Preparation Before M.2 SSD Replacing

#️⃣Choose an M.2 SSD

M.2 SSD has two types: SATA M.2 SSD and NVMe M.2 SSD. They differ in terms of interface, speed, price, etc. Before replacing it, you need to distinguish them clearly before deciding which SSD to use:

#️⃣Select a disk cloning tool and clone data to the new M.2 SSD

A disk cloning software can duplicate the original M.2 SSD and assist you in replacing and upgrading the M.2 SSD without reinstalling the Windows operating system, settings, installed applications, etc.

It is a pity that Windows OS doesn't have a built-in disk cloning utility, so finding a reliable and effective SSD cloning tool is crucial for SSD replacement. EaseUS Disk Copy is a robust disk cloning tool that can help you clone and move all data from the old M.2 SSD to the new one. It also comes with the following features to make it your perfect choice:

• Clone smaller SSD to larger SSD, and vice versa.
• Compatible with M.2 SSD, SATA SSD, NVMe SSD, general SSDs, HDDs, etc. 
• Support cloning with bad sectors.
• Support sector-by-sector cloning to copy only used space.
• Eliminate the SSD formatting step to save time and effort.
• Both Disk mode and partition mode.
• Clone HDD to M.2 SSD.
• Automatically detect and monitor the source target disk size and adjust the partition.

Now download it and get prepared to start the M.2 SSD replacement.

EaseUS Disk Copy only requires several simple clicks to finish the disk cloning process. Before cloning, connect the new M.2 SSD to your computer or laptop through a SATA to USB cable or an adaptor, and make sure it is recognized correctly.

Prior Notice:

• The "Sector by sector copy" asks the size of your destination disk to be at least equal to or larger than that of the source disk. Leave this feature unchecked if you wish to clone a larger hard disk to a smaller hard disk.
• All data on the destination disk will be completely erased, so take care.

Step 1. To start copying/cloning an entire disk to another, choose this disk as the source disk under "Disk Mode" and click "Next".

Step 2. Choose the other disk as the destination disk.

Step 3. Check the disk layout of the two disks. You can manage the disk layout of the destination disk by selecting "Autofit the disk", "Copy as the source" or "Edit disk layout". 

• "Autofit the disk" makes some changes by default on the destination disk layout so that it can work at its best status.
• "Copy as the source"does not change anything on destination disk and the layout is the same as source disk.
• "Edit disk layout" allows you to manually resize/move partition layout on this destination disk.

Tick the "Check the option if the target is SSD" option to put your SSD in its best performance.

A message now appears, warning you that data will be lost. Please confirm this message by clicking "OK" and then click "Next".

Step 4. Click "Proceed" to officially execute the task.

How to Replace M.2 SSD: Step-by-Step Guide

The process of replacing M.2 SSD involves seven simple steps. When all the above preparations are done, follow the guide below to start:

Step 1️⃣. Shut down your computer and disconnect the power cable.

You need to ensure that the operation is performed in a safe environment.

Step 2️⃣. Open the case of your desktop.

Use a screwdriver to open the desktop case or the backup cover of the laptop. The case opening process may vary depending on your specific desktop model. You can consult the user manual or manufacturer's website for instructions on opening your case.

Step 3️⃣. Find the motherboard and locate the M.2 slot on your motherboard.

It is a small slot specifically designed for M.2 SSDs. You can also refer to your motherboard's manual to identify the exact location and specifications of the M.2 slot.

Step 4️⃣. Remove the original M.2 SSD.

Depending on the design of your motherboard, this may involve unscrewing a retention screw that holds the SSD in place or releasing a clip. Pull the SSD out of the slot gently.

Step 5️⃣. Install the new SSD, and make sure it is fully seated.

• Attach any heatsinks or thermal pads that came with the SSD if necessary. These aid in heat dissipation and performance. 
• Align the SSD's notches with the slot and gently insert it at an angle. To fully seat the SSD in the slot, use light pressure. Don't push it. 
• If there is a retention screw, secure the SSD in place by tightening the screw. Be careful not to overtighten.

Step 6️⃣. Close the case of your computer and reconnect all cables.

Use a screwdriver to close the case or the back cover, then reconnect all cables to restart your computer.

Step 7️⃣. Enter the BIOS settings to change the boot order.

While restarting, press F2/F8/Del Kkey to enter the BIOS settings. Navigate to the boot settings and ensure the new M.2 SSD is recognized as a bootable device. When it finishes, save the changes and exit the BIOS settings, and your computer will boot from the new cloned M.2 SSD successfully.
