DISK_GEOMETRY_EX

NTDEV
1

I am using DISK_GEOMETRY_EX structure in my program but get the following error:

error C2065: ‘DISK_GEOMETRY_EX’ : undeclared identifier

I am using Visual C++ 6.0 and Windows XP SP2.

Which SDK should I download to update the headers.

Please help.

Thanks

Have you included “Winioctl.h”?

Its in the Platform SDK August 2001 +

Regards

Wrong place too ask…

Anyhow, why not copy it out of the Server 2003 R2 sdk? Why not just add
the declaration to your
own header off the msdn site like…

typedef struct _DISK_GEOMETRY_EX {
DISK_GEOMETRY Geometry;
LARGE_INTEGER DiskSize;
BYTE Data[1];
} DISK_GEOMETRY_EX,
*PDISK_GEOMETRY_EX;

In general suggestions to cut and paste include file contents, rather
than using a well constructed build environment, are in the category of
‘bad advice’. There are exceptions. Include the correct sdk files and
specifying the correct sdk version are well documented and well
understood and trivial to accomplish.

The OP should download the latest platform sdk and read the
documentation and build his application for the correct platform level
that supports this structure.

The sdk documentation includes all of the required information:
Client Requires Windows XP.
Server Requires Windows Server 2003.
Header Declared in Winioctl.h.

Yes, but he is using VC 6. Last time I tried to use new headers with it
there were issues with
header versioning, annotations, runtime/lib clashes, etc… Just one
thing after another to deal with.

Ok first thanks to all.

Let me explain my problem and seek your advice.

I am doing sector-level IO on a compact flash card (in user-mode). This I am doing because I am developing a custom file system for the compact flash card which will be used imy embedded system. However, I am not getting the correct Disk Size using DeviceIoControl which is very important for my formatting program.

I have had an experience of developing FAT file system driver before for my embedded system.
However, I am somewhat inexperienced in Win32 API.

I need your advice as to what development platform should I use (till now I am using Visual C 6.0) which will fulfill all my needs. My custom file system driver will run on Windows XP.

Thanks
dranne

I build everything from MFC apps to KMDs with build.exe instead of any
IDE except for cranking up some quick test program. (well, I must admit
I’m not a big fan of build.exe). PSDK path is added to the sources as
needed. In such way, it’s easy for my source control, build and disaster
recovery.

I agree with Mark that having a well constructed build env is important.

If you are looking into writing a FSD for WXP, you definitely want to
check out IFS kit or the WDK6000 which includes former IFS kit. You
should also join the NTFSD mailing list.

I have installed the Platform SDK and replaced winioctl.h. Although the header has the declaration for DISK_GEOMETRY_EX. But I am getting the same error when I declare a variable for DISK_GEOMETRY_EX
error C2065: ‘DISK_GEOMETRY_EX’ : undeclared identifier

What is the problem. Can anyone help. Is there something wrong with my compiler? Or I am missing something.

Make sure you have defined _WIN32_WINNT > 0x0500.

Right before the declaration there is a line

#if(_WIN32_WINNT >= 0x0500)

Add

#define _WIN32_WINNT 0x0500 // at least

before anything (before the 1st header).

#if(_WIN32_WINNT >= 0x0500)

You have not specified the correct platform level in your build
environment. This is all documented in the SDK documentation.

Sounds like VS is still looking at your old include files.

In Visual studio settings, all search paths (for headers, libs, etc) are
ordered from top (first path to search) to
the bottom of the list (last path to look in).

If you look in your include path settings, use the ‘arrows’ to move your
new include path towards the top of the list,
VS will use the file it finds there, if not it begins searching down the
paths in that list.

In the menu, Tools->Options->Directories VC6
