MAIN HDD is not loading anymore (I think)

[sixam.canoscan]

I was away from my PC (powered off) for about 30 hours (due to Harvey). I came back, powered it up...and it just crawled. I mean it took a good 30 minutes before Windows finally loaded. Then it struggled to do ANYTHING once in it. I have tried: Power Cycling, Cord Cycling, De-fragmenting (although it wouldn't let me do the affected drive), blowing out the machine, System Reset (it wouldn't let me complete this either). Right now it says that the drive is close to catastrophic failure and it won't even let me go past the BIOS. What is there to do? Is there anything to do?
