The logic inside the chips can assume nonsensical states that mean nothing. The only thing that means anything is the presence of the message(s), indicating that the HD isn't getting enough power to properly operate. The real risk is that in the process of scrambling, the hard drive logic may randomly fire the write head. This could occur anywhere, since by definition, the logic is illogical during an undervoltage. It could fire during a random head movement, between sectors or on top of valid data. If you're lucky, the hard drive only needs reformatting. If servo information gets wiped, the drive is toast. This is something to avoid if at all possible.
