I used my external hard drive on my windows 7 computer to store my photos and videos. When I bought a new smart TV I connected the same hard drive to the TV and am able to view and play the stored content. The problem then arose when I reconnected the hard drive back to my computer. I now can not access my hard drive unless I format it but I do not want to loss what I have saved on it. The error I get is F:/"is not accessible. the parameter is incorrect" & "the volume does not contain a recognised file system. Please make sure that all required file system drivers are loaded and that the volume is not corrupt" I have run Disk Management and it shows the File System as RAW Status Healthy (Active, Primary Partition) I know nothing about computers but hope that someone will be able to give me an idiots guide to rectify this problem. I have tried Recuva & EaseUS data recovery software but nothing has worked. HELP
