Since I had to reinstall my computer once again, I also bought a new hard drive directly times. The Western Digital drive runs extremely quiet in my computer. I have not heard from the hard disk access. Would not the HDD lamp lights on housing often, I would say to the hard drive is not accessed. The speed of the disc is with me with 180 MB / s read and write more than twice as fast as my current plate. I highly recommend the Western Digital drive.
