How to Wipe Unallocated Space in Windows 10/8/7 [2 Efficient Ways]
Wiping unallocated space is essential for protecting your privacy and preventing data leakage. To achieve this, you can use one of two efficient methods. First, you can use a disk wiping tool to completely erase the unallocated space, ensuring that any sensitive information is permanently deleted. Alternatively, you can also use a secure deletion tool to overwrite the unallocated space with random data, making it impossible to recover any data that was previously stored there.
Why Wipe Unallocated Space
When you delete a partition, it simply makes the space it occupied unallocated, but the data remains intact. The partition is essentially "unmounted" from the operating system, but the data itself is still present on the disk. This is why data recovery software can often recover data from deleted partitions.
When deleting a partition, the data on the unallocated space cannot be completely erased because of how file system types like NTFS and FAT32 work. When you delete a partition in Windows, the files inside are not completely erased, but rather marked as "deleted" in the master file table, also known as the hard drive index. This is why wiping unallocated space is necessary.
- Protect privacy: To thoroughly clear the data on the partition, you can use the `dd` command in Linux or the `cipher` command in Windows. This will overwrite the data with zeros, making it unrecoverable.
To wipe out unallocated space, you can use the built-in Disk Management feature in Windows or a third-party disk wiping tool. In Disk Management, you can delete the partition on the unallocated space, and then Windows will automatically wipe the space. Alternatively, you can use a third-party tool like DBAN to securely wipe the unallocated space. These methods will ensure that the unallocated space is completely erased and ready for reuse.
Two Efficient Ways to Wipe Unallocated Space
To prevent others from recovering your data, you can wipe unallocated space using either a Windows built-in tool or a third-party tool. Using the Windows built-in tool, such as Disk Cleanup or Disk Management, can be a straightforward process. However, for a more secure and efficient wipe, a third-party tool like DBAN (Darik's Boot and Nuke) can be used. These tools can help you securely erase any remaining data on your device, giving you peace of mind.

Way 2. Use Cipher.exe to Wipe Unallocated Space - Complex
Cipher.exe is a Windows utility that originally encrypted and decrypted files, but also has an "erase" option to securely delete files by overwriting the partition or disk three times.
To wipe unallocated space, you need to create a new partition based on the unallocated space. This involves opening the disk management tool, selecting the unallocated space, and clicking on the "New" button to create a new partition. You can then format the partition to a file system of your choice, such as NTFS or FAT32.
Step 1. Right-click on the Windows icon button and choose "Disk Management."
Step 2. To create a new partition on an unallocated space on your disk, right-click on the space and select "New simple volume." Then, follow the New Simple Volume Wizard to create a new partition with a new drive number or letter.
Step 3. To access the Run dialog box, right-click on the Windows icon and select "Run."
Step 4. Type "cmd," and hit "Enter" to open the command prompt. Then, type "cipher /w:c" and hit "Enter" to create a new drive letter, replacing C with the desired letter.
The "/w" command in the Diskpart utility overwrites all unallocated space on the hard drive three times, taking some time depending on the amount of data on the partition. This process is also known as the "Wipe" function. It is used to securely erase data on a partition by overwriting it three times, making it difficult to recover.
- First time - 0x00
- Second time - 0xFF
- Third time - random numbers
