Situation - Failed MBR on windows XP Professional
I have a Production PC (Manufacturing equipment controller) with Windows XP Pro that resides inside a turret (yes, this pc spins in circles 23 hours a day). Anyway, it's a vital piece of equipment for our manufacturing line. About every 18 months we have hard drive failures that lead to disassembly of the equipment to remove the PC and change the hard drive out. I keep 2 spares (imaged) at all times for just this problem.
Recently (this weekend due to our Ice Storm that blew out power repeatedly) we lost the drive in the middle of production. I removed the PC and swapped the drive so we could continue to run. I have just pulled up the hard drive on my PC (Windows 7) to check its status and it seems fine.... My guess is the MBR was corrupted from the repeated failures from power.
So, Is it possible to reconstruct the MBR in this drive as a it's a slave drive on my machine currently? If so, what file am I looking for to edit?
