I am not sure, if ChatGPT knows anything useful about Sam460 LE + SiI 3132. Probably all text from GPT is pure fabulation.

Did you buy SiI 3132 new, or used? It is possible, that used controller was configured to RAID, and this not works for us. Test your controller on PC and check if configured to JBOD.
This is my screenshot of firmware screen:

In my screen is visible Sata device SATA2-3132, on your picture is missing. You have there only USB devices. It means, that firmware not recognized your device.
