I seem to be the only one over the planet to get this problem, as I spent 1,5 hours to find a solution and I couldn't even find a question...
One of my Sandisk SD Card has a strange behaviour. It's used in my Nikon camera. It works there flawlessly.
However when I insert it to a SD Card reader (tried three computers with different reader manufacturers) the drive letter disappears from Windows Explorer. I then look for it the Drive manager: it's recognized (size and name) but with no drive letter.
So now I try to assign a drive letter, I click... and I get the following error message: "The specified file cannot be found" (sorry , translated from french). Same on the three Windows computers.
Using Recuva I could get the files back from the card, no problem. It's just a problem of assigning a drive letter I guess.
Any clue on what's going on? I may be an experienced Windows power user, but that one got me stuck... Thank you.
