The drive I have been using as my primary is on its way to failure (I've heard the click of death and gotten SMART errors.. no question on this). I called for an RMA and I'm wondering what is best way to preserve the data on it. Am I better off turning the computer off until the new drive comes or will that have no bearing? Also, what is the best way to dump all data from one identical drive to the other for when I get my new drive (being optimistic that the failing one holds out)?
