A customer just reset her Win 8.1 and lost all her files. She has hardly used it since this event, so I used Recuva,, which found 40 GB's worth of data.
But according to Recuva, it was almost all overwritten - mostly by drivers. I copied the data over anyhow, but it is all too corrupted to read.
I'm at a loss, because over 6 different operating systems, I have always been able to recover - at least something. How is it possible that an OS install that uses under 20 GB, could overwrite 40 GB worth of data. It's a big hard drive, and the odds against it would seem to be astronomical.
In fact, even the files (all PDF's) that Recuva claimed were not overwritten, would not open. (Though every item in the list did have a yellow light in front of it.)
I have had similar results with other software.
Am I doing something wrong? Did she accidentally reset it 2 - 3 times?
