Just got this WD40EZAZ (4TB). With four different desktop powersupplies I’ve tried, it will randomly restart/respin every once in a while, but mostly when I try to access it.
It won’t show the same problem if I connect it in an external Seagate FreeAgent disk enclosure using a seperate power adapter.
All other 4 supplies I’ve tried work great with all my other 5 hard drives, and the WD would fail with any of them even if it’s the only HD connected. Here are the supplies:
WD Data Lifeguard didn’t report any error.
Does the WD40EZAZ require a special powersupply? is it defective?
