I believe there is a config option (command) that will change ATA disks
such that they subsequently require a command to start.  i.e. they power
up in the powersave mode,  and need the normal 'leave power save mode'
command to get them going.

Though I also believe the command (feature set subset if I recall) is
optional anyway.

(I spent too long working on ATA disk drivers ~ 8 years ago)
