D Drive Missing in Windows 10 

"I have installed Windows 10 on my Alienware a few weeks ago and I cannot see my D drive now. It seems like completely missing from my computer. Worse is, I saved all data on that drive. Does anyone know what can be the problem of my computer? I need all data back at the same time. Any advice will be appreciated."

It is a helpful post on how to find the lost D drive in Windows 10 after installing. As a matter of fact, people would find their local disk D missing in Windows 7 as well, E drive missing sometimes. Generally, we install operating system on C drive and install some third-party as well as our crucial personal data on D drive or E drive. It will be quite annoying if we lost those files. When and why would that happen? How could we get the lost partition back exactly? Let’s keep reading.

Why can’t we see D Drive in Windows 10/11?

There are three most possible reasons account for the D drive suddenly missing problem in general. Find the reason so we can find the cure.

  • The CD or DVD drive takes up the drive letter. Sometimes, the DVD drive is occupying the drive after a reboot or reconfiguration. The issue also results to a problem: we cannot change drive letter to D drive. We can check it in Windows Disk Management. If yes, right click it and select Change Drive Letter and Paths to assign it a different drive letter.

  • D drive missing after Windows 10 update. We may get the issue after an update or installation like files missing after Windows 10 update. Some system settings are changed after the install due to inappropriate operations or other unknown reasons.

  • D drive has been formatted or deleted accidentally. When we do some operations on partitions or hard drives like adjusting partition size or reformating a hard drive, the related drives have risk to disappear under mistaken operations.

In a few cases, the D drive is not missing but the drive letter missing. In that case, we can assign a drive letter to that partition marked as asterisk in Diskpart or Disk Management. There might be other possible reasons for D drive missing that are not listed. Next, we’ll offer different solutions for this issue.

How to Restore Local Disk D Drive in Windows 10/11 Easily?

In the first place, there are two common ways we can try to get D drive back in Windows 10/11.

Rescan Disks

Go to Disk Management, click “Action” on the toolbar and then select “Rescan disks” to let system perform a re-identification for all connected disks. See if the D drive will appear after that.

Restore System

If we have created system restore points regularly on the computer, it would be much easier for us to return the PC to a normal status where the D drive is still there. Given that there are sufficient system restore points:

1. Type system restore on the Search box in Windows 10. Click “Create a restore point” from the list.

2. In the pop out window, click System Restore to start.

3. Follow the wizard to select the correct system point for restoring. It will take anywhere from 10 to 30 minutes.

Tips: Once started, System Restore cannot be interrupted. The computer will restart later, so be sure all programs are closed.
