As we all know, Windows Server Manager is a management console tool used by IT professionals to facilitate the provisioning and administration of local and distant Windows-based servers from their desktop computers. This console eliminates the need for physical server access and the requirement to enable distant Desktop protocol (rdP) connections to each server.

However, to ensure your Windows Server runs smoothly and keeps all tasks performing well, there is another resource you need to pay attention to: your hard disks on Windows Server computer.

So, in this post, we’ll show you how to manage your hard disk and give you some advice on how to use Windows Server disk manager for your machine.

Why do you need a Windows Server manager for disk and partition?

• Data Integrity
First, hard disks store critical data for the server and its users. If a disk fails or becomes corrupted, it can lead to data loss, which can have severe consequences for the organization.

• System Performance
A healthy hard disk is essential for optimal system performance. If a disk develops bad sectors or other issues, it can slow down read and write operations, leading to sluggish performance for applications and services running on the server. So, monitoring the disk's health allows administrators to identify and address performance issues proactively.

• Preventing disk failing
In addition, hard disk failures can result in unexpected downtime, disrupting business operations and causing productivity losses. By monitoring disk health, administrators can anticipate potential failures and take preemptive measures, such as replacing failing disks or migrating data to redundant storage solutions, to minimize downtime and maintain service availability.

Basic Windows Server disk management

In fact, some basic Server disk managements you need can be satisfied by system tool. Windows Disk Management is a built-in utility in Windows Server that allows users to manage storage devices such as hard drives, solid-state drives (SSDs), and external storage devices. It provides several key functionalities:

▶ Partition Management
Disk Management enables users to create, delete, format, and resize partitions on their storage devices. This allows for efficient organization and allocation of disk space.

▶ Disk Initialization
Users can use Disk Management to initialize newly installed disks, preparing them for use with the server. This process involves selecting the disk type (MBR or GPT) and creating a partition table on the disk.

▶ Volume Management
Disk Management facilitates the creation and management of volumes, which are logical storage units within partitions. Users can assign drive letters, mount points, and file systems to volumes, making them accessible to the operating system and applications.

▶ Disk Maintenance
Disk Management provides tools for disk maintenance tasks such as marking partitions as active, changing drive letters, and converting disk types between basic and dynamic.

▶ Disk Properties
Users can view detailed information about their storage devices, including disk capacity, free space, partition layout, and disk status.


How do I access Disk Management on Windows Server?

1. You can access Disk Management via pressing Windows + R to open Run, type “diskmgmt.msc” in the box and press Enter.

2. Go to ”Control Panel” > ”System and Security” > ”Administrative Tools” > ”Create and format disk partitions”.

3. Right-click the Start menu and select Server Manager. In the Server Manager interface, choose Computer Management under Tools tab.

4. Press the Win + X keys on your keyboard and then tap on the Computer Management shortcut from the given menu to open Computer Management. Click Disk Management under Storage on the left side of the Computer Management window.

Advanced Windows Server manager for disk and partition

Once you've used Windows Disk Management to modify your disks and manage your partitions and drives, you'll see that it has a lot of limits, which are also evident concerns. If you're trying to expand C drive and encounter the "Extend Volume" option being greyed out, it might be because there isn't any free space on the disk. To convert a disk to GPT, you'll have to remove all data and partitions from the target drive. Furthermore, there is no way to clone a drive for a speedy update or to transfer software to free up space without risking data loss.

Therefore, it is thoughtful to choose AOMEI Partition Assistant Server, a superior server disk management application, to circumvent all restrictions of Windows Disk Management. AOMEI Partition Assistant Server is compatible with Server 2022, 2019, 2016, 2012, 2008, and 2003, which simplifies duties and compensates for the shortcomings of the Server snap-in Disk Management utility.
