Causes of Hard Drive Shows Half or Partial Capacity
Hard Drive, like HDD/SSD, plays an essential role in reading and writing data. The bigger the hard drive, the better. So we don't need to worry that there is a low disk space warning when keep installing programs, and games or saving huge documents, movies, music, and whatever we want in daily computer use.
However, many people found that they invest in a large hard drive of 1TB, 2TB, and 4TB, but only see half capacity, or even partial capacity available for usage. What's the problem? Why is the hard drive not showing its correct size?
In general, the hard drive showing wrong size issue happens to a lot of users, and the following reasons may account for the problem:
- Virus or malware infection
- The hard drive, SSD, or external hard drive is with MBR style
- Files invisible
- Partition deleted or lost, showing unallocated

Video Tutorial of Restoring Data from External HDD
Step 1. Select and scan the lost partition
Launch EaseUS Data Recovery Wizard, select "Lost Partition" and click "Scan" to search for all the lost data. If there are many lost partitions, you can identify them through its partition size.
Note: Since the Windows system doesn't support the Linux file system, the Ext2 or Ext3 partition will be recognized as lost partition with no drive letter in the software. If you want to recover data from Ext2/Ext3 partition, you can follow these steps.
Step 2. Filter the scanned results
Because there will be a lot of scanned files, you can choose a file category for quick filtering, such as Pictures, Videos, Documents, Audio, and Others. Or if you remember the file name, you can just look it up in the search box in the upper right corner.
Step 3. Preview and recover data from the lost partition
Before recovery, you can preview the file to make sure it is the data you need. Choose all the files you need and click "Recover" to restore them.
6 Fixes to Reclaim Full Size of Hard Drive That Shows Only Half or Partial Capacity
After knowing the reasons, you can feel released for a while because we're going to share corresponding solutions with you.
Method 1. Remove Virus That Makes Hard Disk Showing Wrong Size
Applies to: Fix HDD/SSD, or external hard drive not showing full capacity due to virus infection.
When your hard drive is infected with virus or malware which eats some storage space on your hard drive, it only shows half or patial capacity. You can perform antivirus software to keep your drive clean and safe.
Step 1. To check virus or malware infection
If you have anti-virus software installed, run the anti-virus software for the first time. If you don't have anti-virus software, try Avast, AVG, etc., and download and install one on your PC.
Step 2. Keep your problematic HDD, SSD, or external hard drive connected to the PC correctly.
Step 3. Run antivirus software to scan your device and clear up the existing virus, or malware.
For people who don't have the software, you can also refer to this linked page and learn how to use cmd to remove viruses in Windows 10/8.1/8/7.
Method 2. Convert MBR to GPT to Restore Full Capacity of Large HDD/SSD
Applies to: Fix large hard drive, SSD, or external hard drive only shows half or partial capacity due to MBR limitation.
Another reason that may stop your disk from showing full capacity is due to the limit of the MBR partition style. As we know, MBR only works with disks up to 2TB in size, at the same time, allowing for creating 4 partitions in total.
If you have a particularly large-capacity hard drive that is over 2TB but initialized to MBR style, you will only get 2TB storage capacity in total. To make full use of the rest space you don't see, you need to convert MBR to GPT.
EaseUS Partition Master is a perfect choice to convert hard disks between MBR and GPT, it's super easy and guaranteed zero data loss during the conversion.
Step 1. Download and launch EaseUS Partition Master on your Windows computer.
Step 2. Right-click the MBR disk that you want to convert and choose "Convert to GPT".
Step 3. After that, find and click the "Execute 1 Operation" button on the toolbar and choose "Apply" to start the conversion.
Once the MBR to GPT conversion process completes, you will get the full size of your HDD, SSD, or external hard drive again.
Method 3. Create New Volume to Make Use of Unallocated Space on Disk
Applies to: Make use of unallocated space on hard drive or SSD which only shows half or partial space.
Sometimes, the hard drive shows half capacity because the other half-space is unallocated. You can create new simple volumes on the disk to make full use of the other half or partial unused space:
Step 1. In Windows 10/8.1/8/7, press Windows + R hotkeys to bring up the Run box, type diskmgmt.msc and hit Enter.
Step 2. On the disk map, check if the hard drive partition displays as Unallocated.
If yes, you can create a new simple volume on the unallocated space with the continuing steps.
Step 3. Right-click on the unallocated space and select "New Simple Volume".
Step 4. Set a new drive letter, file system and size for the new volume.
Step 5. Follow the onscreen instruction guidelines to finish the process.
If you need to create more partitions with the unallocated space, repeat the process until you've used all unallocated space on the target disk. After this, you will be able to see the full capacity and make full use of the disk space again.
Method 4. Show Hidden Partition That Makes Disk Showing Wrong Size
Applies to: Fix hard drive or SSD showing the wrong capacity on Windows 10/8/7 due to hidden partition.
When the other half-space of your disk is hidden somewhere or you hide some partitions with partial space on your computer disk, you may not be able to see its full capacity in Windows File Explorer.
The way to fix this issue is to unhide or show the hidden partition on a computer with the following steps:
Step 1. Keep your target disk connected to the PC correctly and open Disk Management.
Step 2. Right-click the partition named New Volume which has no drive letter and select "Change Drive Letter and Paths for New Volume".
Step 3. Click "Add" to assign a new drive letter for the partition to make visible in Windows File Explorer.
- For example, you can assign the drive letter F for the hidden partition and click "OK".
After this, you can restart the PC and when you reopen File Explorer, you will be able to view and access to other half or partially hidden partitions of your disk.
Method 5. Add Unallocated Space to A Neighbor or Non-adjacent Partition
Applies to: Make full use of unallocated space on the hard drive, or external hard drive by adding unallocated space to a neighbor or non-adjacent partition.
When there is unused space on your disk or external hard drive, you may also not be able to see its full capacity on the computer. Only half or partial space is visible.
In this case, you can either try to create new simple volumes as recommended in Method 3 or try the tips below to add unallocated space to other existing partitions that are adjacent or non-adjacent.
#1. Add Unallocated Space to A Neighbor Partition
If the unallocated space is behind an existing partition, you can add the unallocated space to extend the neighbor partition using Disk Management:
Step 1. Open Disk Management on your computer and locate the unallocated space.
Step 2. Right-click on the neighbor partition that you want to extend, and choose "Extend Volume" to continue.
Step 3. Set and add more size to your target partition and click "Next" to continue.
Step 4. Click "Finish" to complete the process.
#2. Add Unallocated Space to Non-adjacent Partition
If you want to add the unallocated space to a non-adjacent partition, you can apply EaseUS Partition Master with its Resize/Move feature for help.
It allows you to freely move unallocated space next to a target partition and extend it with ease:
Step 1. Locate the Target Partition
To start extending partition, you should first locate the target partition and select "Resize/Move".
Step 2. Extend the Target Partition
Drag the partition panel rightward or leftward to add unallocated space into your current partition and click "OK" to confirm.
Extra Option: Get Space from Another Drive
If there is not enough unallocated space on your disk, right-click on a big partition with enough free space, select "Allocate space".
Then select the target partition that you want to extend at the allocate space to column.
Step 3. Execute Operations to Extend Partition.
Drag the dots of the target partition into the unallocated space and click "OK".
Then Click the "Execute Operation" button and click "Apply" to keep all the changes.
Method 6. Perform Partition Recovery and Restore Full Disk Capacity
Applies to: Fix hard drive, SSD shows only partial space as partition gets deleted or lost.
