psmedley Posted December 30, 2021 Share Posted December 30, 2021 Armbianmonitor: http://ix.io/3K6K 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? 0 Quote Link to comment Share on other sites More sharing options...
Werner Posted December 31, 2021 Share Posted December 31, 2021 What happens if you disconnect and reconnect the hard drive? 0 Quote Link to comment Share on other sites More sharing options...
psmedley Posted December 31, 2021 Author Share Posted December 31, 2021 I'll confirm tomorrow (the drive and system are installed at our holiday house, 50km from me) - I'm 99% confident it will work. 0 Quote Link to comment Share on other sites More sharing options...

Werner Posted January 2, 2022 Share Posted January 2, 2022 Not sure but I might have had similar issues on restart but do not know anymore with which board. Anyway hard to tell what's the cause for this... 0 Quote Link to comment Share on other sites More sharing options...
psmedley Posted January 2, 2022 Author Share Posted January 2, 2022 Interestingly, there are two hard drives connected - a WD 2TB drive and the new Seagate 4TB. The WD 2TB survives the reboot no problems. 0 Quote Link to comment Share on other sites More sharing options...

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 0 Quote Link to comment Share on other sites More sharing options...
psmedley Posted January 4, 2022 Author Share Posted January 4, 2022 I asked Radxa - they advice a 30W USB PD power supply is needed to power two hard drives - I currently only have an 18W one. I've ordered a 30W power supply and will replace it ASAP and report the results. 0 Quote Link to comment Share on other sites More sharing options...
psmedley Posted January 9, 2022 Author Share Posted January 9, 2022 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 0 Quote Link to comment Share on other sites More sharing options...
