This comprehensive guide presents 4 proven approaches to transfer data from one internal hard drive to another efficiently and safely. Each method offers different advantages depending on your specific needs and technical comfort level.

Why You Need to Transfer Data from One Internal Hard Drive to Another

Many users find themselves in situations where they need to transfer data from one internal hard drive to another. A common scenario involves upgrading from a smaller drive to a larger one when storage space becomes limited. For instance, if your current drive is nearly full with 200GB of data, the traditional copy-paste method might seem risky and time-consuming.
Modern internal hard drives with expanded storage capacity can significantly boost your computer’s performance and give your system a fresh start. When your existing drive reaches capacity, transferring data to a larger internal hard drive becomes not just convenient, but necessary. Upgrading to a larger hard drive—not just expanding free space—can dramatically improve system performance. Switching to an internal solid-state drive, especially a 2025 M.2 SSD with the latest Gen 4 NVMe protocol, delivers a noticeable boost in speed and responsiveness.
Additionally, if your Windows system crashes with a blue screen error and won’t boot, transferring data becomes critical for recovery. In these cases, specialized tools or bootable environments may be needed to access and preserve your files before reinstalling or upgrading the operating system.

2. Configure Advanced Settings and Begin Cloning
Before starting the clone operation to transfer data from one internal hard drive to another, Renee Becca provides customization options through these advanced features:
- ‘Copy all the sectors’ capability
This feature allows you to copy all sectors from the source disk to the target disk, including reserved areas and unused space. In some cases, software may store license information in reserved sectors, which are usually skipped during a standard cloning process—this option ensures even those areas are included when you transfer data from one internal hard drive to another.
- Universal disk type compatibility
Renee Becca maintains compatibility with diverse HDDs, SSDs, and USB devices. Regardless of your specific hard drive and USB combination, you can successfully transfer data from one internal hard drive to another.
- Customizable disk layout configuration
You can resize the partition by clicking and dragging its edge with your mouse based on your specific requirements when you transfer data from one internal hard drive to another.
adjust partitions 
Finally, once you’ve configured your preferred settings, click the “Clone” button to begin the cloning process and transfer data from one internal hard drive to another.
Option 2: For System-Only Migration, Use the ‘System Redeploy’ Function
Launch the application and select the “System Redeploy” option in the main interface under the “Clone” column. This feature is specifically designed for migrating your entire Windows system when you need to transfer data from one internal hard drive to another efficiently.

The software will begin transferring your entire system, including the operating system, applications, settings, and personal files to the new SSD/HDD when you transfer data from one internal hard drive to another. Monitor the progress carefully during this critical phase of your upgrade.

Step 3: Wait for Complete Migration

The duration depends on your source disk’s data volume, typically ranging from 30 minutes to several hours. Once completed, your new SSD/HDD will contain an exact copy of your original system, ready for use after you successfully transfer data from one internal hard drive to another.
Important Note: The total capacity of the new drive needs to be greater than the size of the system being migrated. Since all data on the target disk will be erased during the system migration, please verify that you’ve selected the correct target drive and backup any important data beforehand. If you want to migrate all data from the original system drive (not just the system partition) to the new drive, you can choose the hard disk clone function instead.

Step 4: Verify Your New Drive Status

After you transfer data from one internal hard drive to another, use software like CrystalDiskInfo to verify your new drive status.
CrystalDiskInfo – Monitors the health and status of your hard drives and SSDs using S.M.A.R.T. (Self-Monitoring, Analysis, and Reporting Technology) data. In a word, it helps users quickly identify second-hand or fake SSDs.

After successfully using this method to transfer data from one internal hard drive to another, you can safely delete the original data to free up storage space and optimize your system’s performance.

Method 2. Manual Copy and Paste to Transfer Data from One Internal Hard Drive to Another

Suitable for transferring small files individually, though interruptions may cause data loss
While professional cloning software offers the most robust solution, you can also transfer data from one internal hard drive to another using the traditional copy-paste method. This approach works best when you need to transfer data from one internal hard drive to another for smaller amounts of information, typically under 30GB.
The manual method to transfer data from one internal hard drive to another is free and straightforward, but it comes with limitations. Large file transfers can be time-consuming and prone to errors, and any interruption during the process might result in incomplete data transfer.
Step 1: Prepare the destination drive for data transfer.
Navigate to your new internal hard drive and either select an empty partition or create a new one specifically for the data you’re planning to transfer from one internal hard drive to another.
Step 2: Select the data you want to transfer.
Open your source internal hard drive and choose the files you need to move. You can press Ctrl + A to select everything or choose specific files and folders to transfer data from one internal hard drive to another selectively.
To see hidden files in Windows File Explorer, make sure your settings are configured to display them. In File Explorer,go to View > Options > Show hidden files
