如何在多媒体卡上的指定扇区上书写？

我必须绕过文件系统并直接写/读。

解决方案

你不能使用.net这样做，这是肯定的。你将不得不进行调用。

即便如此，我也不记得任何win32函数可以让你指定你要写入的扇区

。


你的装配怎么样？ :)

你不必绕过FS，你只需要打开物理设备
使用Win32的API

CreateFile通过PInvoke。成功的CreateFile返回一个文件句柄

，您可以使用

FileStream类在物理级别读取/写入设备。

物理设备看起来像\\.\PhysicalDrive< n> （硬盘以n =

0开头），您也可以使用它的mountpoint来引用物理设备

" \\。\ C："或卷ID \\？\ Volume {guid} \

这看起来很有趣。我可以通过谷歌了解更多关于

这些路径的信息？你知道他们怎么称呼这样的路径标识符吗？到目前为止，我无法获得
。

How can i write on specifyed sector on a multimedia card?
I must go round file system and write/read direct.
C# VS2003

Thanks

解决方案

Hi,

You cannot do this using .net , that''s for sure. you will have to p/invoke .
Even so I don''t remember any win32 function that let you especify the sector
you want to write into.

How is your assembly? :)

You don''t have to go round the FS, you just have to open the physical device
using Win32''s API
CreateFile through PInvoke. When successful CreateFile returns a file handle
which you can use to read/write to the device at the physical level using
the FileStream class.

A physical device looks like \\.\PhysicalDrive<n> (hard disks start with n =
0), you can also refer to a physical device by using it''s mountpoint
"\\.\C:" or volume ID \\?\Volume{guid}\

That looks interesting. What could I google for to learn more about
these paths? Do you know how they call such path identifiers? I couldn''t
find much so far.
