One of my HDD's tends to be grinding when in certain directories. I immidiately considered this to be a sign of an incoming failure and am about to head off to back up all my data off that drive. Before I got around to that, I ran both Seatools (I have a WD HDD but Seatools is compatible) and Data Lifeguard Diagnostic which is for WD drives (And supposedly others) and all test were sucessfull with no signs of failure. The Data Lifeguard Diagnostic had to do a 2 and a half hours long scan of all sectors of the drive and the result was perfect. I'll continue on to backup my drive but I'm just curious if I really should be worried? As I said it's only in certain directories: My One Piece folder is neatly organised into each arc and only two of the arcs cause a crazy amount of LOUD grinding. (There are also other directories) When the drive grinds, it tends to take a VERY long time and basically any of the files in that directory aren't available for use.
