I have a Dell 13-inch XPS 9370 that I bought in June 2018. After a Windows 10 update, I suddenly got repeated “Low Disk Space” warning messages on drive D:, which I didn’t create. After Googling, I found the solution. It turns out that this new drive D: is the recovery drive, and is not meant to have a drive letter. So the fix is to remove the drive letter and the annoying “Low Disk Space” warning messages will stop.
- Click your Start Button, type “cmd”, then right-click on “Command Prompt” and choose “Run as Administrator”
- Choose “Yes” when Windows asks if you want to allow the app to make changes to your computer
- Type “diskpart” and hit Enter
- Type “list volume” and hit Enter
- Type “select volume X” and hit Enter (where X is the volume number associated with that new drive with the ltr/letter D:)
- Type “remove letter=D” and hit Enter (where D is the drive letter that you want to remove)
- Close Command Prompt
