Hi, just a couple of days ago my external hard disk (1TB Samsung STORY) turned RAW. I've installed Revuca to recover my files but whenever I use it and select the drive which I want to recover, it asks me format my drive or it is inaccessible. I'm worried about my data as well. I'm not sure on how to use Recuva but do I have to format my RAW disk before I recover my files ? I'm confused, please help !
