Scenario
This topic uses Windows Server 2019 Data Center 64-bit Chinese Edition as an example to describe how to initialize data disk on Windows.
Description
The formatting operation may differ depending on the operating system of the physical server. For more information on steps and differences, refer to the respective OS documentation.
Before You Begin
The data disk mounted to the physical server or local data disk of the physical server has not been initialized.
Operation Steps
If the capacity of the new data disk is less than 2 TB, initialize the Windows-based data disk in two steps as follows:
l Log in to the physical server.
l Initialize the disk: Initialize the disk as instructed on the screen. If the capacity of the new data disk is less than 2 TB, select MBR (master boot record) as the partition form.
Logging in to a Physical Server
1. Logging in to the console
2. Click 
in the upper left corner of the console and select a region. In this topic, Hong Kong 2 is selected.
3. Go to Computing > Physical Server Service to go to the physical server list page.
4. Locate the row that contains the physical server for which the data disk is to be initialized, and in the Operation column, click Remote Login to log in to the physical server. For more information, see Logging in to Windows-based Physical Server.
Initializing Disk (MBR Partition)
1. After successful login, click the Start icon and select Server Manager in the Windows Server area. You will be directed to the Server Manager > Dashboard window.
2. On this page, click Tools in the upper right corner and select Computer Management from the drop-down menu bar.
3. In the left-side navigation pane on the Computer Management page, go to Storage > Disk Management to go to the Disk Management page. On the Disk Management page, if there is a disk that is not initialized, the Initialize Disk window will be displayed automatically, as shown in the following figure:
4. Because the capacity of the uninitialized disk is less than 2 TB, check MBR (Master Boot Record) as the partition form and click OK.
5. Right-click the unallocated capacity area of disk 1 and choose New Simple Volume, as shown in the following figure:
6. In the New Simple Volume Wizard window that appears, click Next as instructed on the screen.
7. You can specify the volume size as required (we recommend that you calculate the capacity of the disk partition before initialization). The default value is the maximum value. Click Next.
8. Check Assign the following drive letter and click Next Page.
9. Check Format this volume with the following settings, set parameters as required, format the new partition. Here, use the defaults. Then, click Next to go to the Finish page.
10. Click Finish and wait for the system to finish the initialization. If the volume status changes to Healthy, the disk is successfully initialized.
