Hi,

Currently I am using Diskpart (Windows command line utility) to manage disks and assign drive letters.
Disk 0 is present almost 99.99% scenarios, however, I need to check for the disk 1 and disk 2 all the time.
If disk 1 is present, assign letter 'Z' to partition 1 and 'X' to partition 2 (if exists). Otherwise, check if disk 2 is present and if yes assign letter 'M' to partition 1 and so on.. as in below screenshot.
Can same check /configured using VB.Net?

    Hi @~OSD~ ,
    You can also try using Process class to execute the Diskpart command.

            Dim p As Process = New Process()  
            p.StartInfo.UseShellExecute = False  
            ' Redirect the results on screen.  
            p.StartInfo.RedirectStandardOutput = True  
            p.StartInfo.FileName = "C:\Windows\System32\diskpart.exe"  
            p.StartInfo.RedirectStandardInput = True  
            p.Start()  
            p.StandardInput.WriteLine("list disk")  
            p.StandardInput.WriteLine("exit")  
            Dim output As String = p.StandardOutput.ReadToEnd()  
      
            If output.Contains("Disk 1") Then  
                p.Start()  
                p.StandardInput.WriteLine("select disk 1")  
                ' Assign letter 'Z' to partition 1.  
                p.StandardInput.WriteLine("assign ...")  
                p.StandardInput.WriteLine("exit")  
                output = p.StandardOutput.ReadToEnd()  
                p.WaitForExit()  
                Console.WriteLine(output)  
            End If  
            p.WaitForExit()  
            Console.ReadLine()  
    

    Hope it could be helpful.

    Best Regards,
