I have 2 hard drives that share a motherboard (can only have one in at a time obviously) and my wife has pulled one out and inserted the other without shutting down first (DOH!). When she put in the second hard drive, nothing seemed to happen - at this point she panicked (?) and removed the second hard drive, again without shutting down. Then she tried to shut down and couldnt get the start menu to appear. So she turned the power off! When she switched on again, she is getting the message about FATs not matching. What do I do??? Apart from kill my wife?
