Mounting an internally installed disk on a laptop spins up all

Are the externally connected disks mounted?
/dev/sda: Device of type 'scsi' [SCSI] detected
/dev/sda [SAT]: Device open changed type from 'scsi' to 'sat'
/dev/sda [SAT]: Device of type 'sat' [ATA] opened
(On a side note: I'm astonished that a smartctl simple info flag is
changing some device type like shown above)
Not really strange. /dev/sd* used to refer to SCSI disks, so it starts
out assuming the drive is SCSI. After checking it, it determines that
it's actually ATA and continues accordingly.
