Data Restoration after IO Error on Hard Drive

“Hi, whenever I am trying to access data from a partition from hard drive on my computer, it is showing an error message; the message reads that the drive could not be accessed due to I/O device error. I have huge data stored in it. Upon asking others, all are telling to format the drive. But I have huge data stored it which I had been adding to the drive from very long period. Therefore I am not willing to format the hard drive. I am posting this here in the hope of getting correct solution. Thanks in advance...”
