错误分区和格式化USB闪存驱动器在C + +
问题描述：
我卡住尝试重新分区和使用C++格式化USB闪存驱动器，任何帮助将是伟大的！错误分区和格式化USB闪存驱动器在C + +
目标是用占用整个空间和格式化FAT32（稍后的选项NTFS和EXFAT）的单个分区重新分区任意的闪存驱动器。这将分批完成，希望一次有50多个设备，因此不能选择驱动器号访问。我能够创建一个分区，但是当我尝试IOCTL_DISK_SET_PARTITION_INFO_EX来设置格式类型时，它将以0x32，ERROR_NOT_SUPPORTED失败。但目前尚不清楚究竟哪些不支持。我可以使用实用程序（如diskpart）手动对设备进行分区，因此我知道设备支持分区和文件系统类型。谁能帮忙？我的完整源代码如下，在使用IOCTL_DISK_SET_PARTITION_INFO_EX调用DeviceIoControl（）时失败。

我有一个解决方案，但它有点复杂。我使用上面的DeviceIoControl（）来分区磁盘。然后，我使用VDS和IID_IVdsVolumeMF界面来创建文件系统，但是到那里工作有点麻烦。目标是对系统上的所有闪存驱动器（USB记忆棒）进行分区和格式化。 VDS将通过IID_IVdsVolumeMF接口执行格式，但它不会告诉您（至少我没有弄清楚）哪些设备是可移除的。但是WMI会告诉你哪些设备是可移动的，但没有格式化功能。所以......
首先使用WMI来获取系统中所有移动量路径列表，例如：
CoCreateInstance(CLSID_WbemLocator, 0, CLSCTX_INPROC_SERVER, IID_IWbemLocator, (LPVOID *)&pLoc)
pLoc->ConnectServer(CComBSTR(L"ROOT\\CIMV2"), nullptr, nullptr, nullptr, 0, nullptr, nullptr, pWbemSvc)
CoSetProxyBlanket(
*pWbemSvc, // Indicates the proxy to set
RPC_C_AUTHN_WINNT, // RPC_C_AUTHN_xxx
RPC_C_AUTHZ_NONE, // RPC_C_AUTHZ_xxx
NULL, // Server principal name
RPC_C_AUTHN_LEVEL_CALL, // RPC_C_AUTHN_LEVEL_xxx
RPC_C_IMP_LEVEL_IMPERSONATE, // RPC_C_IMP_LEVEL_xxx
NULL, // client identity
EOAC_NONE // proxy capabilities
pWbemSvc->ExecQuery(CComBSTR(L"WQL"), CComBSTR(L"SELECT * FROM Win32_Volume WHERE DriveType=2"), WBEM_FLAG_FORWARD_ONLY | WBEM_FLAG_RETURN_IMMEDIATELY, NULL, &pEnumerator)
为您提供了诸如路径：
L"\\\\?\\Volume{3899cb7b-7c3f-11e6-bf82-005056c00008}\\"
然后使用VDS获取机器上所有VDS卷的列表。基本上你加载VDS，然后得到所有的软件提供商。这个来源是失踪了简短的部分，但我想我留下了足够的解释发生了什么：
pEnumProviders->Next(1, &pUnk, &cFetched)
pProv = pUnk;
pProv->QueryPacks(&pEnumpacks)
vPacks.push_back(pEnumpacks);
现在遍历：
pSvc->QueryProviders(VDS_QUERY_SOFTWARE_PROVIDERS, &pEnumProviders)
通过供应商正从各个供应商的包列表现在迭代礼包并获得所有在每个包的卷：
iterator iPacks = vPacks.begin();
(*iPacks)->Next(1, &pUnk, &cFetched)
pPack = pUnk;
pPack->QueryVolumes(&pEnumvolumes)
pvpEnumvolumes->push_back(pEnumvolumes)
现在你有路径可移动设备的列表，你必须在系统上所有卷的列表。时间来比较它们，并找出哪些卷是可移动。
iVolEnum = pvpEnumOfVDSVolumes->begin()
(*iVolEnum)->Next(1, &pUnk, &cFetched)
pVMF3 = pUnk;
CComHeapPtr<LPWSTR> pVDSVolumePaths;
pVMF3->QueryVolumeGuidPathnames(&pVDSVolumePaths, &nPaths)
iterator iWMIVolPath = pvWMIRemovableVols->begin();
loop..
if (wcscmp(iWMIVolPath->data(), pVDSVolumePaths[i]) == 0)
{ // VDS Vol is removable! }
现在使用VDS卷对象格式化卷：
foreach(vol in vRemovableVDSVols)
{
CComQIPtr<IVdsVolume> pVolume = *(vol);
IVdsVolumeMF *pVolumeMF;
pVolume->QueryInterface(IID_IVdsVolumeMF, (void **)&pVolumeMF);
pVolumeMF->Format( VDS_FST_FAT32,
L"MyFob",
512, // alloc size
true, // force
false, // quick
false, // compression
&pAsync); // async
}
而急的U盘格式化！呃..但它似乎在工作。
微软真的没有让这个更容易吗？
您是否曾尝试以管理员身份运行程序（通过“以管理员身份运行”）？ – 1201ProgramAlarm
“IOCTL_DISK_SET_PARTITION_INFO_EX”的用途是什么？您已经在上面的'IOCTL_DISK_SET_DRIVE_LAYOUT_EX'中设置了分区类型。 –
感谢您的建议。是的，我尝试右键单击并“以管理员身份运行”，结果是相同的，错误0x32 ERROR_NOT_SUPPORTED。 – Matt
