1520 owners, in a quiet room do u guys hear the click noise coming from the hard disk randomly ? Mine is a toshiba harddisk... checked in the toshiba site telling its normal tat the hdd is making noise... are u guys' harddisk in ur 1520 making the asme thing ?
Yup, that's what happening to my 1520 too. Basically you'll just hear the clicking sound of the hard disk randomly. At first, I thought the hard disk is having problem because my fren's TOSHIBA laptop hard disk doesnt produce this kind of sound.
I've complained to DELL about the clicking sound (my first hard disk was SEAGATE)

. DELL then replaced one for me (it was a HITACHI), however the clicking sound persists.
But my bro's 1420 TOSHIBA hard disk is not producing any clicking sound

. That makes me wondering maybe it is just the 1520 which have this problem.
So, I think it is caused by the laptop sound proofing gua...guess only.
That's the kind of quality you get from such a low price laptop....
