启用Windows 10存储空间时，我需要获取系统中所有物理磁盘的以下信息。
到目前为止我尝试了什么：
GUID_DEVINTERFACE_DISK，将句柄传递给SetupDiGetDeviceInterface并使用SetupDiGetDeviceInterfaceDetail获取位置信息（总线/目标ID / LUN），PNP Id和设备路径。我可以将设备路径传递给CreateFile并获取其余信息（类似于this方法）。这个问题是它没有给我所有的物理磁盘。存储空间池下的磁盘被省略。启用存储空间后，如何获取每个物理磁盘的上述详细信息？
作为旁注，如果有一种方法可以使用CreateFile和DeviceIoControl从磁盘索引获取磁盘PNP id，这对我来说也非常有用。
首先，我们需要通过调用CM_Get_Device_Interface_ListW和CM_Get_Device_Interface_List_SizeW与GUID_DEVINTERFACE_DISK枚举系统中的所有磁盘
#include <Shlwapi.h>
#include <cfgmgr32.h>
#undef _NTDDSTOR_H_
#include <ntddstor.h>
#include <ntdddisk.h>
static volatile UCHAR guz;
CONFIGRET EnumDisks(PCSTR prefix, PGUID InterfaceClassGuid)
{
CONFIGRET err;
PVOID stack = alloca(guz);
ULONG BufferLen = 0, NeedLen = 256;
union {
PVOID buf;
PWSTR pszDeviceInterface;
};
for(;;)
{
if (BufferLen < NeedLen)
{
BufferLen = RtlPointerToOffset(buf = alloca((NeedLen - BufferLen) * sizeof(WCHAR)), stack) / sizeof(WCHAR);
}
switch (err = CM_Get_Device_Interface_ListW(InterfaceClassGuid,
0, pszDeviceInterface, BufferLen, CM_GET_DEVICE_INTERFACE_LIST_PRESENT))
{
case CR_BUFFER_SMALL:
if (err = CM_Get_Device_Interface_List_SizeW(&NeedLen, InterfaceClassGuid,
0, CM_GET_DEVICE_INTERFACE_LIST_PRESENT))
{
default:
return err;
}
continue;
case CR_SUCCESS:
while (*pszDeviceInterface)
{
DbgPrint("Interface=[%S]\n", pszDeviceInterface);
HANDLE hFile = CreateFileW(pszDeviceInterface, FILE_GENERIC_READ,
FILE_SHARE_VALID_FLAGS, 0, OPEN_EXISTING, 0, 0);
if (hFile != INVALID_HANDLE_VALUE)
{
GetDiskPropertyByHandle(hFile);
CloseHandle(hFile);
}
GetPropertyByInterface(prefix, pszDeviceInterface);
pszDeviceInterface += 1 + wcslen(pszDeviceInterface);
}
return CR_SUCCESS;
}
}
}
CONFIGRET EnumDisks()
{
char prefix[256];
memset(prefix, '\t', sizeof(prefix));
prefix[sizeof(prefix) - 1] = 0;
prefix[0] = 0;
return EnumDisks(prefix + sizeof(prefix) - 1, const_cast<PGUID>(&GUID_DEVINTERFACE_DISK));
}
CM_Get_Device_Interface_ListW返回多个以NULL结尾的Unicode字符串，每个字符串代表一个接口实例的符号链接名称。
从一侧，这个符号链接名称可以传递给CreateFileW用于打开磁盘设备。在此之后我们可以将一些ioctl设置为磁盘 - 用于获取
例：
void GetDiskPropertyByHandle(HANDLE hDisk)
{
HANDLE hPartition;
IO_STATUS_BLOCK iosb;
STORAGE_DEVICE_NUMBER sdn;
GET_LENGTH_INFORMATION li;
NTSTATUS status = NtDeviceIoControlFile(hDisk, 0, 0, 0, &iosb,

if (0 <= (status = NtDeviceIoControlFile(hDisk, 0, 0, 0, &iosb,

}
UNICODE_STRING ObjectName;

char PartitionName[256], *szPartitionName;

case STATUS_BUFFER_TOO_SMALL:

continue;

