Let's try to change it to active mode ... but failed!
sudo SeaChest_PowerControl -d /dev/sdb --transitionPower --powerMode active

All other states works! For example

Power State Transition Successful.
Please give device a few seconds to transition.
Hint:Use --checkPowerMode option to check the new Power Mode State.
Help seems explicit ... no clue why "active" not possible
Code:
--transitionPower
Use this option to actively change --powerMode. The available
power modes are idle_a, idle_b, idle_c, standby_y (SAS only),
standby_z, or active (SAS only).
Note: Hard disk drives require a few seconds time to spin up or
down. The drive will report the old power mode until it is
fully established in the new mode. The SeaChest --spinDown
command is similar. On SAS --spinDown is equivalent to Motor
Stop and --transitionPower --powerMode active is equivalent to
Motor Start.
Example: --transitionPower --powerMode idle_a
Example: --transitionPower --powerMode standby_y
interactive seems partly working, let's try to set some default behavior
sudo SeaChest_PowerControl -d /dev/sdb --changePower --defaultMode --powerMode idle_a

Failed to check if drive supports modifying power conditions!
ERROR: Could not change power mode settings.
Euhhhhhh?!
Totally confused by what I can or not do with this ....
I start to look at Power Consumption but I do not think this the right direction
Code:
--showPowerConsumption (SAS Only)
This option will show the power consumption rates supported by
the device and the current power consumption rate of the
device. Use a supported watt value with the
--setPowerConsumption option to set the power consumption to
that value.
--setPowerConsumption [default | highest | intermediate | lowest |
watt value] (SAS Only) (Seagate Only)
This option will set the power consumption rate of the device
to the value input.
Options:
default - sets the device back to default settings
highest - sets the active level to "highest"
intermediate - sets the active level to "intermediate"
lowest - sets the active level to "lowest"
watt value - sets the device to a nearest watt value
less than or equal to the value entered.
Power consumption watt values are listed with the
--showPowerConsumption command line option.
sudo SeaChest_PowerControl -d /dev/sdb --showPowerConsumption

Any expertise on playing with those Seagate USB desk expansion drives (powered usb drives)?
I have a simple NASCIE NAS drive with slave possibility, let's see if it manage it better (but will be slower as USB 2.0 and weaker CPU ....).
Last option is to set a NAS with a spare raspberry pi or power of my Nvidia tv shield ....
