If you add a brand new disk to your PC and it doesn't show up in File Explorer, you might need to add a drive letter, or initialize it before using it. You can only initialize a drive that's not yet formatted. Initializing a disk erases everything on it and prepares it for use by Windows, after which you can format it and then store files on it.

  1. Paragon Hard Disk Manager is an industry-grade Windows disk management and data backup solution that businesses can depend on. Hard Disk Manager is a universal software utility Multi-purpose backup and disk management tool that protects both physical and Hyper-V (Server version only) machines for companies of all sizes.
  2. After launching and MiniTool Partition Wizard, select the system disk as the source disk and choose “Copy Disk” from the menu. Choose a hard disk as the target disk. It is important to know that all data on the target disk will be removed for a successful disk clone.
  3. Disk Management is a system utility in Windows that enables you to perform advanced storage tasks. Here are some of the things Disk Management is good for: To setup a new drive, see Initializing a new drive. To extend a volume into space that's not already part.

Detailed disk space consumption reports. Manage disk space consumption grouped by file type, file size, attributes, file date, and file ownership. Drill down and examine which files are using up your valuable disk space. It's likely that your current hard drive is large enough for your needs if you manage your data storage prudently.


If your disk already has files on it that you care about, don't initialize it - you'll lose all the files. Instead we recommend troubleshooting the disk to see if you can read the files - see A disk's status is Not Initialized or the disk is missing entirely.

To initialize new disks


Here's how to initialize a new disk using Disk Management. If you prefer using PowerShell, use the initialize-disk cmdlet instead.

  1. Open Disk Management with administrator permissions.

    To do so, in the search box on the taskbar, type Disk Management, select and hold (or right-click) Disk Management, then select Run as administrator > Yes. If you can't open it as an administrator, type Computer Management instead, and then go to Storage > Disk Management. Flare 2.

  2. In Disk Management, right-click the disk you want to initialize, and then click Initialize Disk (shown here). If the disk is listed as Offline, first right-click it and select Online.

    Note that some USB drives don't have the option to be initialized, they just get formatted and a drive letter.

  3. In the Initialize Disk dialog box (shown here), check to make sure that the correct disk is selected and then click OK to accept the default partition style. If you need to change the partition style (GPT or MBR) see About partition styles - GPT and MBR.

    The disk status briefly changes to Initializing and then to the Online status. If initializing fails for some reason, see A disk's status is Not Initialized or the disk is missing entirely.

  4. Select and hold (or right-click) the unallocated space on the drive and then select New Simple Volume.

  5. Select Next, specify the size of the volume (you'll likely want to stick with the default, which uses the whole drive), and then select Next.

  6. Specify the drive letter you want to assign to the volume and then select Next.

  7. Specify the file system you want to use (usually NTFS), select Next, and then Finish.

About partition styles - GPT and MBR

Disks can be divided up into multiple chunks called partitions. Each partition - even if you have only one - has to have a partition style - GPT or MBR. Windows uses the partition style to understand how to access the data on the disk.

As fascinating as this probably isn't, the bottom line is that these days, you don't usually have to worry about partition style - Windows automatically uses the appropriate disk type.

Most PCs use the GUID Partition Table (GPT) disk type for hard drives and SSDs. GPT is more robust and allows for volumes bigger than 2 TB. The older Master Boot Record (MBR) disk type is used by 32-bit PCs, older PCs, and removable drives such as memory cards.

To convert a disk from MBR to GPT or vice versa, you first have to delete all volumes from the disk, erasing everything on the disk. For more info, see Convert an MBR disk into a GPT disk, or Convert a GPT disk into an MBR disk.


To create a partition or volume (the two terms are often used interchangeably) on a hard disk, you must be logged in as an administrator, and there must be either unallocated disk space or free space within an extended partition on the hard disk.

If there is no unallocated disk space, you can create some by shrinking an existing partition, deleting a partition, or by using a third-party partitioning program.

    • If you don't want to format the volume right now, select Do not format this volume, and then select Next.

    • To format the volume with the default settings, select Next.

  8. Review your choices, and then select Finish.

Note: When you create new partitions on a basic disk, the first three will be formatted as primary partitions. Beginning with the fourth, each one will be configured as a logical drive within an extended partition.


To format an existing partition (volume)

Warning: Formatting a volume will destroy any data on the partition. Be sure to back up any data you want to save before you begin.

  1. Open Computer Management by selecting the Start button. The select Control Panel > System and Security > Administrative Tools, and then double-click Computer Management.

  2. In the left pane, under Storage, select Disk Management.

How To Use Windows 10 Disk Management

  • You cannot format a disk or partition that is currently in use, including the partition that contains Windows.

  • The Perform a quick format option will create a new file table, but will not fully overwrite or erase the volume. A quick format is much faster than a normal format, which fully erases any existing data on the volume.
