Probably. On the power brick, it will tell you what the output voltage and amperage of the brick is. I'm almost certain it is DC power as that sure looks like a transformer.
You'll need to be sure you hook up the right + and - and that there aren't multiple wires or voltages that come out of the brick to the power cord. Probably aren't, but the plug into the drive has multiple pins. Those may or may not be the same voltage. Or, they may just be the output voltage split into different pins.
Use a multimeter to check everything and you'll be fine.
