I'm expreriencing a strange problem with an external SD card which has been mistakenly pulled out from the pc reader. About half of the files seem to have been lost because they do not appear in the explorer and neither in the properties. The strange thing is that chkdisk doesn't report any problem and it counts the right number of files.
Is there a way I can recover those? I'm running on windows 8 but have access to an ubuntu machine (in case there was some trick with it).
