Why clone hard drive to larger drive?

Obviously, cloning hard drive to larger drive solves the low disk space warning issue and has the following advantages. Try this method if you want to get enjoy one or more of them:

👉 Get more space. If you replace your smaller disk with a larger one, you can obviously install more programs, and store many data on it. 

👉 Boost computer performance: Usually, The more free space on the system disk, the smoother it will run, for example, has a short boot time, run multiple programs without sticking, etc. SSD disks will be more obvious as it has much faster read or write speed than HDDs.

👉 Replace old or damaged disks: In this case, you have to replace them. Otherwise, it will either affect the performance or break down completely.

👉 Double data protection. You can also use the cloned drive as a backup copy, which allows you to get your files back quickly in a disaster, such as system crashes, virus attacks or malware, BSOD, etc. 

Prepare for your new hard drive or SSD disk

Well then, how to clone disk to larger drive with it? Connect the new disk to your Windows 10 or 11 computer, and clone it with a reliable disk clone software. Before that, you need to prepare this new hard drive or SSD disk. 

Check the number of disk slots and interfaces

Open your computer case and check if you have one more slot. Usually, most HDDs use the SATA interface while SSDs may have different interfaces, such as SATA, M.2, PCIe, NVMe, etc.

Get a new hard drive

 It can be HDD or SSD, depending on your purpose, larger capacity, or and better performance. If you have more budget, SSD will be a better choice. Below are some key factors:

• The capacity is twice or three times that of a smaller drive.
• Check the number of disk slots and interfaces. 
• Prepare a new connector if your laptop or desktop only has one slot. Select it based on your interface, such as SATA, M.2, PCIe, NVMe, etc.

Install new hard drive 

• For the desktop or laptop with two slots, you can directly install the new hard drive on the extra socket. Slide the new drive into the slot, screw it tightly, and put the computer case back.

• For a laptop with only one slot, you will connect your new drive using a cable or adapter, for example, SATA-to-USB, or put it into the enclosure, and connect the other side to your computer.

Initialize disk in Disk Management

Any disk needs to be initialized and partitioned to store data. You can choose to initialize this new disk with MBR or GPT partition style, depending on the disk type of your smaller disk.  

• Type diskmgmt.msc in the search box and select Run as administrator.
• Locate and right-click the smaller disk and select Properties. Then, check if it is MBR or GPT.

• Then, right-click the larger disk and select Initialize Disk.
• Select MBR or GPT disk partition style and click OK. Note it must be the same as your smaller disk.

👉 Alternatives: If you don't have any connector, you can still choose to backup Windows to NAS, then swap your smaller disk to a larger disk and restore the backup image.

One powerful hard drive or SSD cloning software

Please wait after preparing, since you still need one powerful disk cloning software, AOMEI Backupper Professional, for example. It provides you with 2 practical ways to clone smaller disk to larger disk including the operating system, boot files, personal data, installed program, etc.

#1: Disk Clone: recommended for a quick upgrade

With it, you are able to clone disk to larger disk, clone SSD to larger SSD, clone large HDD to smaller SSD, clone a hard drive in Windows 10, and even clone hard drive with bad sectors without reinstalling Windows. To clone OS to new drive, try its "System Clone" feature.

#2: Disk Backup and Restore: focus on data protection and require more effort

Its "Schedule Backup" feature will back up the entire disk automatically, minimizing the data loss risk if you forget to backup disk & data. By default, the "Incremental Backup" feature will be enabled in scheduled tasks, saving disk space. To further optimize it, the "Backup Scheme" feature will do a big favor.

Top 2 ways to clone disk to larger disk in Windows 10 or 11

In this part, I'll introduce you both methods to clone smaller disk to larger disk or SSD. Please note that this software only supports Windows 11/10/8/7/XP/Vista. For server users, try AOMEI Backupper Server.

👉 Try Method 1 if you want a fast way to clone a hard drive.

👉 Try Method 2 if you are more concerned about data security and want to protect it continuously. This is the safest way. 

