I don't know what happened. I have to Hard drives Drive (C) is my master drive and Drive (F) slave. My (F) is just for space. I was working on my computer the whole day and when I tried to access some folders on my (F) drive it says that the folder was corrupted (can't remember the exact frase), it said that to all of my folders in this drive. I restarted the computer. Tried to access the drive now it says This drive needs to be formatted do you want to proceed. Is there anything I can do to recover my data on this drive because it is a lot of data. I did a system restore but nothing. Please help.

There are many softwares available although most will not work on a mechanically failing drive.

Also if your data is that important there is probably a local shop in your area that can handle this.
