I was backing up my C drive creating an image using Acronis onto my external F drive (format FAT) when half way through it showed an error. I shut down Acronis and clicked on the shortcut to my F drive thinking that I would delete the backup thus far created and try again. When I clicked on the short cut on my desktop to open the F drive suddenly it is telling me that the disk in drive F is not formatted and would I like to format it now. When I right click on the F drive it tells me that the file system is RAW and that there are O bytes used and 0 bytes free. Have I lost everything that I have stored on my F drive. I don't know what to do. Please, please help me.
