Updated on: November 16, 2019

This article explains what Windows 7 Disk Management is, ability and disadvantages of this native disk partition management tool.

Hard disk drive is a vital component to a computer, your precious files such as family photos, videos, work documents are saved in the hard disk, no matter it is internal or removable. Unlike Mac computer, partitions in Windows are very likely running out of space. A powerful and reliable disk partition management tool is very important to all Windows laptop, desktop and servers. Windows 7 has built-in Disk Management, is it the right tool?

What is Windows 7 Disk Management

Disk Management is a Microsoft Windows utility first introduced in Windows XP as a replacement for the fdisk command. It enables users to view and manage the disk drives installed in their computer and the partitions associated with those drives.

Disk Management can manage the storage that can be recognized by Windows, for example: hard disk drive (internal and external), optical disk, flash drive and hardware RAID array.

How to open Disk Management in Windows 7:

Press Windows and R together on the keyboard, type diskmgmt.msc and press Enter.

By default, you'll see all single partitions on the top with the information such as Layout, Type, File System, Status, Capacity, Free Space. On the bottom, you'll see all disk with partition structure.

What does Windows 7 Disk Management do

To a brand new hard disk:

  • Online, offline
  • Initialize.

Hard disk must be online and initialized before creating new volume.

To Unallocated space:

Create new volumes.

To an allocated partition:

  • Open root directory in File Explorer
  • Mark partition as Active
  • Change drive letter and path
  • Format partition
  • Delete partition

Manage dynamic volumes:

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

Dynamic disk volumes consume much server resources. Hardware price is much cheaper now, so 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, convert disk between Basic and Dynamic (destructively).

However, it can only convert Basic disk to Dynamic without losing data. To convert Dynamic disk to Basic or convert between MBR and GPT, you must delete all partitions in a disk.

Change partition size:

Better than previous version, Windows 7 Disk Management has new Shrink Volume and Extend Volume feature to resize allocated partition without losing data.

However, only NTFS partitions are supported, in addition, Disk Management cannot expand a partition by shrinking other one.

Shortages while resizing partition with Disk Management

As I said before, the disk partitions in Windows computer are very likely running out of space, especially to system C drive, so many people need to resize and extend system partition. With Disk Management, you can only:

Extend Volume disabled

As the screen shot shows, Extend Volume greyed out for both C: and E: drive after shrinking D. This is because:

  • Shrink Volume function can only make Unallocated space on the right side while shrinking partition.
  • Extend Volume function can only combine Unallocated space to the contiguous partition on the left.

Drive C is non-adjacent and E is on the right of the Unallocated space, therefore, Extend Volume function is disabled.
