Does anyone know of a good HDD diagnostics tool? I'm suspecting some Harddrive failure going on one of my 500GB 7200rpm sata drives, I'm about to install the Seatool (My HDD is a Seagate that I suspect). I installed a game on that harddrive and on my newest one, I notice a huge difference in loading, and other things, so I need to see if I need a new one

lol it has over 20k hours of use, i swapped it for a 500gb WD

lock is fine
