HDD gets not detected after reboot

[dkryder]

can  you mention the usb to sata interface chip you have? also, have you or could you try as a test if the issue exists on the usb-2.0 ?

I tried two different usb to sata interfaces from Inateck. Is it ok to post a link?

this one and an older one.

I have not the option to use USB 2.0
I need USB 3.0, but I will try it later.
If it would work with USB 2.0 would it change something?

Edit:
Wit USB 2.0 it gets detected fine...

that is why i asked you to test, to get better idea of issue. so we know that the hardware[hdd] is fine, at least the usb 2.0 interface. but now issue is with the usb3.0 circuit. i know of earlier issues with some of latest images.  you mention latest builds of xenial, some of the latest did have problems reported before. if you could locate the last  RELEASE version of xenial and try that. i do not have a link but search for  rock64 ayufan xenial RELEASE  or similar either on google or here, to locate the last release, the latest builds are more like alpha/beta builds and are not official releases, was built late last year i think but it has the fewest bugs. so try to find that and check if it will work with usb3.0. if not then log into the chat rock64 channel [the link is at top of page] and ask for ayufan or one of the other devs to help you out. i've not the additional knowledge to take the process to solution. if anyone asks tell them it has ASM1153 chipset.
