很简单的代码，我打开PhysicalDrive1就可以，但打开C:就错误，请问这是为什么？
#include <stdio.h>
#include <windows.h>
#include <winioctl.h>
int main(void)
{
//LPCTSTR lpszDevice = "\\\\.\\PhysicalDrive1";
LPCTSTR lpszDevice = "\\\\.\\C:";
HANDLE hDevice = CreateFile(lpszDevice,GENERIC_READ,FILE_SHARE_READ,NULL,OPEN_EXISTING,0,NULL);
if (!hDevice || (hDevice==(HANDLE)-1))
{
printf("Open Device error:0x%x\n",GetLastError());
return -1;
}
DWORD temp;
const int SECTOR_SIZE = 512;
UCHAR buffer[SECTOR_SIZE];
ReadFile(hDevice,buffer,SECTOR_SIZE,&temp,NULL);
CloseHandle(hDevice);
return 0;
}
