I'm a novice,not sure what I told you guys. Seagate drive came with disk.I cloned new disk with there program.Took out old drive,found i still had problem booting.Problem being:start up window freezes on logo for 1 min. then message comes up saying can't find pri.drive 1,can't find pri. drive 2,press F1 to continue which i do and computer boots.So my intention now is to format and do fresh install.WhenI right click on drive ,and click format I get message windows cannot format this drive. Hope this makes it clearer.Thanks for your help.
