itunes on 2 hard drives

[aljohn]

Hope this is the right forum. I have my iphone 3g synced to my desktop.. The hard drive is full of rubbish and slow so I fitted a new drive and os. I installed itunes on the new drive but I can only sync to my original drive. Is there a way round this? I want to use my old drive as slave until I've moved anything I want to keep to the new drive, then wipe it. If I can use itunes on the new drive I cann delete the original. Basically, I don't want to lose any of my stuff.
