Diagnostic tool for my Toshiba external USB drive trouble.
I just recently formatted my Toshiba external USB drive and stored new files in it. But after two days of using it, a problem occurs. When I plug my Toshiba external USB drive on my PC, it can be detected but it is empty.
I cannot find my files anymore which I currently saved. And when I tried to copy new files to it, a message appears that I have to format my Toshiba external drive first before I can use it. Does anyone have a diagnostic tool or solution for this problem?
