How do you power them down?
I don't know about the original poster, but my "noauto" disks
timeout and power down all by themselves, then even when they aren't
mounted at all, every time I reboot, the reboot hangs while it
spins up the disks for some reason. I constantly wish I could make
it stop doing that.
I suppose that the disks are always "on", even when they are not spinning.
At boot of course they will be scanned for partitions etc. so they will
spin up.
Then, they may have a timeout (in SATA firmware or USB firmware) to spin
down when not receiving requests, and that works for me even if the
filesystem is mounted (no process does anything on that fs).
This is why I was asking about the "manual shutdown".
It could be all entirely automatic and power-saving based.
Otherwise, I would like to know details.
Regards.
