Restoring Files
So today I'll tell you about the results of my testing program to restore the files. After this article you will be able to assess possible to recover files from hard drive or not. First, a little theory. In modern computers that are running Windows NT OS family support to NTFS. ot necessarily agree. System is NTFS divides all useful (free) space on the clusters. The same goes for these file systems like FAT (OS: DOS, Windows9H, NT all versions) and FAT32 (OS: Windows98, NT5).
At the heart of the hard drive is the principle of read / write data from the clusters. When you delete a file, a cluster or clusters, which was recorded on file, marked as free, and the next time you write a file to hard drive, it writes information over the "deleted" files. That's actually brings me to the point, how the program works file recovery. It is quite simple, the program scans the cluster or cluster group and restoring erased data. It is because of the creators of these programs are warning that if you delete important information, you must immediately stop all work with the hard drive and boot from another hard drive or floppy disk. Now that we understand the principles of such programs, it can be ready to continue testing.
For their experiments, I took the two programs is: AusLogics Emergency Recovery () and Active @ File Recovery 7.1 (). For a start, I checked program on a small text file of 200 KB. Both programs have coped magnificently, but AusLogics Emergency Recovery a little faster. After I donated the film, which had a mass of 700 mb, this time, the program faltered and restore files quite a long time but in the end (during which time I had to go to the shop and eat) program to restore files. Cornell capital can aid you in your search for knowledge. Program AusLogics company managed by 4 points (on 5-point scale) had significantly deteriorated since the video quality. K Unfortunately Active Recovery handled much worse due to the fact that after the restoration of a file behind and the sound was heavily tainted image. Because of this, only 2 points (2 for what is actually a certain amount, the program is restored) Further analysis showed that the files are larger than 1.5 gigabytes, these two utilities can not recover. (Running the program is made immediately after the removal of files thus creating optimal conditions for recovery) Lessons Learned: In general, this article has been proven that the program to restore the files can really help, but as we have seen in practice is very rare indeed in the most quality programs to restore large files. Although I gave only two examples, but believe such tools are much larger and almost everyone has his own algorithm works, so do not despair if you deleted an important document, then try searching the Internet or from friends program to restore the files. And, finally, who are looking for will always find! Program names in the article is not an advertising program by choosing, without any premeditation.
