No. 

This is a guess, but I would guess that you may have screwed up your Boot.ini and/or your Ntldr (NT Loader).   

I would do a Repair Install of Windows to get Windows Back.   Here are Instructions on how to do a Repair Install.

Then once you get Windows Back, work on getting the Hard Drive Recognized.  I believe that you need to Enable Large Hard Drives, Maxtor has a Download on their website that you need to download and install.   Once you have that, I think it will recognize the drive fine.   Here's Maxtor's Website:  http://www.maxtor.com/
