you need a smooth surface, such as a cleavage plane in order to see the scratch. Remember that the hardness works the other way also. Try to scratch a piece of glass, if it leaves a scratch your hardness is at lease 6.
Have fun scratching up everything!

Depends what equipment you are using ...
Vinyl is very difficult. The best bet is to rig the deck up to a tape player or, even better, digitalise it and feed it into your PC.
If using a CD, simply pause the track in the right place, and then record it. Clean the sample up with software freely available on the net.
There are sites where you cann request the sample you want.
Hope that answers your question
