For an actual answer, it looks like WD has something called wdckit that is available on request.
I see a corresponding AUR entry that looks like it’s grabbing some zip from a personal Russian CDN. Super sketchy looking tbh.
But it’s possible this tool has whatever functionality the windows WD Utility uses to toggle the light in the drive’s firmware.
IMO, it’s not worth it. I’d just go the electrical tape route and maybe ask WD Customer Support if there’s a way, and if not, ask that they support Linux better in the future.
Also very windows like, aside from
Mount.
