Causes of Hard Drive Shows Half or Partial Capacity

A hard drive, whether it's a traditional HDD or a newer SSD, is crucial for reading and writing data. The bigger the hard drive, the less likely you are to encounter low disk space warnings, allowing you to install programs, games, and save large files, documents, movies, and music without worrying about running out of space.

The issue of a hard drive not showing its correct size, often referred to as a "capacity discrepancy," is a common problem that can be frustrating for users. This issue can occur due to various reasons, such as incorrect formatting, partitioning errors, or issues with the hard drive's firmware. In some cases, the hard drive may be showing only half its capacity because it's being used as a secondary drive, and the primary drive is taking up the remaining space. To resolve this issue, users can try reformatting the hard drive, checking for any disk errors, or using a disk management tool to re-partition the drive.

The hard drive showing wrong size issue can occur due to various reasons, including incorrect partition table information, corrupted file system, or outdated disk management software. This can lead to discrepancies between the actual and reported hard drive sizes, causing frustration for users.

• Virus or malware infection
• The hard drive, SSD, or external hard drive is using Master Boot Record (MBR) style.
• Files invisible
• Partition deleted or lost, showing unallocated

6 Fixes to Reclaim Full Size of Hard Drive That Shows Only Half or Partial Capacity

Now that you know the reasons behind the issue, you can feel a sense of relief as we're about to share the corresponding solutions with you.

Method 1. Remove Virus That Makes Hard Disk Showing Wrong Size

A virus infection can cause a hard drive or solid-state drive to not show its full capacity, making it appear smaller than it actually is. To fix this issue, you can try using a virus removal tool or a disk cleanup software to remove any malicious programs that may be taking up space on the drive.

If your hard drive is infected with a virus or malware, it can consume storage space, making it appear as though your drive has only half or partial capacity. To resolve this issue, running antivirus software can help keep your drive clean and safe, freeing up storage space and restoring your hard drive to its full capacity.

Step 1. To check virus or malware infection

If you have anti-Install anti-virus software on your PC, then run it for the first time. If you don't have one, download and install Avast or AVG.

Step 2. To keep your problematic HDD, SSD, or external hard drive connected to your PC correctly, ensure that the drive is securely fastened to the PC case using screws, and the power cable is properly connected to a working power source.

Step 3. Run antivirus software to scan your device and clear up the existing virus, malware.

For those without the necessary software, an alternative solution is to refer to a linked page that provides instructions on how to use the Command Prompt (cmd) to remove a virus in Windows 10, 8.1, 8, or 7.

Method 2. Convert MBR to GPT to Restore Full Capcity of Large HDD/SSD

To fix a large hard drive, SSD, or external hard drive that only shows half or partial capacity due to MBR limitation, you can use a tool to convert the MBR to GPT, which allows larger drive sizes. This process involves backing up your data, booting from a live USB or CD, and using a command-line tool like `gdisk` or `fdisk` to convert the drive's partition table.

The disk may not show its full capacity due to the limitations of the Master Boot Record (MBR) partition style. MBR is only compatible with disks up to 2TB in size and allows for a maximum of 4 partitions, which can restrict the total storage capacity.

If you have a large-capacity hard drive that's over 2TB and initialized to MBR, you'll only be able to use 2TB of it. To make the most of the unused space, you need to convert it to GPT.

Qiling Partition Master is a tool that allows users to convert their hard drive between MBR (Master Boot Record) and GPT (GUID Partition Table) formats without losing any data. This process is easy and reliable.

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

Step 2. To convert an MBR disk to GPT, click on the disk you want to convert, click "More" and select "Convert to GPT".

Once the MBR to GPT conversion process completes, your HDD, SSD, or external hard drive will regain its full size.

Method 3. Create New Volume to Make Use of Unallocted Space on Disk

Applies to: Make use of unallocated space If your computer's hard drive or solid-state drive (SSD) is showing only half or partial space, it's likely due to a formatting issue or a problem with the drive's partitioning. This can be caused by a software glitch, a power outage during a write operation, or a faulty drive.

The hard drive showing half capacity is likely due to unallocated space on the other half, which can be utilized by creating new simple volumes on the disk. This allows for the full use of the unused space, effectively making the entire hard drive capacity available.

Step 1. To open the Disk Management tool in Windows, press the Windows key + R to open the Run dialog box, type "diskmgmt.msc" and press Enter. This will open the Disk Management tool, where you can view and manage your disk drives.

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 the unallocated space on the target disk. This will allow you to utilize the full capacity of the disk again.

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

If your hard drive or solid state drive (SSD) is showing the wrong capacity on Windows 10, 8, or 7, it could be due to a hidden partition. To fix this issue, you can try running the built-in Disk Cleanup tool, checking for and removing any unnecessary system files, and checking the disk for errors.

When part of your disk space is hidden or partitioned, Windows File Explorer may not display the full disk capacity.

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 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 restarting your PC, when you reopen File Explorer, you'll be able to view and access the previously hidden partitions on your disk.

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

This feature allows you to make full use of unallocated space on a hard drive or external hard drive by adding it to a neighboring or non-adjacent partition, effectively utilizing the unused space.

When there is unused space on your disk or external hard drive, you may not see its full capacity on your computer, instead 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 located behind an existing partition, you can use Disk Management to add the unallocated space to the neighbor partition, effectively extending its size.

Step 1. To free up space on your computer, open the Disk Management tool, which is usually found in the Control Panel or by typing "diskmgmt.msc" in the Run dialog box.

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

Step 3.The target partition is resized to fit the new size, and the process continues with the next step.

Step 4. Click "Finish" to complete the process.

#2. Add Unallocated Space to Non-adjacent Partition

If you want to add unallocated space to a non-adjacent partition, you can use Qiling Partition Master's Resize/Move feature to help with the process.

You can easily expand a partition by moving the unallocated space next to it, making the process simple and efficient.

Method 6. Perform Partition Recovery and Restore Full Disk Capacity

To fix a hard drive or SSD that only shows partial space as a partition gets deleted or lost, you can try using a data recovery software to scan the drive and recover any lost partitions. Additionally, you can use a disk management tool to check for any issues with the drive's partition table and attempt to rebuild or reassign the drive letters.

When some partitions on your disk get deleted or lost, it can lead to a situation where you only see a partial storage space on your Windows PC, rather than the full capacity of the disk.

To recover full capacity and data on your disk without losing any information, you can either use Deep Data Recovery to restore data and create new partitions on the unallocated space, or run a reliable partition recovery software to bring back all lost, deleted, even hidden partitions with data.

Qiling Partition Recovery can recover lost, deleted, or hidden partitions and their data, making it seem like the partition was never lost.

Conclusion

When a hard drive, SSD, or external hard drive shows only half or partial capacity on your computer, it's often due to a compatibility issue or a formatting problem. This can occur when the drive is not recognized by the operating system or when the drive's file system is not compatible with the host system. In some cases, the drive may have been formatted with a different file system, such as exFAT, which is not recognized by the host system, resulting in a partial capacity display. To resolve this issue, you can try reformatting the drive with a compatible file system, such as NTFS, or using a different USB port or interface.

You can use data recovery software like EasUS Data Recovery Wizard to scan and restore data from the invisible partial space, then apply various methods to recover or restore your partial space on the disk, such as clearing up viruses, converting the disk from MBR to GPT, recovering deleted partitions, showing hidden partitions, creating a new volume on unallocated space, or adding unallocated space to existing partitions.

To maximize your disk space, it's essential to regularly back up your valuable data and run virus cleaner software to keep your device clean and safe. This ensures that your important files are secure and your device is free from malware.
