I keep all of my images (I'm a photographer) on an external drive. I was in the process of checking some unlabed data discs, (CD's) and inserted one to try to identify what was one on the disc. It turned out to be a restore disc for this PC. The next thing I know, it no longer showing up as "transcend", the 1 terabyte model I use. It is suddenly no longer labeled Transcend, but recovery. It appears not of the data in present. leaving no trace of the thousands of file stored there.
Any help appreciated,
