Why is D drive not showing up in Windows 10/11?
There are three most possible reasons accounting 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 D.
Sometimes, the DVD drive occupies 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 disappeared 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 installation due to inappropriate operations or other unknown reasons.
♦D drive is hidden.
If your system hides the D drive, then the D drive will not show up in Windows File Explorer as well.
♦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 the risk of disappearing 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 an 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.
