Sorry! I forgot to change the subject in the previous email.
Thank you for your help! No luck so far.
I wrote a C program and got the same results as python:
Win 7 Notebook (with SD card inserted directly i.e. no SD card reader) Error
code: 1
Win 7 Notebook (without SD card inserted at all) Error code: 6
WinXP desktop (with USB stick but without SD card inserted at all) Error code:
50
int main(int argc, char* argv[])
{
string sdrive("\\\\.\\e:");
HANDLE hcd = CreateFile(sdrive.c_str(),
GENERIC_READ,
FILE_SHARE_READ|FILE_SHARE_WRITE,
NULL,
OPEN_EXISTING,
FILE_ATTRIBUTE_READONLY,
NULL);
if (hcd == INVALID_HANDLE_VALUE)
printf("Could not open drive\\\n");
else
printf ("%s \n", "opened drive");
DWORD d = 0;
int nSizeOfCmd = sizeof(SFFDISK_QUERY_DEVICE_PROTOCOL_DATA) ;
SFFDISK_QUERY_DEVICE_PROTOCOL_DATA *pCmdBuf =
(SFFDISK_QUERY_DEVICE_PROTOCOL_DATA*) new BYTE[nSizeOfCmd];
memset(pCmdBuf, 0, nSizeOfCmd);
BOOL bResult=DeviceIoControl(hcd, IOCTL_SFFDISK_QUERY_DEVICE_PROTOCOL, NULL,
0,
pCmdBuf, nSizeOfCmd, &d, NULL);
DWORD dwErr = GetLastError();
CloseHandle(hcd);
if(!bResult){
printf("Failed to get ProtocolGUID, err code: %d",dwErr);
}
else{
printf("%s \n", pCmdBuf->ProtocolGUID);
}
delete [] pCmdBuf;
return 0;
}
Thank you,
Jane

What I would do is write the code as a C program just to make sure the
API does what I expect. That at least eliminates the Python layers from
consideration.
What SD card reader are you using? Not all of the behave nicely.
