Power supply at my house is through a Stabilizer , which makes it fluctuate very often , So do i need to connect external hdd(Lacie HDD) power thru a UPS or the adapter provided with HDD will take care of such fluctuations??
No , Stabilizer simply maintains a voltage range say from 200-240 V no matter whatever is the input and doing that it can jump from 200V to 240V in a fraction of second.