return ;
}
}
}
}
从另一个大小，我们可以通过调用Device Instance ID与CM_Get_Device_Interface_PropertyW从接口字符串中获取DEVPKEY_Device_InstanceId。在此之后，我们调用CM_Locate_DevNodeW获取设备实例句柄。
CONFIGRET GetPropertyByInterface(PCSTR prefix, PCWSTR pszDeviceInterface)
{
ULONG cb = 0, rcb = 256;
PVOID stack = alloca(guz);
DEVPROPTYPE PropertyType;
CONFIGRET status;
union {
PVOID pv;
PWSTR DeviceID;
PBYTE pb;
};
do
{
if (cb < rcb)
{
rcb = cb = RtlPointerToOffset(pv = alloca(rcb - cb), stack);
}
status = CM_Get_Device_Interface_PropertyW(pszDeviceInterface, &DEVPKEY_Device_InstanceId, &PropertyType, pb, &rcb, 0);
if (status == CR_SUCCESS)
{
if (PropertyType == DEVPROP_TYPE_STRING)
{
DbgPrint("%sDeviceID = %S\n", prefix, DeviceID);
DEVINST dnDevInst;
if (CR_SUCCESS == (status = CM_Locate_DevNodeW(&dnDevInst, DeviceID, CM_LOCATE_DEVNODE_NORMAL)))
{
GetPropertyByDeviceID(prefix, dnDevInst);
}
}
else
{
status = CR_WRONG_TYPE;
}
break;
}
} while (status == CR_BUFFER_SMALL);
return status;
}
使用设备实例句柄，我们可以通过CM_Get_DevNode_PropertyW查询许多设备属性，如：DEVPKEY_Device_LocationInfo，DEVPKEY_NAME，DEVPKEY_Device_PDOName，DEVPKEY_Device_FirmwareVersion，DEVPKEY_Device_Model，DEVPKEY_Device_DriverVersion等等 - 在devpkey.h中查看完整列表
最后我们可以调用CM_Get_Parent并递归查询父设备的所有这些属性，直到我们没有丰富的堆栈顶部：
#define OPEN_PDO
void GetPropertyByDeviceID(PCSTR prefix, DEVINST dnDevInst)
{
#ifdef OPEN_PDO
HANDLE hFile;
IO_STATUS_BLOCK iosb;
UNICODE_STRING ObjectName;
OBJECT_ATTRIBUTES oa = { sizeof(oa), 0, &ObjectName, OBJ_CASE_INSENSITIVE };
#endif
CONFIGRET status;
ULONG cb = 0, rcb = 0x80;
PVOID stack = alloca(guz);
DEVPROPTYPE PropertyType;
union {
PVOID pv;
PWSTR sz;
PBYTE pb;
};
static struct
{
CONST DEVPROPKEY *PropertyKey;
PCWSTR PropertyName;
} PropertyKeys[] = {
{ &DEVPKEY_Device_PDOName, L"PDOName"},
{ &DEVPKEY_Device_Parent, L"Parent"},
{ &DEVPKEY_Device_DriverVersion, L"DriverVersion"},
{ &DEVPKEY_Device_LocationInfo, L"LocationInfo"},
{ &DEVPKEY_Device_FirmwareVersion, L"FirmwareVersion"},
{ &DEVPKEY_Device_Model, L"Model"},
{ &DEVPKEY_NAME, L"NAME"},
{ &DEVPKEY_Device_InstanceId, L"DeviceID"}
};
do
{
int n = RTL_NUMBER_OF(PropertyKeys);
do
{
CONST DEVPROPKEY *PropertyKey = PropertyKeys[--n].PropertyKey;
do
{
if (cb < rcb)
{
rcb = cb = RtlPointerToOffset(pv = alloca(rcb - cb), stack);
}
status = CM_Get_DevNode_PropertyW(dnDevInst, PropertyKey, &PropertyType, pb, &rcb, 0);
if (status == CR_SUCCESS)
{
if (PropertyType == DEVPROP_TYPE_STRING)
{
DbgPrint("%s%S=[%S]\n", prefix, PropertyKeys[n].PropertyName, sz);
#ifdef OPEN_PDO
if (!n)
{
// DEVPKEY_Device_PDOName can use in NtOpenFile
RtlInitUnicodeString(&ObjectName, sz);
if (0 <= NtOpenFile(&hFile, FILE_READ_ATTRIBUTES|SYNCHRONIZE, &oa,
&iosb, FILE_SHARE_VALID_FLAGS, FILE_SYNCHRONOUS_IO_NONALERT))
{
NtClose(hFile);
}
}
#endif
}
}
} while (status == CR_BUFFER_SMALL);
} while (n);
if (!*--prefix) break;
} while (CM_Get_Parent(&dnDevInst, dnDevInst, 0) == CR_SUCCESS);
}
还有DEVPKEY_Device_PDOName返回的字符串我们可以在NtOpenFile中使用调用开放PDO设备。
