Disk Unknown Not Initialized? Here are 4 Powerful Solutions to Fix It!

Secure Disk Initialization Steps:

  1. Press Win + R, type diskmgmt.msc, and then press Enter (open Disk Management).
  2. Look for disks with the status “Unknown” and “Not Initialized”.
  3. Right-click on the disk → select “Initialize Disk”.
  4. Select the partition table:
    • MBR (Master Boot Record) → Suitable for disks<2TB or those that will be used on older Windows.
    • GPT (GUID Partition Table) → More modern, suitable for disks>2TB or used on UEFI systems.
  5. Click OK and wait for the process to complete.

Solution 4: Save Data & Disk Format – The Last Step If All Else Fails

Disk still unreadable after initialization? Maybe the partition is severely damaged. But don’t worry, your data may still be salvageable!

Data Recovery + Format Steps:

1. Use Recovery Software (e.g., EaseUS Data Recovery, Recuva, or Disk Drill):

2. Once the data is safe, the disk format:

  • Open Disk Management → Right-click → Format disk.
  • Select the file system:
    • exFAT → If you want to be compatible with Mac/Linux as well.
  • Name the volume & click OK.

Don’t save the recovered data to the same disk! It can overwrite the original data.
If the disk still fails after formatting, there may be physical damage.
