Alexander,

I'm happy to tell you I was wrong, with your help IOCTL_CDROM_RAW_READ works
fine under all circumstanes.
Great to get rid of the SPTI stuff.

I have some problems though.
I would like to get the name and version of the CD devices

If I get it right the way to go is to use IOCTL_STORAGE_QUERY_PROPERTY?

But the code snippet below won't compile

error C2065: 'STORAGE_DEVICE_DESCRIPTOR' : undeclared identifier

even though it's defined in ntddstor.h

It seems I'm not the only person having this problem

#include <windows.h>
#include <winioctl.h>

#include <devioctl.h>

#include <ntddstor.h>

void TestQueryProperties()

{

HANDLE hDevice = CreateFile("\\\\.\\%d:", GENERIC_READ, FILE_SHARE_READ |
FILE_SHARE_WRITE, NULL, OPEN_EXISTING, 0, NULL );

LPVOID lpOutput = NULL ;

DWORD dwSizeOfOutputBuffer = 0, dwSizeReturned = 0 ;

STORAGE_DEVICE_DESCRIPTOR *lpDeviceOutput = NULL ;

STORAGE_PROPERTY_QUERY sStorageInfo /*= {0}*/ ;

sStorageInfo.QueryType = PropertyStandardQuery ;

sStorageInfo.PropertyId = StorageDeviceProperty ;

dwSizeOfOutputBuffer = sizeof(STORAGE_DEVICE_HEADER) +
sizeof(STORAGE_DEVICE_DESCRIPTOR) ;

lpOutput = new BYTE[dwSizeOfOutputBuffer] ;

assert(lpOutput != NULL) ;

lpDeviceOutput =
reinterpret_cast<STORAGE_DEVICE_DESCRIPTOR*>(reinterpret_cast<LPSTR>(lpOutpu
t) + sizeof(STORAGE_DEVICE_HEADER)) ;

DeviceIoControl(hDevice, IOCTL_STORAGE_QUERY_PROPERTY, &sStorageInfo,

sizeof(sStorageInfo), lpOutput, dwSizeOfOutputBuffer, &dwSizeReturned,
NULL);

//........

CloseHandle(hDevice);

}

also I use IOCTL_STORAGE_EJECT_MEDIA and IOCTL_STORAGE_LOAD_MEDIA
to eject and close the CD which works fine.

and IOCTL_STORAGE_CHECK_VERIFY to check if a CD is in

If IOCTL_STORAGE_CHECK_VERIFY returns TRUE, the CD should be ejected
if it returns FALSE I assume the door is open and should be closed

but if the door is closed with no CD in, it should be ejected. How to
determine this?

Any hints appreciated

Thanks
Rolf
