Reasons for D Drive Missing

If the D drive still does not show up, the following reasons are likely to blame for “D drive missing”:

The D drive might be deleted accidentally.

This reason may sound ridiculous but it is possible. Recall what you have done before you discover the issue.

The drive letter D might be taken up by the CD/DVD drive or the USB flash drive.

Sometimes, when installing the system on some servers, the drive letter D is assigned to the CD-ROM drive by default. In this stance, it seems that your D drive is missing.

USB flash drive can also take up the drive letter D. If you use it for installing the system but do not remove it immediately during the installation, the system will regard it as the D drive and other drives will be marked as F/F/G… orderly.

The D drive is hidden.

To identify whether your D drive is hidden, you just need to perform a simple calculation — check whether the capacity of all drives and unallocated space is equal to the disk capacity. If not, it indicates that your D drive has been hidden by a system tool.

The D drive might be included in the C drive.

Some users said that they chose the wrong option when installing the system, causing the entire hard drive to be installed as a C drive.

The drive drivers are outdated.

Outdated drive drivers can also lead to D drive not showing up in the computer.

These are the common reasons for D drive not showing up in Windows. Now, scroll down to see how to recover the lost data and get the D drive back.
