There is nothing new to report that I am aware of.
In some cases the use of file recovery software such as R-Studio, Recuva or Photorec may be helpful to recover some of your original files but there is no guarantee that will work either...however, it never hurts to try.
Important Note: The more you use your computer after files are deleted, encrypted or corrupted the more difficult it will be for data recovery programs to recover any deleted, unencrypted and uncorrupted data. The less that is done with the hard drive between the time of the data loss and the attempted recovery, the more likely it is that some or all of the files can be successfully recovered. The more the hard drive with the lost data is used, the less chances of recovery. This is because there is a greater risk that new data can be written to the drive, overwriting and destroying deleted files that could have otherwise been recovered. When you delete a file, its content physically remains intact on the media, but the occupied space becomes marked as free. The next file saved to the disk may overwrite the contents of the deleted file. Therefore, the sooner that data recovery is attempted after a loss the greater the possibility that data can be successfully recovered. It is also very important to make sure that no application (including the recovery program) writes to the drive or partition where the deleted file is located since every new file may overwrite the deleted file.
The chances of success will be greater if the drive is not defragmented and that you install and use a data recovery program on a drive other than the drive you want to recover files from (i.e. second hard drive, separate partition or USB flash drive) otherwise it could overwrite recoverable files. You could also "slave" the original hard drive and install the software on the new drive.
