Many PC and laptop users have experienced the frustration of an M.2 SSD failing to be recognized. This issue is more common with NVMe SSDs, although it can also occur with M.2 SATA drives. M.2 drives are sometimes invisible to the BIOS, while other times they are visible to the BIOS but invisible to Windows.

Frequently, compatibility and configuration concerns are to blame. The driver, the operating system, and, in rare cases, a faulty solid-state drive all play a role in this issue. If you're having trouble with this problem, we've got a list of the potential reasons and solutions below. So, without further ado, you can fix M.2 SSD Not Showing Up In Disk Management Windows 11.

Guide to Diagnose M.2 SS Problems on Windows 11 Quickly 

The moment you get this problem, you will want to fix this. While there are many fixes, we must first focus on what leads to M.2 disk not showing on Windows 11 - it causes! Besides, you can share this article by clicking the buttons below to let more users know why they get this error.

  • Virus or Malware infects SSD - Try anti-virus software if this is the difficulty you're having.
  • SATA Storage Controller Mode/Protocol is Wrong - It's possible that your motherboard storage controller and IDE ATA controller drivers need to be updated or uninstalled to fix your problem.
  • SSD is Facing Driver Issues - One of the possible causes of an SSD disk not showing up in Windows 11 is a driver problem. Both the "Hardware and Device Troubleshooter" and the Device Manager are available in Windows 11 for troubleshooting issues with hardware and devices.
  • SSD Has Hidden Partitions - There is a good chance that if you can't view your SSD disk partitions, they're concealed. Partitions are hidden, and you need to make them visible again.
  • The Drive Letter of SSD Partition is Missing or Conflicted - Device Manager or Disk Management can show an SSD, but Windows File Explorer doesn't. The drive letter can have been lost. In Windows 11, you're supposed to be able to choose a drive letter.
  • The File System of SSD Drive Cannot Be Recognized - NTFS or FAT32 is the best option for running Windows 11 on your machine. You'll need to format the drive to NTFS or FAT32 to avoid this.
  • SSD Partitions Are Lost and Become Unallocated Space - Your disk can be labeled as either Not Initialized or Online. The first thing you need to do if you lose a Windows 11 is to recover it.
  • New SSD is not Initialized - If it is a fresh SSD drive that has not yet been partitioned, it will not appear in Windows 11. In this situation, you can start it up. The quickest method to do this is to utilize the built-in Disk Management in Windows. "diskpart > list disk > choose disk n (n corresponds to the drive number of the new SSD) > characteristics read-only> online disk > convert MBR" (or convert gpt) in the command prompt and push Enter to start it.

It may be the time for you to do a thorough hard disk health check for your computer.

FIX 3. Initialize SSD in Disk Management

One of the reasons behind the problem was that you could not initialize your SSD in the system. Here's how you can do that:

Step 1: To access Disk Management, connect the SSD to the computer and click on the Disk Management icon. Select Disk Management from the Start menu by selecting it with the right-click mouse button.

select disk management from start menu

Step 2: If you have not yet initialized the SSD, you will see that it is labeled as Not Initialized. As seen below, right-click it and pick the Initialize Disk option from the menu:

initialize the disk

Step 3: Select a partition compatible with both the MBR (Master Boot Record) and the GPT (GUID Partition Table) and press the OK button.

Step 4: Select New Simple Volume from the context menu of the SSD. The wizard will guide you through the process of creating a partition and assigning a drive letter to your SSD.

Note: In rare instances, the SSD can be inaccessible. You can make it reactive again by right-clicking it and selecting Online from the context menu.

FIX 4. Update Your Storage Controller Drivers

One of the major reasons your M.2 doesn't show up in Windows is old storage controllers that aren't updated. Here's how you can update their fix:

Step 1: Device Manager can be accessed by right-clicking the Start menu and selecting it.

Step 2: Locate the Storage controllers in Device Manager once they appear. Update the driver by selecting it from the context menu.

update windows driver

Step 3: With the option to search automatically for updated driver software selected, Windows will search your computer and the Internet for the most recent drivers available.

Step 4: After the new drivers have been installed, the computer should be restarted.

FIX 5. Examine Cables and Connections of Your System

In most cases, SSDs are linked to motherboards by SATA cables, and if the connections are damaged, the device will not be identified by the computer or even by the BIOS.

To rule out a cable problem, you can connect the SSD through a separate connection. Some SSDs do not need a connection to be attached, such as the M.2 SSD placed into a slot on the motherboard.

Whether this is the case, you can try installing the SSD on a separate computer to see if it is detected there.

FIX 6. Format the Disk to NTFS

Whether the file system is the problem, you can attempt to format it to NTFS using Diskpart or a third-party program to see if it solves the problem. First, you can use DiskPart.exe to reformat the disk to a file system compatible with your operating system.

Step 1: cmd should be typed into the search box, then right-clicked and selected Run as administrator.

Step 2: In the command prompt, type diskpart and press the Enter key.

Step 3: Enter the following instructions into the text box and Enter.

  • list disk
  • select disk n (n refers to the number of the disk containing unsupported or corrupted file system)
  • clean
  • create partition primary
  • Format fs=ntfs

Step 4: To quit Diskpart, type exit and check to see whether it worked.


After reading this article, you will understand that SSDs not showing up on Windows 11 can be caused by various factors. The probable reasons and remedies are discussed in detail in this article. You can test each of the possible options one at a time.

If you don't want to lose your data, please attempt to format the disk at the very end. EaseUS Partition Master is highly recommended for creating new partitions and labeling partitions with various letters, among other things.
