Hello, 0602. :-)

Can you please post dmesg of a successful booting? That will tell us
which SATA controller/disks you are using. Also, the boot log of a
failed boot will be very helpful - the best way to get this is via
serial console. If you don't have access to serial console, taking note
/ picture of the part where SATA detection fails will do too.

Also, when the machine boots successfully, does it work without
generating disk related kernel logs? Just perform any IO-heavy
operations - cp'ing directories which contain large files,
tar/untarring... - and see if the kernel complains about anyting.
