sd error when i extract the sd and put in the pc everything i had in the sd card was gone and i could not open the sd card which it's name was change after that i format the sd card and it work 100% but....... is there a way to recover these files?
Actually it depends on the format, if the Windows quick format is used files can be recoverable (the files are still there, but the file table dosn't have them) Using a program such as Undelete Plus (freeware) you may be able to recover some files. However the fact your SD card crashed means there is little chance of anything being found.
