Compactflash custom filesystem

[chacham15]

Problem: I have a compactflash card with a custom filesystem (implemented in a hardware device). I want to take the compactflash card and insert it into a compactflashcard reader. Then I want a program to modify some data on the card. Therefore, the problem is that windows does not know anything about how the data is laid out on the drive.

What I would like is an interface which I call some function which retuns a handle to the device. Then I would be able to read and write to it like any normal file. Therefore, I can create an interface to the filesystem myself. Is there something like this? Is there any solution to my problem?

Thanks,

You can probably open the device directly with something like:


HANDLE hDrive=CreateFile(
L"\\\\.\\PhysicalDrive2",
GENERIC_READ | GENERIC_WRITE,
FILE_SHARE_READ | FILE_SHARE_WRITE,
NULL,
OPEN_EXISTING,
0,
0
);


Substitute the proper drive for PhysicalDrive2.
