Unmounting a USB Pen-Drive via code

Question

I wonder how I can do to disassemble a removable drive(Pen-Drive) via c code#.

Answer 1

From Windows XP you can use the native command MOUNTVOL. According to your documentation:

Creates, Labels, or lists a volume mount point. Mountvol is a way to link volumes without requiring a drive Letter.

Translating:

Create, delete or list a mount point volume. Mountvol is a way to link volumes without the need for a drive letter.

Using its code as the basis, this would be the call without the need for any external component:

private static void EjectDrive(char driveLetter)
{
    ProcessStartInfo ps = new ProcessStartInfo("mountvol.exe", driveLetter + ": /d");
    Process.Start(ps);
}

Once I looked at this link, I was trying to do the same solution and I had found these models, but I no longer needed them, I used file transmission via Dropbox, so I abandoned the project.

who knows gives you a light! :)

Answer 3

So, you guys, let’s go I managed to find a program that does this.

And I did it that way.

private static void EjectDrive(char driveLetter)
    {
        ProcessStartInfo ps = new ProcessStartInfo("RemoveDrive.exe", driveLetter + ":");
        Process.Start(ps);
    }

Along with this Removedrive at the root of the program. Obg Galera.
