At times, you need to find out the disk space in total (including used space & free space) on your computer HDD or SSD. The common way for us to access a hard drive to check information is via Windows Explorer. It's easy but not accurate to check a total hard drive capacity on a hard drive on which a single partition is created. One partition size equals one hard disk size, however, not for the case that there is unallocated space available except the one partition/volume, because Windows Explorer won't display the amount taking by unallocated space.

In addition, when there are multiple partitions or volumes on a hard disk, there is no way for you to check its total size in Windows Explorer unless you calculate the result by yourself. So, how to check the total hard drive size in Windows 10, 8.1, 8, or 7 in a visible way without calculation? We gathered three ways for you.

Way 1. EaseUS Partition Master - Check Total Hard Drive Size with 100% Accuracy [Free]

With a third-party free partition manager running exclusively on Windows platforms - users can clearly notice significant parameters and elements on a hard disk, let it be an internal HDD/SSD or an external hard drive or removable flash drive, including how much disk space in total and how much used space and free space has left. If there is unallocated space without assigning a file system and drive letter at the moment, you can also see how large it is very clearly on EaseUS Partition Master's interface.

Step 1. Download and install EaseUS Partition Master Free on your Windows PC.

Step 2. If it's to check an external storage drive's disk space, make sure that it has been correctly connected to Windows. Open EaseUS Partition Master, you can check the total disk space size in any disk in two sections:

All in all, in EaseUS Partition Master, you can get to know how large your hard drive is, and how much disk space you've used and how much disk space you have left.

Way 2. Windows Disk Management - Display Total Hard Drive Size but Nothing Else

A small group of Windows users says that they can check a total hard drive's capacity in Windows Disk Management, which is the other attainable solution. Compared with the all-around third-party disk space check viewer, though not displaying in a visualized picture, Windows Disk Management can present the core part of what you want to know about a hard drive's space.

Step 1. Press Windows + R keys to evoke Run, type diskmgmt.msc and hit Enter.

Way 3. Windows Command Prompt - Require Administrator's Privilege

Windows advanced users tend to operate in a background program called Windows Command Prompt, where you can apply a variety of command lines to troubleshoot very common computer issues, most of which require administrator's privilege to get started. Therefore, if you have some computer skills, and have a good command of basic command lines, you can use the following command to check the total hard drive size for a specific hard drive.

Step 1. Search command prompt in Windows 10, and right-click on the result and choose Run as administrator.

Step 2. Type wmic diskdrive get size and press Enter. Finally, the total size of hard disk space (in pure number) is displayed in the figure below.

* For average users who are unable to calculate the returned number to GBs, the information displayed by the command prompt will be undoubtedly complicated to understand. Thus, this command prompt method to check total hard drive size is only recommended to advanced users.

Which Way Do You Prefer to Check Total Hard Drive Size in Windows?

Regarding the topic "how to check total hard drive size", "how do I find out my hard drive storage size" or "how big is my hard drive", we gathered three ways for you to follow. According to the detailed description of each section of the recommended tool, you should know that all the three ways are free to use, and all are able to display the total hard drive storage size clearly, but in different forms.

  • EaseUS Partition Master displays the most information related to a hard drive, with a visualized form. 
  • Windows Disk Management presents nothing but only the hard drive space in total.
  • Windows Command Prompt lists the hard drive space using a giant number, not in GBs or TBs very clearly.
