[求解]利用IOCTL_DISK_SET_DRIVE_LAYOUT_EX给磁盘分区
先上一段代码， 该代码根据网上找到的修改了一下，注释（英文的）基本没删。
"\\\\.\\PhysicalDrive1" 是我的U盘的符号连接。。
DWORD func()
{

// Very important! Size correctly this structure. Even if there's only
// one primary partition, you MUST size the buffer to contain
// AT LEAST 4 PARTITION_INFORMATION_EX!
szNewLayout = sizeof(DRIVE_LAYOUT_INFORMATION_EX) +
(PartitionCount - 1) * sizeof(PARTITION_INFORMATION_EX);

// NtCreateFile() function can be used too with "\\device\\harddisk1\\partiton0" path.

_T("\\\\.\\PhysicalDrive1"),
