Windows RAMDisk Storage Driver Sample. Drive with the name 'R' does not exist

Context: Playing with Microsoft RAMDisk Storage Driver Sample. Build and installation of the driver went smoothly. Verified that the Ramdisk service exist in the registry, and could see the Ramdisk device in Device Manager.

Issue: When trying to access the Ramdisk device (Drive R:) via Windows PowerShell to perform IO I get the following error message:

Set-Location : Cannot find drive. A drive with the name 'R' does not exist.
At line:1 char:1

Set-Location R:
~~~~~~~~~~~~~~~
CategoryInfo : ObjectNotFound: (R:String) [Set-Location], DriveNotFoundException
FullyQualifiedErrorId : DriveNotFound,Microsoft.PowerShell.Commands.SetLocationCommand

Attempted to access the Ramdisk via Command Prompt and File Explorer without success.

Question: What am I doing wrong?

Development Environment:

  • Windows 10 Pro 64-bit
  • Visual Studio 2015
  • WDK 10

Target Environment:

  • Windows 10 Enterprise Evaluation 64-bit (Build 10586)
  • Debug and Test mode enabled
Solution

  • Root Cause: The Ramdisk sample driver is not properly handling disk device requests for Windows 10.

    Solution: Updated the Ramdisk sample driver to properly handle disk device request. See Windows driver sample pull request #53 for details.

    Note: This code has only been tested on Windows 10, and will only allow you to access the Ramdisk via Windows PowerShell, or Command Prompt. File Explorer still doesn't work; please let me know, if anyone was able to get File Explorer working.
