When using the Windows Disk Management Utility, you may have come across an instruction that reads thus, "You must initialize a disk before Logical Disk Manager can access it." This notice sounds urgent but you have no idea of whether it's safe to initialize a disk, and whether initializing a disk would erase data. 

This post will help you figure out why Logical Disk Manager insists that you initialize a disk, what happens to your data when you initialize a disk, and most importantly, how to recover lost data during disk initialization or formatting.

Part 1. Why Disk Manager Insists that You Initialize a Disk

One of these common hard disk issues could have caused Disk Manager to insist that you initialize your hard disk.

  • The hard drive is new and has never been connected to the computer.

  • Windows fails to find a valid partitioning table in the hard drive.

  • Your hard drive is faulty, damaged, or corrupt.

  • The hard drive has a non-standard partitioning configuration, which causes migration between different storage controllers.

  • Other issues and errors in the removable hard disk.

Part 2. Does Initializing a Disk Erase Data?

A short answer is NO. Only initializing a disk won't erase data.

The initialization aims to rebuild MBR, involving no data. But to make the disk usable again, you need to further partition and format the drive, which will definitely erase data. Therefore you should distinguish the two actions.

Besides, Windows usually only requests disk initialization on brand new hard drives that haven't been used for data storage purposes yet. However, there are times when Windows requires a used disk (i.e. a hard drive with data) to be initialized - when it is first connected to a computer. If this is the case, you should pay attention to the data and be cautious while formatting, which is necessary to render the drive usable again.

Part 3. How to Safely Initialize a Hard Disk

If your hard disk is displaying the message "Disk 0 (1 or 2) Unknown, Not Initialized" or the disk space is showing unallocated space in Disk Management, then you need to initialize the disk to restore it to normal usage. The steps to initialize a disk are listed below:

select location

Step 1. Press the Windows key + R, and type "diskmgmt.msc". Then, click the Enter key to open the Windows Disk Management tool. 

Step 2. Select the problematic disk and right-click on it. 

Step 3. Select "Initialize Disk" and follow the Wizard to complete the process.
