odroid HC2 - smartctl doesn't see WD red 4 TB

Armbianmonitor:

Hi all!

I am running a nextcloud server on an odroid HC2 and a 4 TB WD red HDD. So far, so good (thanks again @Igor for the quick help with the kernel downgrade!). And since I have bought the sbc recently, I do not seem to have the older firmware version with the HDD "emergency power down" bug, i.e. I haven't heard clacking sound from the HC2. Today, I set HDD spindown to 1 hour via hdparm (wd red does not support apm) because the HDD would spin down after about three minutes on its own. The HDD does not seem to apply these settings, so I installed smartmontools to check the HDD in general.

Only to find that:

smartctl -a /dev/sdb1

gives this:

To seems, it seems the JMicron USB-SATA Bridge prohibits armbian from seeing the actual HDD. Any way to fix this?

Thanks!

...installed the JMS Firmware upgrade to be on the safe side and it seems I did not have the current version. See output of smartctl -a /dev/sdb1 below:

Serial Number has changed, still no luck getting through to the HDD...

EDIT: solved it!
