For security purposes I need to locate a additional hidden partition on USB flash drive. The USB drive contains a security application that will check (in code) if the hidden partition exists. If not I will assume that the application is a non valid copy.

Any idea about it? Thanks in advance.

EDIT: There is already a programmed secure method to check if the USB drive is correct using the WMI Win32_drive class. The idea is to locate the drive info into the hidden partition and to check if it correct for anti-tampering procedures.
