What should we do when format the hard disk by accident? I did not think those lost files could be restored in the past, but I know how to get the losses back now. I accidentally formatted the hard disk on my iPad three days ago and became upset; because there are useful files saved on it and had been lost. But one of my students told me that I can get them back, here is his way: At first, download and install the data recovery software on my iPad. http://www.ucfix.com/data-recovery/data-recovery-after-format-software.html Secondly, open the data recovery tool and choose the recovery model and aim disk to scan. Thirdly, wait some minutes and preview the recoverable files after the scan and pick up the needed to recover. At last, choose the location to save the retrieved contents. It is better to not select the formatted hard drive. And now I have get what I need back from the formatted hard disk.
