Last week i was watching 300 on my computer windows 7 computer. There was sudden fluctuation and my computer turned off. When again i turned ON my computer the drive from which i was watching 300 movie does not open. It says i need to format the hard drive before using it. My friend says i need to format the drive to use it. But as far as i know formatting deletes all files from the drive. I dont know how to access the files from that drive as it has my notes and seminars in it. I did not access that drive from past one week and wanna get the files which were stored in it.
