

- Select the new drive that will act as a mirror.
Click Add Mirror.
- Click Yes to convert the basic disks to dynamic disks, which is a requirement to create a mirrored volume on Windows.
After completing the steps above, Windows 10 will synchronize the data onto the new drive. Then simply repeat the process whenever a drive fails (which hopefully shouldn't be very often).
Wrapping things app
The primary purpose of a mirror setup is to provide data redundancy to protect your files from a hard drive failure. It's not designed to offer speed or performance like other RAID array levels.
Although mirroring can protect your data, it's not a replacement for a data backup. If you accidentally delete a file from one drive, the action will also replicate to the second drive.
Finally, it's worth pointing out that thanks to the Windows 10 flexibility, you can also use Storage Spaces to create a mirrored volume.
