I have a My Book WD5000H1Q-00 and when it’s connected via ESATA, the drive will spin-down after 10-minutes. When this happens, Windows is unable to find the drive.
I’ve made sure that Windows power settings have “turn off hard drive” set to never.
Other posts show that firmware updates resolve this problem on other My Book drives, but I can’t find a firmware update for this one.
Or is there a software solution that will keep my drive awake?
