Dying Hard Drive.. again

Hard drive dying... again.. well it's not the same drive as the previous one, at least it is of same brand. My Seagate ST3160827AS (wow i can actually memorize it already having checked the validity of the warranty which runs til 2010) has been showing signs of inability to read/write to the drive thus getting bad cluster errors and worst still the drive 'disappears' when chkdsk /f is applied to fix the drive. Oh and the problem started not long ago.. I guess last month it started to be this way and the rate of the bad clusters appearing is increasing neither constantly nor exponentially..

And this drive was bought in July 2005!!!
Preparing my RMA box soon as I get my new HDD (Hitachi here I come)
