Hi,@Dani_S.Welcome to Microsoft Q&A. Formatting a USB drive and a CD-ROM using .NET 8 involves different approaches due to the different technologies and specifications involved.

To format a USB drive, you can use the System.Diagnostics namespace to execute command-line commands. For BitLocker, you could manage it using PowerShell commands.

using System;
using System.Diagnostics;
using System.IO;
class Program
{
    static void Main(string[] args)
    {
        string driveLetter = "E:"; // Change this to your USB drive letter
        try
        {
            FormatUSB(driveLetter);
            EnableBitLocker(driveLetter);
        }
        catch (Exception ex)
        {
            Console.WriteLine($"Error: {ex.Message}");
        }
    }

enter image description here

Formatting a CD-ROM is not typically supported directly in .NET because CD-ROMs are usually written with specific formats and are often used for one-time writing operations. Example Using Command Line Utility for CD-RWs.


var process = new Process
{
    StartInfo = new ProcessStartInfo
    {
        FileName = "cmd.exe",
        Arguments = "/c C:\\PathToYourCDFormattingTool.exe /format /driveletter E",
        RedirectStandardOutput = true,
        UseShellExecute = false,
        CreateNoWindow = true
    }
};

process.Start();
string result = process.StandardOutput.ReadToEnd();
process.WaitForExit();

Hi,@Dani_S. You could try the following example and see if it helps you.
.NET doesn't provide direct methods for formatting drives, so you can try using interop services to call the necessary Windows API functions.

For formatting a USB drive, you can use the InvokeMethod from ManagementObject.


using System;
using System.Diagnostics;
using System.IO;
using System.Management;

   static void Main()
   {
       string driveLetter = "E:"; // Replace with your USB drive letter
       FormatDrive(driveLetter);
       FormatCDROM(driveLetter);
   }
   static void FormatDrive(string driveLetter)
   {
       string query = $"SELECT * FROM Win32_Volume WHERE DriveLetter = '{driveLetter}'";
       using (ManagementObjectSearcher searcher = new ManagementObjectSearcher(query))
       using (ManagementObjectCollection results = searcher.Get())
       {
           foreach (ManagementObject volume in results)
           {
               try
               {
                   volume.InvokeMethod("Format", new object[] { "NTFS", true, 4096, "New Volume", false });
                   Console.WriteLine($"Drive {driveLetter} formatted successfully.");
               }
               catch (Exception ex)
               {
                   Console.WriteLine($"Error formatting drive {driveLetter}: {ex.Message}");
               }
           }
       }
   }

Hi,@Dani_S. Could you share more complete error message? After seeing your error message, I can't confirm the cause of the problem.

By the way, the first solution I provided should work according to my research.

First, you could check the name of your USB drive through the following code

public static void CheckDisk() { DriveInfo[] s = DriveInfo.GetDrives(); var result = string.Empty; foreach (DriveInfo i in s) { Console.WriteLine(i.Name); } }

Then execute the following code. Code function: Open cmd.exe and enter the command to format the disk and then return the result of the command.

According to your description, whether the USB encrypted with Bitlocker? If so, you need to unlock bitlocker first and then format the USB.

Whether have you tried to launch your program with administrator privileges?

the /c tells the cmd shell to exit after executing the command. otherwise the shell window is still open, and the start process won't complete until the user closes the shell window.

To add a little to this.

What is C:\PathToYourCDFormattingTool.exe? what i need to write.

This is a question that can only be answered by you.

To go into a little more detail, CD-ROMs are not things that can be formatted in the same way as hard disks or USB devices.

CDs, DVDs and BluRays are usually made out of metal, where the contents of the disk is pressed into the metal in a factory.

Writable medium, such as CD-Rs, CD-RWs, DVD-Rs, DVD-RWs and so on use ink to accomplish a compatible goal. Instead of the laser reflecting off of the metal, it reflects off of the ink instead. Even then, usually formatting isn't something that would be done.

For CD-Rs and DVD-Rs, writing to the disk is usually a two step process. The first step is to figure out the files that are going to be written to the disk and then works out the filesystem based upon this information. This normally outputs something like a .ISO file. The second step is to take this .ISO file and write it to the disk. There are tools to do this, but I do not believe that it is my responsibility to solve this problem.

However, since the initial question involved something unclear and, assuming CD-ROM was meant instead of CD-Rome, clearly impossible. I would like to suggest that the question and problem is revisited. Nobody on this forum is going to be willing to write all of the code and provide support if/when it goes wrong.

i got this error: "The type of the file system is RAW.

The new file system is UDF.

Formatting 128.0 KB

Whether the USB encrypted with Bitlocker? If so, you need to unlock bitlocker first and then format the USB. Have you unlocked the BitLocker?

the /c tells the cmd shell to exit after executing the command. otherwise the shell window is still open, and the start process won't complete until the user closes the shell window.

To add a little to this.

What is C:\PathToYourCDFormattingTool.exe? what i need to write.

This is a question that can only be answered by you.

To go into a little more detail, CD-ROMs are not things that can be formatted in the same way as hard disks or USB devices.

CDs, DVDs and BluRays are usually made out of metal, where the contents of the disk is pressed into the metal in a factory.

Writable medium, such as CD-Rs, CD-RWs, DVD-Rs, DVD-RWs and so on use ink to accomplish a compatible goal. Instead of the laser reflecting off of the metal, it reflects off of the ink instead. Even then, usually formatting isn't something that would be done.

