How to expand drive capacity / Clone (copy) and replace

If your hard disk or SSD is running low on capacity, you can clone (copy) it to a larger capacity disk and replace it. You can even expand the capacity of your C drive, which is the Windows startup drive, by cloning and replacing it. Once the cloning is complete, you can continue using Windows as before by simply replacing the SSD.

Time it takes to clone (copy)

The time it takes to clone (copy) depends on the amount of data to be copied and the access speeds of the source and destination disks. In my tests, it took about two hours to copy a 2TB SSD (about 1.5TB of data) to a 3TB hard disk, and about five hours to copy it to a 4TB SSD.
SSDs in particular take a long time to write to, and writing large amounts of data can cause degradation due to heat generation. To avoid mistakes and rework, and to verify the procedure, we recommend testing the procedure on a blank hard disk before making the actual copy.

What is Macrium Reflect Home?

Macrium Reflect Home is a software developed by Macrium Software that can back up and restore disks on Windows computers. It is a highly functional software that can automatically take backups according to a schedule and restore in the event of a crash.
One of the many features it has is the ability to clone (copy) a disk. You can even copy the entire Windows boot drive. Even if you have created multiple partitions (drives) on a single hard disk or SSD, you can rearrange the layout of each partition or make detailed changes to their capacity before copying them.
Macrium Reflect Home is a paid software that costs USD 49.99 per year or USD 79.99 for a one-time payment, but a 30-day free trial is available. I think the free trial is sufficient for many users. It's an excellent software, so it's worth purchasing, but it's a bit expensive for just cloning a disk. It would be nice if they offered a cheaper software that focuses on the cloning function...

Preparing the New SSD Drive

First, prepare a new disk to copy to. There are many types of M.2 SSDs, including 2280 / 2260 / 2242 / 2230 sizes, single-sided / double-sided component mounting methods, M Key / B Key / B&M Key connector shapes, and NVMe / SATA / AHCI interfaces. Check the specifications of the SSD that can be installed in your computer. Most recent computers are compatible with "2280/single-sided/M Key/NVMe."
You will also need to prepare a USB-connected SSD enclosure (case) to house the destination SSD during copying. The speed specifications of the USB you connect are important. If your computer has a USB 4.0 port, you will be able to copy faster if you use an SSD enclosure that is also compatible with USB 4.0.
The disk prepared this time is a Samsung 990 PRO 4TB (Amazon.com) with 2280/single-sided/M Key/NVMe, and the SSD enclosure is the UGREEN M.2 SSD Case 15976-40GB (Amazon.com) which is compatible with USB 4.0.

Clone C drive SSD

This section explains the procedure for cloning an SSD that includes a C drive with Windows installed. In this example, the source disk is a 2TB SSD. Only 300GB is allocated to the C drive, with approximately 1.5TB of the remaining capacity going to the D drive, and the rest being the system area, recovery area, etc. To copy this to a new SSD, I will expand the C drive to approximately 1TB and add the remainder to the D drive.

Click the icon on the desktop to launch Macrium Reflect Home.
Analysis of the disks connected to your computer will begin, and after a while you will see the screen shown on the right. A list of the disks connected to your computer is displayed.
By default, the top disk in the list is selected. Beneath the selected disk is a menu that reads "Clone this disk."
The disk we will be cloning this time is the second disk which contains the C drive, so click on that icon.

"Disk 2" is selected. Next, click "Clone this disk."

Click "Select a disk to clone to".

A list of disks will then be displayed. Select the disk you want to copy to.

Drag and drop all partitions from the source disk to the destination disk. The only partitions visible to the user on this disk are drive C (No. 3) and drive D (No. 4), but we'll start by allocating all partitions in this order.

Once you've dragged and dropped all the partitions, you'll see the screen on the right. Because the destination disk has a larger capacity, free space is shown in grey on the far right.
Move the No.5:Recovery partition, which is at the far right (back), to the very back of the disk. Click on the Recovery partition, then click "Float Right" from the icons at the top.

Partition No. 5 has been moved.
Next, we will expand the space of the D drive (No. 4). Click on the No. 4 partition and then click "Layout" from the icons at the top.

The properties screen for the selected partition will open. You can change the partition size by dragging the slider in the Size column left or right. Once you've specified the size, click "OK".

The size of partition No.4 has been increased. Next, click "Float Right" from the icon at the top.

Partition No.4 has been moved.
Finally, Enlarge the No.3:C drive partition. Click the C drive partition to select it and click "Fill Space" from the icon above.
"Fill Space" will expand the selected partition to fill the entire free space.

Partitioning of the new disk has been completed. Click "Next" at the bottom right of the screen.

The message on the right will be displayed. It seems to mean that if you want to specify BitLocker (encryption), you will have to specify it yourself after copying.
This message appears even if the source disk does not contain a partition encrypted with BitLocker.

Next, you'll see a screen like this. If you want to repeat the cloning task you just set up on a regular basis, you can set up a schedule on this screen.
Since we will not set a schedule, click "Next" at the bottom right of the screen.

Details of the cloning operation you just set up will be displayed. Check the details, and if there are no problems, click "Finish" at the bottom right of the screen.

Next, you will see a screen like this. Click "OK".

If the destination disk is not empty, you will see a warning message like this. Check "All data on the target volume will be overwritten..." and click "Continue".
This message will appear even if the destination disk contains empty partitions. It will not appear if the destination disk is a brand new, unallocated disk.

Once you get to this stage, the disk copying will finally begin. The date and time when the copying process began will be displayed at the top of the screen.
The disc will become very hot during copying. To prevent deterioration of the disc, use a small fan or similar to cool your computer and the destination disc.

Once the copy is complete, you will see a message like this.

Click "Close" at the bottom right of the screen.
Copying is now complete. Turn off the computer and replace the source disk with the destination disk.

Switching the display language

Click on the "Defaults" icon in the top left of the screen.

You will then see a screen like this. You can change the display language in the [Advanced Settings] - [Language] - [Language] section.
