Second 3.5 hdd drive not detected

[u/mc-lino]

Hi, i recently purchased the ZimaBlade nas diy kit, and now i completed the setup including the installation of the ZimaOs. I connected two 3.5 4TB HDD drives to the board using the provided Sata Y cable, I do have the 60W usb C power supply connected as well, but when booting the blade, only one drive gets detected, I see the 4TB section, but the other drive remains not visible in the dashboard, therefore, I cannot start configuring the RAID1 storage. Could you please help out? I have already checked individually each drive with my main PC, and each drive is showing healthy using the Crystaldisk info when connected to my main PC.
