Accidently erased drive E or 5th partition, help!

Well, I was using Xplorer360 and while trying to overwrite a folder the program crashed and took my E drive with it. Now the xbox won't boot into the dash at first, it will display the splash screen and then go blank. If I open and close the dvd it will go to the dash then, but my hard drive shows 0 bytes. Also it will not play games.

I did make backups of the drive before this happened, but I never had the chance to backup my eeprom. I've already went over unicron's tut on how to extract the eeprom information, and will be getting the parts I need tomorrow. Seems like I remember reading somewhere that I need the info to rebuild my drive.

What I'm looking for is the information to rebuild the drive on an unmodded xbox. Any and all help is greatly appreciated.
