Digital Forensics Hard Disk Data Acquisition: FTK, EnCase & Tableau TX1

Introduction

In digital forensics, forensic data acquisition is the most critical and sensitive step of any investigation. Whether it is a hard disk, pen drive, SSD, or external storage, the way data is acquired determines the integrity, admissibility, and reliability of digital evidence in court.

At Hawk Eye Forensic, we follow globally accepted forensic standards and use industry-leading tools to perform forensically sound hard disk and pen drive imaging, ensuring zero alteration of original evidence.

What Is Hard Disk Forensic Data Acquisition?

Hard disk forensic data acquisition is the process of creating an exact bit-by-bit copy (forensic image) of a storage device without modifying the original data.

This forensic image includes:

• Active files

• Deleted files

• Hidden data

• Unallocated space

• Slack space

• System metadata

The original evidence device remains untouched, while all analysis is done on the forensic image.

Why Forensic Imaging Is Important

• Maintains chain of custody

• Preserves original evidence integrity

• Ensures legal admissibility

• Allows repeatable and verifiable analysis

• Protects evidence from accidental modification

At Hawk Eye Forensic, write blockers and validated forensic tools are always used during acquisition.

Process of Hard Drive & Pen Drive Imaging

Step 1: Evidence Identification & Documentation

• Identify the storage device (HDD, SSD, Pen Drive)

• Document device details (make, model, serial number)

• Photograph the evidence

• Assign evidence ID

Step 2: Write Protection

• Use hardware or software write blockers

• Prevent any data modification on the source device

Step 3: Forensic Imaging (Data Acquisition)

• Create a bit-stream image

• Supported formats: E01, RAW (DD), AFF

• Generate cryptographic hash values (MD5 / SHA-1 / SHA-256)

Step 4: Hash Verification

• Compare source hash with image hash

• Confirms image integrity

Step 5: Secure Storage

• Store forensic image securely

• Maintain complete chain of custody records
