You can't do this with any certainty unless you are able to correlate the time of the failure with a power surge with hardware damage, which may be unlikely.
It is also possible that the problem was a software fault induced by the sudden disconnection of electricity, rather then a hardware problem. If SMART comes up clean and you boot off a Linux distro and run a badblocks test it may tell you more about errors - but be careful as it can also erase data if issued incorrectly.
You may also be able to pull a log from S.M.A.R.T which could correlate the status of the an error with the drive. I suspect that might be unlikely here though.
