so, this morning i wake up and turn it on from cold boot, usually i never turn it off but i did last night, and one of my drives was making a loud clicking noise. i freaked out and turned it off, opened my case, messed with them a bit.. reboot and no noise. goin on what i got from google, one of my hds is failing, or gonna fail soon, but as of now all data is fine. how do i find out which one it was and wtf should i do? ive made the .bkf for my c: just now.
