How to Initialize SSD in Windows 10/8/7 with 3 Methods

This article will show you how to initialize SSD in Windows 10/8/7 with free third-party partition tools, Disk Management, or Diskpart command respectively.

Method 1: Use A Partition Master Tool - A Free Disk Management Utility

If you're not very computer literate, your best bet for disk management is to use a user-friendly disk management tool, so you don't risk damaging your computer by entering the wrong command line in something like Command Prompt.

With AOMEI Partition Assistant Free, you can initialize SSD with one click. It's that easy. Plus, this partition manager provides you with other one-stop partition and disk management solutions for your Windows PC as shown below.

Now, download this free partition manager and follow the steps below to initialize SSD in Windows 10/8/7. As for initializing SSD as GPT or MBR, you can read the next part.

Step 1: Run Partition Master and enter the main interface.

2. Right-click on the target drive - HDD or SSD, and select "Initialize as MBR" or "Initialize as GPT." Click "Perform Tasks" and "Apply" to save the changes.

0:00-0:18 Initialize as MBR; 0:19-0:44 Initialize as GPT;

After initialization, all disk space remains unallocated and therefore cannot be used for program installations or file storage. To use an MBR or GPT disk, you can proceed to create partitions and set up a file system with free partitioning software. Please refer to the following video tutorial for guidance.

Aside from initializing SSD and partitioning SSD, you can use the following features in the Partition Master tool to successfully manage and optimize SSD disk performance:

• Resize/Move Partition to optimize disk space (the Pro version allows you to directly transfer free space from one disk to another without deleting or formatting, such as moving space from D drive to C drive)
• Format SSD without any damage.
• Copies and clones an entire disk to another, even if the target partition is smaller than the source.
• Convert a logical partition to primary, or vice versa; convert FAT32 to NTFS partition; convert MBR disk to GPT, or GPT disk to MBR.
• Permanently wipe all data on the hard drive to prevent information leakage or recovery.

Method 2: Initialize the SSD Using Disk Management

Advanced or experienced Windows users can initialize and format an SSD using Disk Management, a free tool that's built into the operating system.

Step 1. In Windows 10/8, press "Windows + R" simultaneously, type "diskmgmt.msc", and click OK to launch Disk Management. In Windows 7, right-click "Computer" and select "Manage" to run Disk Management.

Step 2. Right-click the SSD you want to initialize and select "Initialize Disk." If the disk is offline, right-click it first and select "Online."

Step 3. Similar to initializing an HDD, you should select the correct disk to initialize in the "Initialize Disk" dialog. Then click "OK" to accept the default partition style (GPT or MBR), or change it as needed.

In this article, we'll provide you with five effective solutions (step-by-step guides) to help you fix the "Can't initialize disk" issue in Windows 11/10/8/7.

Method 3: Initialize SSD using the Diskpart Command

Step 1: Open the Start menu, type diskpart, and press Enter.

Step 2: Type one of the following commands to initialize the disk as MBR or GPT, and then press Enter.

List Disks > Select Disk # > Convert to MBR/GPT

Step 3. To create a primary partition directly on an MBR disk, type:

List Disks > Select Disk # > Clean > Create Primary Partition > Format fs=ntfs Quick > Assign > Exit This is a step-by-step process to manipulate a hard drive in the Command Prompt for cleaning and formatting. Replace "#" with the disk number you wish to operate on.

To create a primary partition on a GPT disk, use the following command:

Here are the commands in Chinese for operating on a disk in a command line, translated into English: 1. List disks > 2. Select disk # (where # represents the disk number) > 3. Clean the disk > 4. Convert to GPT format > 5. Create a primary partition > 6. Quickly format as NTFS file system > 7. Assign a drive letter or path > 8. Exit Make sure to back up important data before proceeding, as these commands can result in data loss.

These instructions might be a lot to take in, so feel free to share this whole tutorial to help others out.

MBR vs GPT | How to Initialize an SSD as MBR or GPT

MBR and GPT are two common partition styles on Windows computers. MBR stands for Master Boot Record, while GPT stands for Globally Unique Identifier Partition Table. The advantage of GPT (GUID Partition Table) is that it's more robust and supports 4KB alignment, which is beneficial for solid-state drives (SSDs).

The Master Boot Record (MBR) only supports partition sizes up to 2 TB and limits you to four primary partitions. GPT disks, however, support volumes larger than 2 TB and have no limit on the number of partitions you can create. Windows 7 uses MBR for partitioning by default, but Windows 8 and 10 are recommended to use GPT.

