7 Methods to Fix Disk Unknown Not Initialized Problem

Are you struggling to access your files due to the “disk 1 unknown not initialized” error? This issue can impact both internal and external drives. When you encounter the “disk management unknown not initialized” error, it raises concerns about fixing the problem and potential data loss resulting from it.

But fret not. This article explores six easy methods to recover data from an uninitialized disk. We’ll also provide a practical approach to retrieving lost data from such disks and offer tips to prevent this error in the future. So, let’s get on with it!

Part 1. Overview of the ‘Disk Unknown Not Initialized’ Error

1.1 What Does ‘Disk Unknown Not Initialized’ Mean?

The “disk unknown not initialized” error happens when the operating system detects a disk but it hasn’t been set up for use. Essentially, the disk lacks a valid signature, meaning it hasn’t been appropriately registered with the system.

Registration occurs when you format the disk at least once. When the “hard drive unknown not initialized” happens, your external hard drive may display “unallocated space” or no information about its capacity in Disk Management. Consequently, you can’t open or access the data on the disk.

1.2 Common Reasons Behind Disk 1 Unknown Not Initialized

The ‘disk not initialized Windows 10’ error may occur due to different reasons, such as the following:

  • If the Master Boot Record (MBR) is corrupted, the operating system can’t access data on the hard drive.
  • Bad sectors on the external hard drive may also cause the error.
  • Using an outdated driver might lead to the “hard drive unknown, not initialized” issue in Windows Disk Management.
  • A virus attack could also be a reason for an external hard drive showing as unknown or not initialized.
  • A lost or deleted partition on your hard disk might be the cause of the “disk not initialized Windows 10” error.

  • Retrieves files from crashed systems and formatted drives.

Here’s how to use this tool to recover lost data from an uninitialized disk:

Step 1: Get the tool, install and launch it on your computer. If you’re using an external disk, the tool will detect it. Choose the disk with inaccessible data or select target file types to recover in the upper-right corner before scanning. Click “Start.”

Step 2: The tool will scan the chosen drive for missing data, allowing you to pause or stop the search anytime you find the files you need. Preview categories like Deleted Files or Lost Location under the Tree View. You can also switch to File View to check for file types like video, documents, etc. Use the Filter for a focused search.

Step 3: Once you’ve recovered your target files, preview and recover them to a safe location.

2.2 Perform Basic Checks

A bad drive connection, poor USB port condition, or a damaged cable may cause the “disk unknown not initialized” error if you’re using an external drive. Begin by unplugging and re-plugging the hard drive into your computer. Then, connect the external hard drive to a different USB port using the original cable.

Alternatively, use a different cable to connect the external hard disk. Another option is to connect the external hard drive to another computer. All of these checks are to rule out any temporary connection, USB cable, or port problems.

2.3 Update Device Driver

If your drive isn’t facing connection problems, an outdated disk driver could be behind the “disk 1 unknown not initialized” error . To fix it, update your disk drive drivers. Here’s how:

Step 1: Head to “This PC,” right-click on it, choose “Manage,” and then navigate to “Device Manager.”

Step 2: Expand “Disk drives,” find and right-click the problematic disk, and pick “Update driver.”

Step 3: Opt for “Search automatically for drivers” and let Windows update the driver. Or you can download the specific driver and choose “Browse my computer for drivers” to install it manually.

Step 4: Afterward, restart your system and check if the external drive shows up as disk unknown, not initialized, unallocated.

Part 3.  5 Solutions to Fix Disk Unknown Not Initialized Easily

Once you’ve recovered data from the uninitialized disk and performed basic checks, go ahead and fix the “disk management unknown not initialized” issue without concerns about data loss. Here are four solutions to try:

3.1 Initialize the Unknown Disk

In case the previous methods don’t fix the ”disk management unknown not initialized” issue, initialize the disk using MBR or GPT. Opt for MBR if you plan to use the drive across an older Windows version. GPT isn’t compatible with Windows versions older than 10. Here’s how to initialize the unknown disk in Disk Management:
