I’ve updated the firmware as per the instructions on http://www.wdc.com/wdproducts/wdsmartwareupdate/Step1.asp?pid=070C&os=MAC .
I am surprised that this is a cumbersome 2-stage process for the firmware and software update, but I’m only doing it because I’m hoping that is will enable me to disable it!
However, I’m shocked that the firmware update part requires a system restart. Why would it ever require the Mac OS to restart is beyond me. And this is not mentioned on the above page.
WD, your hardware is great. Your software is appalling.
