The normative procedure of evidence collection is physically isolating the computer when first time of touching it. Then the forensic experts create the imaging files from the original drive in order to analyze the copies to avoid any influence to raw materials.
In order to analyze the data found on the hard drive, they used a variety of techniques and data recovery software to find any hidden or recently deleted files and folders. The types of evidence that can be obtained through data recovery software include documents, videos, photos, messages, audio, and even Internet search history of criminal suspects. One of the basic techniques used by computer forensic investigators is to scan and identify and delete files and folders that occupy the computer. Then, they will try to recover the data in these deleted files and often find valuable data that can help file a lawsuit against the suspect.
•Fully support systems in NTFS, FAT16/32, exFAT, EXT2/3/4, HFS and HFS+, etc.
•Support PC, laptop, USB, SD card, CF card, TF card, Memory Stick, voice recorder, web server, IPC, surveillance recorder and diverse virtual storage file, as well as hexadecimal view. The supported format includes DD image(as well as mobile phone image), EO1 image, ISO image, etc.

Just like any other digital forensic process model, log forensics is a discipline that takes practice.
data loss can make a forensic analyst’s job harder, and without the proper hard disk recovery tools, you can quickly find yourself dead in the water.
Reliable data recovery systems may be the only chance the law enforcement agencies may have at uncovering such high-profile crimes.
