Who has not, through negligence or omission, forgot to back up their photos before they format their disk drive? If hardware failure can be responsible for lost of data, human errors will be the main source of lost files. In this article I will be providing some good info on disk recovery and tips on how to make amends for your blunders.

Of course, if your HDD has been through a drop of 5 floors, or simply if it's not recognized in the BIOS, reading this post won't be very helpful. But if you just delete the pictures that you are certain to have saved on your hard disk drive, disk recovery software exists and should prove helpful to you.

To start, we'll explain why it is possible to undelete files despite formatting or deleting the trash. When you delete a file, you do not actually erase the data but merely eradicate the reference made in the index. The latter then considers that the disk space can be accessed again. Nonetheless it is quite possible to recover lost files by evaluating the surface of the drive. To make things more concrete, it's like finding part of a book devoid of the table of content. Although it might take longer it is possible.

This is why you need to avoid adding files, moving any folder or make any other manipulation that may use clusters previously allocated to your deleted file. Also you should not install any new programs in your hard disk to prevent any modification to your hard disk. However you can still set up new software on another hard drive such as an external one.
