I have same issue. Removed drive from affected PC, Deep Scanned and found thousands of recoverable files. I tried restoring to my HD, a network drive and also an SD card. They all show up great in Explorer but I get "device not ready" in every scenario. One other thing. The original computer apparently would not start and someone chose to restore from recovery partition (Lenovo) which it did and so in Explorer it shows a file structure for a new setup of Windows. The files needed were from drive before Windows got set up again.
