The weak link in all exteranl drives and video servalance is the power supply it is best to replace with 12vdc 3amp 4 amp is best
ive collected serveal NAS boxes and servalance recorders all needed new power supply only "Keep voltage " correct and always increase amp at least by 1 amp out to 4 amp raided will last longer
Always eject external drive no exception or power off system
Go to tiger direct or new egg for the best prices. Make sure that the power ratings on the new one is the same or higher than the old one.

i own the exact same drive. i'm looking for a spare power supply, came across this website, and saw your problem. the power supply is 12 volts dc at 2 amps. the connector that gets plugged into the hard drive: center pin is power (positive) and outer "shield" is ground (negative). hope this helps.
