怎样写一个驱动就能禁止光驱、软驱、USB，高分相送

怎样写一个驱动就能禁止光驱、软驱、USB，高分相送

已经搞定，现在光驱、软驱测试通过

基本上就是用IoGetRelatedDeviceObject挂接设备
    fileSysDevice = IoGetRelatedDeviceObject( fileObject );
pDriverObject = fileSysDevice->DriverObject;

然后拦截此DriverObject的IRP_MJ_CREATE、IRP_MJ_SET_INFORMATION、IRP_MJ_DEVICE_CONTROL

返回STATUS_INSUFFICIENT_RESOURCES就行了

对\\Device\\Floppy0拦截，应该可以的

U盘和移动硬盘可以通过应用程序判断，先取到盘符，再根据盘符
取得此盘符所在的位置，是USB口的就是移动硬盘了

当然要先判断一下是否为 可移动设备，如不是再做上面判断

不好意思，最近一直在外地出差，等回来把代码放上来

long GetBusType(char disk)
{
CHAR szDriveName[MAX_PATH];
sprintf (szDriveName,"\\\\.\\%c:", disk);
HANDLE hDevice;

hDevice = CreateFile (szDriveName,
GENERIC_READ,
FILE_SHARE_READ | FILE_SHARE_WRITE,
NULL,
OPEN_EXISTING,
0,
NULL);
if (hDevice == INVALID_HANDLE_VALUE)
{
return -1;
}
else
{
DWORD dwBytesReturned, dwRetCode;
int buf_size = 4096;
char buf[4096];

STORAGE_PROPERTY_QUERY query;

memset ((void *)&query, 0, sizeof (query));
query.PropertyId = StorageDeviceProperty;
query.QueryType = PropertyStandardQuery;

dwRetCode = DeviceIoControl (hDevice,
IOCTL_STORAGE_QUERY_PROPERTY,
&query,
sizeof (query),
(STORAGE_DEVICE_DESCRIPTOR *) buf,
buf_size,
&dwBytesReturned,
NULL);
if(!dwRetCode)
{
CloseHandle (hDevice);
return -1;
}
STORAGE_DEVICE_DESCRIPTOR   *info= (STORAGE_DEVICE_DESCRIPTOR *)buf;

CloseHandle (hDevice);
return info->BusType;
}
}
void test()
{
int iType = GetDriveType("C:\\");
switch( iType )
{
case 0:
case 1:
break;
case DRIVE_REMOVABLE:
//这儿是USB
break;
case DRIVE_CDROM:
break;
case DRIVE_FIXED:
long lBusType = GetBusType('C');
if(lBusType != BusTypeUsb)
{
//这儿是硬盘分区
}
else
{
//这儿是移动硬盘分区
}
break;
case DRIVE_REMOTE:
break;
case DRIVE_RAMDISK:
break;
}
}

写个程序调用test()函数，应该不会出问题的
