I haven't tried..
But most USB powered hdd draw about 950ma -1000ma (1amp) so if your going to try it you will need a decent power supply preferably above 2.5 amp also you would need to edit your config.txt to include this line.
Code:
max_usb_current=1
The above sets the current output on the pi to 1amp rather then the default 600ma

This isn't something I would recommend or even guarantee it will work. The safest way would be to buy a USB powered hub and directly connect external Hdd into that.

I was doing it for a while and sporadically would get the low power icon and some odd errors here and there. Finally switched to a powered hub and it works fine.
