After scanning a hard drive (designated L:) that I had previously quick formatted I selected 61 files to recover from the list that was generated. I clicked on the 'recover' button and made a new folder "recov" on C: drive. I clicked 'OK' and for each of my selected files I got the message: "The following files were not recovered (61 total) The device is not ready. I tried again using a thumb drive for the receiving location with the same results. Both C: and the thumb drive are operating correctly. What's going wrong?
