Hard drive cable was spoilt. No longer under Apple warranty. Local shops were charging $200USD onwards, claiming they had to first verify the problem, despite me telling them I am quite sure it is the cable.
Very easy guide to follow. Got the whole thing working in 15min.
Don't need the spudger actually. Just use a ruler or something similarly flat :).