The choice of partition style largely depends on whether your computer boots in BIOS mode or UEFI mode. The common configurations are BIOS+MBR or UEFI+GPT.

Additional Tip: How to Convert SSD from MBR to GPT or GPT to MBR Without Losing Data

You can choose to initialize the SSD as MBR or GPT, depending on the disk size, the system boot mode, and the number of partitions you need.

However, sometimes you need to convert the disk style, for example, when you get the error message "Windows cannot be installed to this disk. The selected disk has an MBR partition table" or "Windows cannot be installed to this disk. The selected disk is of the GPT partition style" when installing the Windows OS on your computer. In this case, converting the initialized SSD from MBR to GPT or from GPT to MBR will help resolve the issue.

The following steps show you how to convert MBR to GPT with the Partition Master tool. The procedure is the same to convert GPT to MBR.

1. I just bought a new solid-state drive, but it's not showing up in File Explorer.

If you insert a new blank Solid State Drive (SSD) on your Windows 10/8/7 computer and can't see it in File Explorer, chances are that you need to assign a drive letter to it or initialize it before using it.

2. You receive an error message that reads "Disk Unknown, Not Initialized".

Sometimes when you try to access an SSD, you may receive the “Disk 1 Unknown, Not Initialized, Unallocated” message. When this issue occurs in Windows 10/8/7, you need to find a way to initialize the disk properly.

3. You receive the error "You must initialize a disk before Logical Disk Manager can access it."

When you connect an SSD to your computer and it doesn't show up in My Computer/This PC, you might see this error when you check in Disk Management. To fix the problem, you need to initialize the disk and format it with a file system so that you can start using it.

A quick guide to initializing an SSD: 1. **Connect the SSD**: First, ensure your solid-state drive (SSD) is correctly connected to your computer. For desktops, this usually means installing it into a SATA slot on the motherboard. For laptops, you might need an adapter or to replace the existing hard drive. 2. **Boot into BIOS**: Restart or power on your computer, then press a specific key repeatedly during startup (usually F2, F10, F12, or Delete, depending on your computer brand) to enter the BIOS settings. 3. **Check the SSD**: In the BIOS, locate "Device Management" or "Storage Configuration" and confirm that your system detects the newly connected SSD. 4. **Set boot order**: If you plan to use the SSD as the primary drive, you'll need to adjust the boot order in the BIOS, putting it at the top. 5. **Save and Exit**: Follow on-screen prompts to save your changes and exit the BIOS. Your computer will restart. 6. **OS Installation**: Upon reboot, assuming everything is working correctly, your computer should boot from the installation media (like a Windows install disc or USB). Follow the on-screen instructions to install the operating system. 7. **Partition and Format**: During installation, choose a custom setup and partition the SSD. Select an appropriate partition size and make sure to choose the correct file system (like NTFS) and formatting options. 8. **Initialization Complete**: Once the installation is complete, the operating system will automatically initialize the SSD. Now, you're ready to start using your brand new SSD. Keep in mind that these steps may vary slightly depending on your computer and operating system. Be sure to consult relevant documentation for specific guidance.

After reading this post, you should know how to initialize SSD. Generally, there are 3 ways to initialize SSD: with Partition Master – a free Windows partition manager, Disk Management, or Command Prompt. We highly recommend using Partition Master for its convenience and safety. It's easy to manage disks or drives whether you are a beginner or expert.

Frequently Asked Questions on How to Initialize SSD in Windows 10 (UTF-8)

Here are four highly relevant questions about how to initialize an SSD. If you have any of these issues, you may find your answers here.

Do I need to initialize the SSD before cloning?

Do I need to initialize SSD before cloning? If you are performing a clean install of the operating system or cloning HDD to SSD, both procedures will initialize and format the new SSD during the process, so there is no need to do it beforehand.

Should I initialize my SSD as MBR or GPT?

MBR and GPT employ different interfaces. MBR supports a maximum partition size of 2 TB and allows the creation of only four primary partitions. In contrast, GPT disks can accommodate volumes larger than 2 TB and, in theory, an unlimited number of partitions. Additionally, GPT disks offer better security features. When choosing between MBR and GPT, you can learn more about their differences and which one might be better suited for your needs.

Moreover, you can use the tools of Partition Master to convert MBR to GPT without formatting.

Why isn't my SSD drive showing up?
