Hi,

I want to create a program that will allow me to store files on a partition that has a custom file system, the data is sensitive so I need a way to prevent anybody accessing it. Can anyone point me to some info about direct disk access under windows.

thanks.

If you want to protect your data, use the security functions built into Windows. If you're using a version of Windows without security (95, 98 or Me), direct hard disk access is all but impossible anyway.

Hi,

The problem is that even though it is very strong, windows services can be cracked! Quite easily with the right tools. I want to create a unique system so that noboby has even a chance of cracking it, because they will not understand it.

thanks.

The security Windows provides cannot be cracked, providing you set it up correctly (I'm thinking file encryption in Windows 2000/XP). What you are intending to do is security based on obscurity: "if they don't know it's there, they can't see it". Any administrator can see the raw contents of a volume given the right tools. However, no user -- not even an administrator -- can recover the contents of an encrypted file without the right key.

No user can see a file that they don't have read permission for, either. If they have physical access to the computer they can boot from a disk containing a DOS NTFS driver and read protected files, but not encrypted files.
