Unfortunately in some cases is not possible to recover the data. Even with the most modern equipment, very extensive damages in the physical structure or the media logic can stop the recovery. In some cases, procedures or wrong attempts of recovery not executed by specialized companies or professionals, they result in the definitive loss of the data. Nowadays there is not any software market for media data recovery with any type of physical problems. Only after a detailed analysis it is possible to arrive to a necessary diagnosis, in which is defined the data that will or not be able to be recovered.
Observation: Even files that were recovered by other so called specialized companies, but presented problems for being in some way corrupted, they can still be reconstructed. If this is your case, although it is something more difficult to be done, we accept the challenge of trying to reconstruct your files.
