Hi,
I have C++ Code that query HD property of all drives connected to the system. The code sends IOCTL_STORAGE_QUERY_PROPERTY, with DeviceIOControl function. This code works great on Windows XP, however on Windows Server 2008 SP2 (64 bit), it fails with error code 87. I am able to read device properties from \\.\PhysicalDrive0 - boot drive, but not from any other drives. I have 3 hd connected, all SAS drives.

Here is the code. Please help.

HANDLE hdl=drive_handle;
DWORD bytesRet;
DWORD outSize;
DWORD error;
STORAGE_PROPERTY_QUERY input;
STORAGE_DEVICE_DESCRIPTOR *output;

Memset(&input, 0, sizeof(input));

input.PropertyId = StorageDeviceProperty;
input.QueryType = PropertyExistsQuery;

if(!DeviceIoControl(hdl,
IOCTL_STORAGE_QUERY_PROPERTY,
&input,
sizeof(STORAGE_PROPERTY_QUERY),
NULL,
0,
&bytesRet,
NULL))
{
error = GetLastError();
tsVerbose(1,"Failed to storage property query, error %d", error);
return FALSE;
}
