You might be able to boot "WinPE" on your MacBook. It's a Windows 10 "live system" that boots from USB flash drive. I have used it several times in the past to solve problems like yours, though I've only booted it on regular PC laptops/computers.Here I am again, postscript: WD does not have a Firmware Check/Update Tool for Mac! This is truly intolerable!
So:
- I don't know what firmware my disk has
- I won't be able to update it anyway
(unless I take everything apart, connect it to a Windows PC with a USB adapter, etc etc...😡)
