use m3datarecovery to recover the files first...
this is one of the best softwares out there... http
/www.m3datarecovery.com/
but you need to get hold of the full version...
this is a step by step instruction... http
/www.m3datarecovery.com/data-recovery/online-help...
the method you should be looking for is..."How to recover deleted or lost partition?"....
it is towards the middle of the instruction page...
it says that i cant restore more than 1gb space but the files which have been recovered aren't opening, is there another way please help
once that has been done, clean format the sd through cmd...
