Hi, my internal 1TB harddisk will sometimes buzz and screen freeze for 2-3 seconds when i try to access to the files inside. Then after that, my harddisk will be normal again. Only after like a few hours later, it will buzz again when i try to access again. My friends say it is because i have too many files inside, so the buzz sound is harddisk scanning, but i m not sure is it true. So anyone have any ideas what it really is?
