我使用 IOCTL_STORAGE_GET_MEDIA_TYPES_EX 來取得光碟機的型態， 但情況不如預期，雖然 DeviceType 能區分出 DVD 和 CD，不過 MediaType 都是 CD-ROM， DEVICE_MEDIA_INFO 的參數 MediaCharacteristics 也都顯示唯獨讀。    想請問以下程式碼是否有問題？ 或者有其他簡易的方式可以辨別燒錄機？    
// 請放一個 Memo 和 Button 元件，include winioctl.h
// IOCTL_STORAGE_GET_MEDIA_TYPES_EX 可能返回不止一條 DEVICE_MEDIA_INFO，故定義足夠的空間
#define MEDIA_INFO_SIZE  sizeof(GET_MEDIA_TYPES) 15*sizeof(DEVICE_MEDIA_INFO)
//---------------------------------------------------------------------------
void __fastcall TForm1::Button21Click(TObject *Sender)
{
        Memo1->Lines->Clear();            AnsiString disk = "\\\\.\\F:"; // 光碟機磁碟代號
        HANDLE hDevice = CreateFile(disk.c_str(), GENERIC_READ | GENERIC_WRITE,
                                    FILE_SHARE_READ |  FILE_SHARE_WRITE, NULL, OPEN_EXISTING, 0, NULL);            if(hDevice == INVALID_HANDLE_VALUE) return;            GET_MEDIA_TYPES *pmt = (GET_MEDIA_TYPES *)new BYTE[MEDIA_INFO_SIZE];
        DWORD cbBytesReturned = 0;            if(DeviceIoControl(hDevice, IOCTL_STORAGE_GET_MEDIA_TYPES_EX,
                           NULL, 0, pmt, MEDIA_INFO_SIZE, &cbBytesReturned, NULL))
        {
                Memo1->Lines->Add("DeviceType: "   PrintDeviceType(pmt->DeviceType));
                Memo1->Lines->Add("MediaType: "   PrintMediaType(pmt->MediaInfo[0].DeviceSpecific.RemovableDiskInfo.MediaType));
                Memo1->Lines->Add("MediaCharacteristics: "   PrintMediaChrar(pmt->MediaInfo[0].DeviceSpecific.RemovableDiskInfo.MediaCharacteristics));
        }else Memo1->Lines->Add("GetLastError: "   AnsiString(GetLastError()));            delete pmt;
        CloseHandle(hDevice);

ATAPI Command中有一個Command[Mode Sense]可以知道碟機特性 他會回覆碟機可讀寫的碟片種類 根據回覆的表，你就知道這台光碟是哪一種類型了 不過，你要先能下ATAPI Command

這個範例真是讓我受益良多～ 而 IOCTL_SCSI_PASS_THROUGH 正是我需要的～ 感謝 kcin ～ 也謝謝 blk5743 提供資訊～ 有機會的話再研究如何下 ATAPI Command 了～ 以下是擷取出來的程式碼～
