I'm using Dell studio 1558 laptop with Windows 7 and 8 in dual boot.
I've 2 external hdd, WD my passport 0740 and Sony HD E1.
well in windows7, these 2 ex-hdd or any one of them doesnt go to stand by,
but in windows8, they go to stand by (stops spinning, indicator led goes off).
In both, windows 7 & 8, same time duration for "turn off hardisk after" are selected, and all other power options are same, I've checked.
Even i face the same issue with my windows 7 in desktop.
What should i do to make them go to stand by in windows 7 ?