Method 1: Clone smaller disk to larger disk with Disk Clone 

Step 1. Open AOMEI Backupper Standard, click Clone and Disk Clone subsequently. 

Note: The Clone feature can only be demonstrated in the trial version. If you want to directly clone HDD to Samsung SSD or other disk brands, please upgrade Pro trial to the full version of AOMEI Backupper Professional.

Step 2. Select your source disk (here is Disk0)and then the destination disk (here is Disk1). Click Next in order after selecting disk. 

Step 3 (Important). Click Edit Partitions to clone and resize hard drive with the following 3 options. Besides, if the source disk and destination disk has different disk type, you will also see "Convert the destination disk from MBR to GPT" or vice versa. Please check it if the following window shows.

• Copy without resizing partitions: It will not resize the partition size.
• Add unused space to all partitions: It will reallocate the unallocated space to each partition of the target disk, appropriate for the disk size.
• Manually adjust partition size: It allows you to extend unallocated space to any partition on the destination disk you want. 

📔How to check disk type (MBR or GPT) of a disk:

If you want to be sure both disk types, and boot from the cloned drive successfully, you can refer to the overall steps in the following:

• Press Win + R to open the Run window. Then, type diskmgmt.msc and hit OK to open disk management.
• Then, right-click the disk you want to clone and select Properties in the pop-up window.
• In the Properties window, select the Volume tab and confirm the partition style. It can be MBR (Master Boot Record) or GPT (GUID Partition Table).

• Similarly, check the disk partition tyle of the destination disk. If they have different disk partition style, please convert MBR to GPT or vice versa with Edit Partitions option.

Step 4. Check "SSD Alignment" to optimize performance of SSD disk if you are cloning disk to larger SSD.  Then, confirm the details of both disks and click Start Clone.

Now, you may already clone hard drive to larger drive successfully, you can try to boot from it. But if your destination disk is smaller, the cloning process may fail. In this case, you can choose to migrate OS  only with "System Clone" feature. 

Method 2: Copy boot drive to larger drive with Disk Backup & Restore

Except for cloning HDD to larger HDD or SSD with "Disk Clone" feature, you still can use Disk Backup & Restore in AOMEI Backupper. And it focuses on continuous system and data protection - backup all the data currently on the disk and changes made later automatically. 

Part 1: Backup a hard drive in Windows 10

Step 1. Open AOMEI Backupper Standard, click Backup and Disk Backup.

Step 2. Select the source disk you want to backup and the destination disk to store the backup image.

Step 3. Set daily, weekly, or monthly scheduled backup, and once it is enabled, this software will backup only changed files in a scheduled task. Besides, you still can use the Event trigger and USB Plug in features for specific scenarios.  Finally, click Start Backup to complete this task.  

📔 Important: good and sustainable data protection

AOMEI Backupper will continuously create backups for your computer until the backup disk is full. To avoid this, try to enable automatic backup cleanup in Backup Scheme. It will delete backup files automatically to free up disk space for new backups.

Part 2: Restore disk image to get computer back quickly

 You don't need to restore disk backup immediately after backing up and do this in a disaster or it behaves abnormally. This process will also include the Edit Partitions to help you make full use of disk space and avoid boot failure due to different disk types.

 Step 1. Connect both backup disk and new drive to receive backup image. Then, open this software, click Restore and Select Task in order.

Step 2. Then, you will be asked to select the disk image, restore items and destination disk. Just do so and click Next in each step. 

Step 3 (Important). Click "Edit Partitions" to adjust partition size on the destination disk. If you mover Windows to new computer, please check the "Universal Restore" to ensure a secure boot. It will install all the necessary drivers required to start a PC.

Step 4. Preview the details and click Start Restore to restore disk backup to new hard drive. If your target disk is an SSD, please tick "SSD Alignment" to make your SSD achieve its best performance.

📔 Advanced feature:  Explore Image - restore only individual files from a disk 

AOMEI Backupper has a "Explore Image" tool that allows you to perform hard disk image file restore.  With it, you can assign drive letters for all or some of the partitions on the disk and mount the backup image in Windows Explore.
