Disk filter driver to prevent mounting of volume

NTFSD
1

Hi List,

I’m writting a disk filter driver for a security application. Currently I
have a seperate partition to store some of the data used by my application.
It’s a FAT32 partition and I’m trying to prevent windows from mounting it,
meaning I don’t want it to be visible from windows, even through the disk
manager.

Is there any way I can prevent mounting of this particular volume through a
filter driver?

Thanks,
Kelvin

Hi Kelvin,

You can take “sfilter” from IFS samples as a base for your filter and fail mount request when it comes for your volume.

The question is how do you plan to get to know that a certain FAT32 volume is yours?

Thanks,
Roman

One more way is to modify the type of your FAT32 volume in the partition table to any value, Windows (not tested on Vista) will not mount such a volume then.

If you will create a drive letter symlink manually - it will be mounted.
This is how the vendor’s (Dell’s or so) diagnostic tools partition work.
