The dd command utility is a simple yet powerful and useful command available in Unix and Linux systems which is used to convert and copy files.

In a terminal window type: dd if=/dev/sda of=capture.img conv=noerror, sync I am attempting to make an image backup of a Windows 8.1 Dell laptop. #USE DD TO CREATE IMAGE OF HARD DRIVE WINDOWS 8.1# Unix like systems treat all devices as files and these device files are located in the /dev directory in your system. So typically your hard disk drive is a file in the /dev directory with the prefix of hd or sd (depending on IDE or SCSI driver). It appears the Symantec Ghost 11 will not boot on this newer hardware. Virtual Hard Disk (VHD) is a disk image file format which represents a virtual hard disk drive, capable of storing the complete contents of a physical hard drive.It’s a container file that acts similar to a physical hard drive. * Where /dev/sda is the drive you are acquiring the image of and capture.img is the chosen name and extension of the acquisition file. The disk image replicates an existing hard drive and includes all data and structural features. The conv=noerror, sync switch ensures dd will not skip over any sectors and will be an exact copy. Also, when I do this I prefer to be in the directory of where the image file will be stored. In the following example I used dd to make an acquisition of my swap file. The first one is command line utility to capture Windows image under recovery environment or create ISO image (.wim) of hard drive in Windows 10/11 for deployment. *If you only need to acquire an image of one partion on the drive then specify the partition number with the disk. #USE DD TO CREATE IMAGE OF HARD DRIVE ISO#

It requires a Windows 10 recovery media or installation disk. #USE DD TO CREATE IMAGE OF HARD DRIVE WINDOWS 10#

While for the second one, its a way recommended by Microsoft, and you can use it to install or upgrade Windows. #USE DD TO CREATE IMAGE OF HARD DRIVE INSTALL# One of the most critical aspects of forensics is validating digital evidence. To maintain the integrity of the data collected, hashing algorithms are used to create a unique fixed length hexadecimal number base on the data set. The output is referred to as the message digest or the digital fingerprint.

Within Linux, md5sum and sha1sum can be used to validate your work. I prefer to use sha1 over md5 because sha1 uses 160 bit encryption as opposed to 128 bit, and has a higher resistance to collisions.

In a terminal window type: sha1sum capture.img > Hash.txt In a terminal window type: sha1sum /dev/sda > Hash.txt Collisions occur when two different files produce the same hash.
