2. **Locate Your M.2 SSD:**
* In the Disk Management window, you’ll see a list of all the storage devices connected to your computer. Identify your M.2 SSD. Be careful to select the correct drive, as formatting the wrong drive will result in data loss. You can usually identify it by its size, model number, or drive letter (if it has one assigned).
3. **Format the M.2 SSD:**
* Right-click on the disk representing your M.2 SSD.
* If the drive is uninitialized, you’ll see an option to “Initialize Disk.” Select this option and choose either MBR (Master Boot Record) or GPT (GUID Partition Table) as the partition style. GPT is generally recommended for modern systems, especially if the drive is larger than 2TB. MBR is suitable for older systems or smaller drives.
* After initializing, right-click on the unallocated space (represented by a dark bar) on the disk.
* Select “New Simple Volume…” This will open the New Simple Volume Wizard.
* Click “Next” to proceed.
* Specify the volume size. In most cases, you’ll want to use the entire available space, so leave the default value.
* Click “Next.”
* Assign a drive letter to the volume (e.g., D:, E:, F:). If you don’t want to assign a drive letter, you can select “Do not assign a drive letter or path.”
* Click “Next.”
* On the Format Partition screen, choose the following settings:
* **File System:** Select the desired file system. NTFS is the most common and recommended for Windows. exFAT is suitable for removable drives that you might use with other operating systems. FAT32 has limitations on file size (4GB maximum).
* **Allocation unit size:** Leave this as the default value (Default).
* **Volume label:** Enter a name for the drive (e.g., “M2 SSD”).
* **Perform a quick format:** This option is selected by default. A quick format is faster but doesn’t thoroughly erase all data. If you want to securely erase the data, uncheck this option. However, be aware that a full format can take a considerable amount of time.
* **Enable file and folder compression:** This option is usually not recommended for SSDs, as it can reduce performance and lifespan.
* Click “Next.”
* Review the settings and click “Finish” to begin the formatting process.
4. **Wait for the Formatting to Complete:**
* The formatting process may take a few minutes to several hours, depending on the size of the drive and whether you selected a quick format or a full format. Disk Management will display the progress.
* Once the formatting is complete, the drive will be ready to use.
### Method 2: Using Command Prompt (Diskpart)

* Type `select disk
* Diskpart will confirm that the disk is selected.
5. **Clean the Disk:**
* Type `clean` and press Enter. This command will erase all partition information and data from the disk. **This is a destructive operation, so make sure you’ve selected the correct disk!**
6. **Create a Partition:**
* Type `create partition primary` and press Enter. This will create a primary partition on the disk.
7. **Select the Partition:**
* Type `select partition 1` and press Enter. This will select the newly created partition.
8. **Format the Partition:**
* Type `format fs=ntfs quick` and press Enter. This will format the partition with the NTFS file system using a quick format. You can replace `ntfs` with `exfat` or `fat32` if desired. If you want to perform a full format, omit the `quick` option (e.g., `format fs=ntfs`).
9. **Assign a Drive Letter:**
* Type `assign letter=
10. **Exit Diskpart:**
* Type `exit` and press Enter to exit the Diskpart utility.
11. **Close Command Prompt:**
