USB Hard Drive not recognised on warm boot

Question

Armbianmonitor:

I recently plugged in a 4TB Seagate Expansion hard drive and it worked fine.

 

After rebooting the Rockpi4B via 'sudo reboot'  the drive  is not recognised -  dmesg shows:

[    3.877060] sd 1:0:0:0: [sdb] Unit Not Ready
[    3.877082] sd 1:0:0:0: [sdb] Sense Key : 0x4 [current] 
[    3.877094] sd 1:0:0:0: [sdb] ASC=0x44 <<vendor>>ASCQ=0x81 
 

Any ideas?

power 2 spinning drives drawing to much power starting at sane time...

I considered that -  however  the RockPi  page states:

How much mA can i get from the USB 3 and 2 ports for charging or use a 2.5" disk?

The upper USB3.0 OTG has one dedicated current limit control which is 1.45A. The rest USB 3.0 HOST and the two USB 2.0 HOST share a current limit control of 3A together
