[badger]

Not sure where to put this post, admin feel free to move.
I am looking to fit an extra hard drive into my home PC, running vista, and i would like the extra drive to act as extra storage for photos videos, music etc. I have had a look on the internet and picked up some advice but further advice on pitfalls what to look out for etc would be greatly appreciated.
thanks badger
