HDDPhysic is a stand-alone component ( 32/64-bit Windows dynamic-link library - DLL ) that can be used to extract the physical vendor information from the computer hard disk drive, HDD (such as the unique serial number or model number).

The physical hard disk serial number is a unique number per hard drive device. If you want a way to identify your application user by generating a serial number for the computer currently running, this is the best approach because you can actually lock your application to the user hard drive by checking the serial number. You can find the actual physical serial number written on your hard drive, just have a look at the hdd labels if you have visual access to your hardware.
# HDDPhysic is a stand-alone component, does not require any other files to work.
# It uses the drivers on Win32/64 platforms so there are no special library/driver requirements.
# It can be used in any programming/scripting language that can make WINAPI calls like: Delphi, C++Builder, C#, Visual C++, Visual Basic, Visual Basic.NET, VBA, PowerBuilder, Visual Foxpro, Clarion and so on (examples for different development tools are provided for demo)
# Does not require administrator rights on Win NT/2000/XP/2003/VISTA/7
# HDDPhysic can also detect where windows is installed, on which HDD (See GetPhysicInfo function) .
