Hi,

I have a new http://www.wdc.com/en/products/products.asp?driveid=552

Very strange, my Windows 7 rate my WDC http://www.wdc.com/en/products/products.asp?driveid=552

5.4!

Is it normal? or the shop cheated me?

And some more, when I first time turn on my PC, the harddisk is high pitch, and got clicking sound.

Is it normal?

Thanks
