If you have a bench power supply you may inject 1 Volt into both rails to see what they actually draw in current. Depending on how shorted the caps are, you can also detect the one that's shorted by putting a dab of alcohol on them. The shorted one will evaporate quicker.
You may increase the voltage if you need a higher current draw to notice the component getting warm, but as you never really know what its shorted with exactly I never really recommend going too crazy. 3.3V would be my max, and that should be way more then enough to detect the failing cap (Also you don't want the drive to actually boot up)
Obviously remove R45 before trying this to rule out the resistor, it has to be removed either way.
Also not entirely convinced it says 1 Ohm instead of "10", although you're probably right.
