Windows Server - Can't boot Windows - frustrated! posted in the Operating Systems forums; You might have got some warning if your BIOS has/had S.M.A.R.T enabled.
I have known hdd's die overnight, just like that.
More on SMART here: Active SMART - Hard drive ...
That site was just the first in a google for SMART, have a look in your BIOS to see if it supports it.
Best of luck Smit sorry it's not the ending you were hoping for.