For CD-Rs and DVD-Rs, writing to the disk is usually a two step process. The first step is to figure out the files that are going to be written to the disk and then works out the filesystem based upon this information. This normally outputs something like a .ISO file. The second step is to take this .ISO file and write it to the disk. There are tools to do this, but I do not believe that it is my responsibility to solve this problem.

However, since the initial question involved something unclear and, assuming CD-ROM was meant instead of CD-Rome, clearly impossible. I would like to suggest that the question and problem is revisited. Nobody on this forum is going to be willing to write all of the code and provide support if/when it goes wrong.

Why this code is not working?

The drive letter to "E:"

i got this error: "The type of the file system is RAW.

The new file system is UDF.

To format a CD-RW, you can use IMAPI2 and MsftDiscFormat2Erase

There is an old but good sample at Code Project : https://www.codeproject.com/Articles/24544/Burning-and-Erasing-CD-DVD-Blu-ray-Media-with-C-an

(Download source, main code is in backgroundFormatWorker_DoWork)

I tested similar code in C#/Net 8 and the formatting worked with a DVD-RW drive and a CD-RW (I did not use events (for % of progression))

I have problem in this row if you can help:

System.UnauthorizedAccessException: 'Access is denied. (0x80070005 (E_ACCESSDENIED))'

// Create and initialize the IDiscRecorder2

discRecorder = new MsftDiscRecorder2();

var activeDiscRecorder = driveLetter; //E:

discRecorder.InitializeDiscRecorder(activeDiscRecorder);

Castorix31 90,686

activeDiscRecorder is not a drive letter but a drive ID

In my test, I did this at beginning to get drive ID :

 					string? sRecorderId = "";                                    
                    MsftDiscMaster2 discMaster2 = new MsftDiscMaster2();
                    if (discMaster2.IsSupportedEnvironment)
                    {
                        IEnumerator recorderEnum = ((IEnumerable)discMaster2).GetEnumerator();
                        while (recorderEnum.MoveNext())
                        {
                            sRecorderId = recorderEnum.Current as string;
                            if (!string.IsNullOrEmpty(sRecorderId))
                                break;
                        }
                    }

                    if (!string.IsNullOrEmpty(sRecorderId))
                    {

OK.

I added your code but I got error:

This my code:

    IEnumerator recorderEnum = ((IEnumerable)discMaster2).GetEnumerator();

    while (recorderEnum.MoveNext())

    {

        sRecorderId = recorderEnum.Current as string;

        if (!string.IsNullOrEmpty(sRecorderId))

            break;

finally

The doc says :

E_IMAPI_RECORDER_LOCKED

If the device is already locked, you can call IDiscRecorder2::get_ExclusiveAccessOwner to retrieve the name of the client application that currently has exclusive access.

ChatGPT :

Previous Operation Not Released:

If a previous operation (such as formatting or burning) was not properly completed or the recorder wasn't released, it can remain locked.

You may need to explicitly release the recorder by calling the IDiscRecorder2::ReleaseExclusiveAccess method or ensure that the previous process has fully terminated.

Ensure you're calling IDiscRecorder2::AcquireExclusiveAccess before trying to perform actions like erasing or burning a disc.

When is it locked, what does this return ?

string sOwner = discRecorder.ExclusiveAccessOwner;

to check if is blocked by yourself or another process

Dani_S 4,501

It return null.

I wrapped the code with impersonation is it possible to work?.

When I used this code I got the client name but same error.

//

// Create and initialize the IDiscRecorder2

//

discRecorder = new MsftDiscRecorder2();
```discRecorder.InitializeDiscRecorder(sRecorderId);

                  

discRecorder.AcquireExclusiveAccess(true, "Format");

string clientName = discRecorder.ExclusiveAccessOwner; // Got Format

//

// Create the IDiscFormat2Erase and set properties

//

discFormatErase = new MsftDiscFormat2Erase

{

    Recorder = discRecorder,

    ClientName = clientName,

    FullErase = true

};

Does the full CodeProject sample also have this problem ?

Castorix31 90,686

Otherwise, there are other methods to format drives; a simple one is with SHFormatDrive, by displaying the Shell DialogBox

Declarations :

        [DllImport("Shell32.dll", SetLastError = true, CharSet = CharSet.Unicode)]
        public static extern uint SHFormatDrive(IntPtr hwnd, uint drive, uint fmtID, uint options);

        public int SHFMT_ID_DEFAULT = 0xFFFF;
        public int SHFMT_OPT_FULL = 0x0001;
        public int SHFMT_OPT_SYSONLY = 0x0002;

Can you list the cdrom to test?

Castorix31 90,686

You can use DriveInfo :

            string? sDriveLetter = "";
            DriveInfo[] allDrives = DriveInfo.GetDrives();
            foreach (DriveInfo drive in allDrives)
            { 
                if (drive.DriveType == DriveType.CDRom)
                {
                    sDriveLetter = drive.Name;                              
                }
            }

            char cLetter = sDriveLetter.ToUpper()[0];
            int nDriveNumber = cLetter - 'A';            
            SHFormatDrive(this.Handle, (uint)nDriveNumber, (uint)SHFMT_ID_DEFAULT, (uint)0);
