Hello I have got a Transcend 500Gb external hard disk. I use it in my laptop with windows 7 operating system. I have lots of data stored in it. I dint used it for three months as I dint required to access it. Yesterday when I connected my external hard disk and tried to access the drive I was surprised to see that there is no file or may be the computer is not showing the file. When I go to check the properties of the drive, it shows the used capacity and the free space. It means that the drive is not empty. I have some important file in it and don’t want to loose it. Please tell me what I should do.
