/dev/hda2 not real but fsck thinks so

Here is a little story for you all: 
I went to work today and my housemate turned on my 
computer. Well, there was no work for me to do at work and 
my housemate calls me up right before I find this out and 
she says that as it was booting fsck stopped the proccess. 
I get home and it says that /dev/hda2 is invalid. There is 
no /dev/hda2 (only 1,3,and 4). I combined 1 and 2 and got 
of my Windows partition. What makes this even more strange 
is that I did this about a month ago; why is it 
complaining now? What do I do?
