Penta hat doesn't see any disk

#1

I’m trying to setup a NAS on Rock Pi 4b with a Penta hat. I run the installation script, but no drive was detected after it. Restart the service or reboot doesn’t solve the problem. The hard drives, cables, and the 12V power supply are all tested on a Raspberry Pi 4 with the Quad SATA hat and works just fine.

I can see the SATA controller on the PIC line using lspci which retures
01:00.0 SATA controller: JMicron Technology Corp. Device 0585

No disk can be found using fdisk -l or lsblk except for the EMMC. And of course no /sd in the /dev as expected.

Can someone advice what could be the problem? Did I miss any setups?

System information:
OS: Ubuntu 20.04 LTS (Rock Pi official repo)
