The mA figure is the amount of current drawn from the supply by the drive. As you observe, the one you're thinking of using as a replacement does draw more current than the orignal however the current stated will be a maximum - it won't be taking either 500 or 700 mA continuously. My feeling is that it would work perfectly fine but, of course, no guarantees!
i think u first need to check the compatiblity with systemboard.
and the difference is when you calculate the power s
5v x 500mA = 2500mW
5v x 700mA = 3500mW
see if the outlets from systemboard to the HD in the power range!
Or, you can connect it directly and what is happen :idea:
i think that where my problem was. it drawns more power to the supply, an overload may happen to the chip responsible to sustain the required wattage.
actually i've already plugged this harddisk on one laptop, it was a disaster, :o after i have installed the OS and other softwares in about 2 hours, suddenly there was a "tick" sound and smell of burned IC.
i opened it up and i've found that an IC on the motherboard, near the interface of the harddisk was burned. i was thinking if it was just a coincidental and that the burned chip was really about to break.
Oh dear, it does sound like that is what happened. Is there any identifying data on the dead chip? If you're lucky it may just be a voltage regulator or something you can replace if you're handy with a soldering iron
i don't think that it could be repairable. i cant read the label at all, even i am able to desolder it, the problem of availability of the parts comes next.
i am very regretful for what had happened because of my dumbness.
and also to confirm if it really dumbness or coincidental.
