I have a seagate 400gb (ST3400633A) and before it has made a squeaking noise and used to freeze in windows and sometimes when I started up the PC, it didn't recognize the HD . It doesn't do that anymore, but Now, a month later, for a week straight, its is completely slow, I can't download with bittorrent anymore, It used to take seconds to startup windows, now it takes a couple of minutes, and everything I do in Windows is just slowed down.
I ran seatools and it has passed the short and long test. But, my computer is still slow, and I still think it is the HD.
I need HELP!!!!, please help me figure out whats wrong.
