hard disk not recognized on laptop

[Petrushevski]

Hi guys,
I will try to explain this.First i have Asus laptop N75sf and it comes with two hard disks Seagate ST 9500423AS each 500 gb.The one i use for storing documents movies etc. it is not recognized.But i can use the laptop because the other one is good and there is my windows installed.When i turn on my laptop the hard disk makes some noise more than usual but after a while it stops.Sometimes my laptop freezes completly and i cant move my mouse nothing.So what are your suggestions ? Did the hard disk stoped working ?or something else is the problem? My laptop is only 4 months old and it hadnt got any crashes like fell on ground or something like that, that can damage the HD.
Thanks in advance

It could be one of your hard drives is failing and that is the noise you are hearing. It's only 4 months old so if it was mine I would take it to the place I bought it from.

Even after 4 days it is possible that a hard disk fails. I suggest you take the HDD out and leave it in the fridge overnight. Then put it back and run a chkdsk /r on it. Maybe it revives. But I would ask Asus to replace it.
