by John, Updated on: August 24, 2022

Storage device is an indispensable component to a server, no matter you use SSD, mechanical HDD or hardware RAID array. To initialize disk, create, move and resize partitions, you need a reliable disk management tool. Windows Server 2008 (R2) has a native "Disk Management" tool. It can do some basic operations such as create, delete and format partition. Better than previous version, it can shrink and extend partition, but the ability is limited. Disk partition software has more functions, but you'd better run the safest program.

1. How to open Disk Management in Server 2008 (R2)

There are 2 common ways to open Disk Management in Windows Server 2008 and R2:

  1. Press Windows + R together on the keyboard, type diskmgmt.msc and press Enter.
  2. Click Server Manager on bottom left of the screen behind Windows logo, and then switch to Storage > Disk Management.

2. Basic features of Windows Server 2008 Disk Management

After opening Disk Management, right click a partition or the front of a disk, then you'll see the available operations:

Partition operations

Disk operations

To a brand new hard disk:

Create new volumes.

To an allocated partition:

  • Open root directory in File Explorer
  • Mark partition as Active

  • Format partition
  • Delete partition

3. Advanced features of Windows Server 2008 Disk Management

Manage dynamic volumes:

It is able to create and manage Simple, Mirrored, Stripped, Spanned and RAID 5 dynamic volume.

Dynamic disk volumes consume much resources and decrease server performance. Because hardware price is much cheaper now, most of servers use hardware RAID arrays instead of dynamic volume.

Disk conversion:

Disk Management has the option to convert disk between MBR and GPT, but you must delete all partitions on the disk in advance.

It can only convert Basic disk to Dynamic without losing data. To convert Dynamic disk to Basic, you must delete all partitions on the disk, too.

Change partition size:

Better than previous version, Server 2008 Disk Management has new Shrink and Extend Volume feature to help resize partition without losing data.

Comparing with other advanced features, these new functions are likely to be used. However, you cannot extend a partition by shrinking another one.
