That sure sounds like my 12 hours. I guess this more or solves the mystery. There is still one thing which keeps me wondering, though. How exactly does the ata driver react to the drive doing ADM? Whenever I hear it spinning down, I immediately hear it spinning up again. Does this mean that the ATA driver won't allow the drive to do _any_ ADM at all? Is that a bad thing?
