Your situation will have different solutions to the problem "disk not initialized" on your computer.
Solution 1. Initialize the WD HDD or External Hard Drive
Applies to: Disk not initialized and shows unallocated space
The very first thing you need to do is initialize your hard drive or external devices. It is the quickest and easiest way to fix disk 1 unknown, not initialized error. You can use Disk Management to initialize the disk or use a tool. The easy-to-use partition manager software - Qiling Partition Master is my recommendation. This software is fully compatible with all Windows systems, and you can directly follow to fix WD HDD/external hard drive not initialized error now.
Step 1. Open Qiling Partition Master. Connect the hard drive or SSD to PC.
Click the target HDD or SSD and select "Initialize to MBR" or "Initialize to GPT" accordingly.
Solution 2. Fix Disk Unknown by Creating a New Partition

Another way to solve the WD disk unknown or not initialized error is by creating a new partition. You can create a new partition with Qiling Partition Master or with Disk Management. Here are the steps to create a new partition with Disk Management:
Step 1. Right-click "This PC" and choose "Manage" > "Disk Management".
Step 2. Right-click the unallocated space and choose "New Simple Volume..."
Step 3. In New Simple Volume Wizard, click "Next" to continue.
Step 4. Follow the wizard to specify the volume size, assign a drive letter to the volume, and format the partition to the wanted file system.
Solution 3. Fix WD Not Initialized by Recovering Partition
Applies to: Disk not initialized and shows unallocated space
In Disk Management, if you find disk shows unallocated space, just try to make partition recovery. To make it, you need an effective partition recovery software - Qiling Partition Master. As I have mentioned in Solution 1, this software can not only initialize the disk but also recover lost partition.
Steps to recover lost partition:
Step 1. Connect the external storage device to your computer for lost partition recovery. To begin with, click "Partition Recovery" on the top menu. Then choose the target disk and click "Scan".
Step 2. Qiling Partition Master will scan and display all the partitions that are existing and lost under the selected disk. You can choose the partition that clearly shows as "Lost" in the "Status" tab and click "Proceed".
Double-click on a partition will allow you to preview the content.
Step 3. Click "Recover" as along as all the lost data has been found. If not, go on with the "Continue Scanning" option.
Step 4. Wait the software processing the final recovery. Your lost partition should reappear in the drive.
If Disk Management can't show any information on neither this hard drive nor its disk capacity, the hard drive might be blocked by the "external hard disk not initialized I/O" error. Then, you should follow the solutions below.

If you are faced with this error, you should check the connection as soon as possible. The connection issue can cause serious problems. To check the connection:
