disk-not-initialized

In general, you cannot see the uninitialized disk in File Explorer, as it does not have a file system, but in Disk Management, shown as unallocated space or no capacity.

It does not mean your data is gone. They are still on the disk and recoverable (if there's no data overwriting). We'll show you 3 useful methods to recover data from initialized disk.

Why is the disk shown as uninitialized?

This "disk unknown not initialized" issue can be caused by many reasons. Here are some common reasons:

  • You get a brand new HDD or SSD without initializing.
  • You initialize a disk incorrectly.
  • Windows can't recognize the disk well due to corrupted partition table.
  • Physical damage, such as bad sectors, or hardware failure can cause uninitialized disks.
  • Viruses or malware attack your partition table or file system, causing initialized disks.

How to recover data from uninitialized disk

Now, you may be wondering how to recover data from uninitialized disk. There are many methods, but the most effective method is to use reliable data recovery software. The process is divided into two parts, the first of which is initializing the disk to make it easier to be recognized.

Part 1: Initialize Disk showing "Uninitialized"

We will show you how to initialize disk in Disk Management.

⚠️The disk initialization is a process of creating the partition table using MBR (Master Boot Record) or GPT (GUID Partition Table). It will not erase data unless you continue to create individual partitions or format it to store data or for other usages.  

Step 1. Open Disk Management

Press “Win + X” and select the “Disk Management” option.

Step 2. Select "Initialize Disk"

In Disk Management, locate and right-click the uninitialized disk and select the “Initialize Disk” option.

Step 3. Pick a Partition Style

Choose “MBR” or “GPT” as you prefer. To some degree, GPT is a better choice. Then click “OK” to save these changes.
