I have a hard drive that is failing, at POST it says S.M.A.R.T. bad status and I've already downloaded the diagnostic tool from the manufacturer and ran the test..the test only lasted a few seconds and sent a message that it failed. So I just received a new Seagate hard drive and I was wondering should I wait to let my current hard drive fail and kill over or should I immediately swap out hard drives and do the fresh install of Windows 7 Prof. Or should I simply add my new hard drive onto my computer and clone the current hard drive and then format the bad hard drive..and maybe send it back manufacturer to restore it to good condition (just an idea).
