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 low disk space warning when keep installing programs, 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, 4TB, but only seeing 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:

Recover Data First Before Fixing HDD Shows Half Capacity Issue

Applies to: Scan and restore all existing available data on the hard drive, SSD, or external hard drive which shows half or only partial space in Windows PC.

If you have saved valuable data on the hard drive, SSD, or external hard drive that only has half or partial space visible, you should first take action to scan and restore all valuable data to another secure device first. If you have files to recover, download and install Deep Data Recovery.

It's hard disk data recovery software that specializes to recover data after deleting, formatting, or virus infection from all types of storage devices regardless of their capacity show only half, partial, or full:

Step-by-Step Guide:

Step 1. Select file types and click "Next" to start

Launch Deep Data Recovery, select file types and click "Next" to start.

Select file types that you want to recover

Step 2. Select and scan the lost partition

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.

select a location and click scan

Step 3. 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 4. 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 an anti-virus software, try Avast, AVG, etc., download and install one on your PC.

Step 2. Keep your problematic HDD, SSD, or external hard drive connected to PC correctly.

Step 3. Run antivirus software to scan your device and clear up the existing virus, 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 virus in Windows 10/8.1/8/7.

Method 2. Convert MBR to GPT to Restore Full Capcity 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 capcity is due to the limit of MBR partition style. As we know, MBR only works with disks up to 2TB in size, at the same time, allows 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.

Qiling Partition Master is a perfect choice to convert hard disk between MBR and GPT, it's super easy and guaranteed with zero data loss during the conversion.

Step 1. Download and launch Qiling Partition Master on your Windows computer.

Step 2. Click the MBR disk that you want to convert, click "More..." button and choose "Convert to GPT" to start the conversion.

Once the MBR to GPT conversioni 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 Unallocted 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 showing half capacity is 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".

Create new simple volume on unallocated space of hard disk.

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.

Finish creating new volumes on unallocated space of hard disk

If you need to create more partitions with the unallocated space, repeate the process untile 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 sapce again.

Method 4. Show Hidden Partition That Makes Disk Showsing Wrong Size

Applies to: Fix hard drive or ssd showing wrong capacity on Windows 10/8/7 due to hidden partition.

When 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 hidden partition on computer with the following steps:

Step 1. Keep your target disk is connected to PC correctly and open Disk Management.

Step 2. Right-click the partition named as New Volume which as 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.

Unhide partition.

Find hidden partition in Windows 10/8/7.

After this, you can restart PC and when you reopen File Explorer, you will be able to view and access to other half or partial hidden partitions of your disk.

Method 5. Add Unallocated Space to A Neighbor or Non-adjacent Partition

Applies to: Make full use of unallocated sapce on 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 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 to 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 unallocted space.

Step 2. Right-click on the neighbor partition that you want to extend, and choose "Extend Volume" to continue.
