This seems to be a case of disaster recovery. Disaster is just un-avoidable form of error.This cannot be avoided but some precautions can be taken. I think that, as this was due to a power fluctuation, there may be an effect in the working parts of the disk. You should consult a URL removed due to suspected spamcompany to get your job done.This can be very frustating and may be worthless if you try to get the data back by yourself and the situation gets worse.So better take the safe route and get the projects saved in a reliable way. All The Best!!!!
