The Hex Value Interpreter converts this to 94 decimal, which means the data of the picture fills 94 clusters. The next 3 bytes 0 x AB A4 7B show the number of the cluster. The Hex Value Interpreter converts this to decimal.Encase Forensic is the most widely known and used forensic tool, that has been produced and launched by the Guidance Software Inc.

Encase is embedded with a variety of forensic functions that include attributes such as disc imaging and preservation, absolute data recovery in the form of the bit stream, etc. In this series of humongous applications, when Encase is used for creating backup i. This ". The concept of the E01 encase image developed by the Encase software came into existence as a result of efficient efforts by the Guidance Software to assist forensic investigators, analysts, and forensic scientists in finding an organized and systematized data for investigation.

The E01 Encase Image File Format file keeps backup of various types of acquired digital evidences that includes disk imaging, storing of logical files, etc. When an investigator or a Forensic Expert uses Encase to create a backup of data available in the hard disk, a physical bit stream of the data is produced.

This procedure is known as Disk Imaging. The basic theory behind the relation between the Encase and E01 image file format is that, while creating images of the data available on the hard disk, Encase divides the complete data into MB of data chunks.

Due to this division of data at the pause of MB, multiple data files, storing crucial hard disk information, are created.

The most peculiar feature of these files is that the name of the files remains the same as named by the user whereas the file extension changes. The footer of the E01 file contains an MD5 hash value of the entire imaged data. At the time of the disk imaging, the user is required to enter these details into EnCase. This information includes:. CRC is an error — detection code used by the Encase in E01 files to check for any accidental changes in the original data.

CRC is basically a hash function.

A CRC code for each data block is created by the software at the beginning of the acquisition and stored. Later, when that particular data block is scanned, the CRC code of the resultant e01 encase image is calculated again. If the new calculated CRC code and the previously stored CRC matches, then the data block is error — free else, some data error has occurred. CRC checksum is interlaced at every 32 KB notch of data. In these, data chunks, the data is divided into blocks of 32 KB and CRC checksums are embedded between every data block, to check for the occurrence of any kind of error.

This MD5 hash value of the raw image file can be checked and compared with, the MD5 value of the same image file created by any other third party tool. If both the MD5 values match, then no modification has been made in the original disc image file.

Otherwise, the file has been tampered or modified. This E01 file is a very important source of disk imaging and has now become a very peculiar and advantageous medium for forensic investigators to backup the data available on a hard disk that may later be examined and analyzed. Name of the Person or the Investigator Case Name in relevance to the actual case Description of media the configuration, etc. The operating system installed on the acquired device.Many computer forensic examiners utilize the E01 forensic image file format to store bit for bit copies of hard drives used in their examinations.

It is the default imaging option for many computer forensics tools and has become a defacto standard of sorts. While somewhat lesser known, the raw image file format also produces a bit for bit copy of the contents of a drive. This format is often referred to as the DD format due to the tool which originally generated such images. There are two main differences between the two formats. First raw image files do not contain any metadata.

They are simply an exact raw copy of the original data. Secondly, E01s natively support compression which typically results in a much smaller image file size.

At face value, E01 seems to be the superior format. Think for a moment about a typical computer hard drive that might be subjected to computer forensics examination. Among other things, an examiner is likely to encounter two things: free space and compressible data high quality pictures, videos, etc.

Now consider what is typically contained on a hard drive from a DVR.

First, there is usually little to no free space. In addition, the data recorded is heavily compressed with lossy technologies like H. Lossless compression the type used in E01, ZIP, and many other applications does a great job of offering the ability to save space while being able to recreate the original data exactly.

There are two issues, however. This will mean less performance. This particular hard drive was utilized in a real world DVR and was entirely allocated full. This is one of the fastest spinning disks on the market, so your results may vary depending on your hardware.

The imaging process completed in about 1 hour and 27 minutes. The search process completed in approximately 1 hour 53 minutes. The destination hard drive was formatted between tests in order to avoid any possible effects of fragmentation.

The imaging process completed in 1 hour 24 minutes. With no compression, the resulting image was obviously GB. The search process completed in approximately 1 hour 6 minutes. That was just on one search, so if you are doing a lot of analysis on this data, that performance increase can really make a difference over the course of the examination. Segmentation whether in E01 or DD format does introduce some amount of overhead. Your email address will not be published.

E01 Encase Image File Format is the file format used to store the image of data on the hard drive. It is necessary to understand about the file before understanding the process to mount E01 in windows.

It is the file that maintains the backup of different types of digital evidence such as disk imaging, storing of logical files, etc. However, a physical bitstream of the data is produced when a forensic expert or an investigator uses EnCase to backup the data stored on the hard disk.

This process is commonly named as Disk Imaging. In order to better understand the relation between Encase and E01 image file format, create an image of data available on the hard disk. Further, Encase divides the complete data into the chunks of MB data due to which multiple data file are created. However, the name of files remains same but the file extension changes, for example, S E01, S E02 and so on.

It means the file extension gets changed after exceeding MB limit without affecting the internal structure. As it is important from the forensic point of view and produced by the Encase Forensic Tool, therefore, it becomes the necessity of an investigator to mount E01 in Windows to open it.
