Rockpi 4B external hard drive not found after warm boot

#1

Hi All,

I recently setup a small server at my holiday hosue using a RockPi 4B v1.3 and running Armbian. It has a 2TB 2.5" external hard drive and has been running fine for several weeks.

I recently added a second 2.5" portable hard drive and partitioned it fine, but after a soft reboot (ie sudo reboot), the new drive wasn’t found.

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 <>ASCQ=0x81

Any ideas?

After an unplug/reboot, dmesg shows:

One thought is that the USB3 sockets don’t provide enough power - the Radxa site 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

Any additional ideas?

Thanks,

Paul

What power adapter are you using?

#3

18W USB PD Power supply - https://www.amazon.com.au/gp/product/B08CCL5T17

#4

If you want to use two hard drive, change to a 30W or more power adapter.

#5

OK - I’ll order one now and install when I’m next at the holiday house.

OK so I changed over to a 30W USB PD power supply today, and still had no 4TB drive after a reboot.

Originally, I had both hard drives connected to the USB 3 ports. I moved one of them to a USB 2 port and now both drives seem to survive the reboot. The ‘working’ configuration is as per https://photos.app.goo.gl/frowcFeJCpDCjkGZ7

Did you get this to work?

i am having the same issue.

#8

Yes, per my post above yours, I moved one of the drives to a USB2 port and all has been good since.
