The entire dilemma started a week ago when my 5 yrs old Seagate 7200.11 500GB crap out. I lost 90% of data. Good thing is my PC has 2 hdds. Second hdd is wd black 1.5tb which I bought in 2011 to expand storage. So i went ahead and used my WD to install system. Things runs fine for 3 days. Until this morning my PC again refused to boot up like normal. It took almost 20 mins to boot up. HDD activity light was constantly on. But I cant hear the drive operating like usual. When it finally boot up. I couldn't access one of my volumes on the HDD. Used HDTunerPro and get a SMART warning of "Current Pending Sector" The value is 15. My system is super slow. So my question is, how can both HDDs fail at about the same time? Or is it my power supply that is failing which caused the HDD problem? For the SMART warning, should I RMA the drive? Is "Current Pending Sector Warning" fixable or unfixable? Thanks guys!
