I was installing Office 2007 and got an message saying it couldn't finish installing because of an error on the drive. I try to run scandisk and it won't run because the drive is being used. I schedule it to run on startup and it starts to run and then gives me an error saying it cannot run because of a recent software installation, please restore from a restore point prior to installation. I try to run the restore point and it says it can't because there is an error on the hard drive. I ran WD diagnsostics and it says the drive is passes S.M.A.R.T. I don't know where to go from hre. Any ideas?
