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?
