FileIOPermissions - Preventing write access to a directory

Question

See more:

I'm currently working on a project that would prevent write access to a usb flash drive when it's inserted into a machine. I've looked into using the FileIOPermission class to make the assembly have read-only access, but would using that class prevent other applications from writing to the drive?
I've also looked at editing the registry from this article[^], but that would prevent write access to all usb devices.

Is there a way to prevent write access to one usb device?

The first thought that comes to mind is using a USB flash-drive that can be password-protected. This company claims its password-protection software is free: [^], but I have never used it.

This CP article may be helpful as a starting point: "Developing a USB Storage Device Protection Tool with C# By Ozcan ILIKHAN | 5 Jun 2009:" [^].

But, it does show techniques for write-protecting all USB drives, not a specific one.

See discussion here: [^] for other ideas. And discussions on SO here:[^].
