A fast and simple way is to use a pseudorandom generator with a specific starting seed.

What's a pseudorandom generator with a specific starting seed? where can i find the source or information about it?

A pseudorandom generator is a generator for fake random sequences. It's fake in the sense that as long as you use the same generator and the same starting seed (ie same initial state of generator), you can reproduce the sequence, so it's not truely random. Also, the sequence may repeat, but generally after a high number of repeats, depending on the code size.

There are many ways to implement a pseudorandom generator. You can google around for them.

The easiest way of doing this is using disk serial number which is unique.

you can get it using MSDN function "GetVolumeInformation".
