Is there anything I can do with the 6-pin connector-type-thing to the left of the USB-C?

My 5TB external HDD is no longer recognised by any computer I've tried. It spins up when plugged in via USB-C and I see it registering on my Mac's system report… but nowhere else (disc utility, finder).

Thanks in advance, hivemind!
