I have an IRiver T10 MP3 player. I recently deleted a file and would like to "recuva" it, but when plugged in thru USB port it does not show up on the Recuva screen. It does show up on "My Computer" with all the files, and I can move them around, but Recuva isn't finding and listing it for a search. When I plug in an SD card it shows up fine, but not my MP3 player. Help???!
