What is the primary difference between physical and logical acquisition in forensics?

The primary difference between physical and logical acquisition in forensics is that physical acquisition includes the entire disk image, capturing all data present on the storage medium, which encompasses not just active files but also deleted files, system files, and unallocated space. This comprehensive approach allows for a complete and thorough analysis of all data remnants that may be critical for investigations.

On the other hand, logical acquisition targets specific files and folders based on the file system and presents the data in a more manageable format, often omitting data such as deleted files and unallocated space that might not be directly accessible through traditional file browsing methods. This method is often used when the investigator is looking for specific information and less interested in the complete disk image.

In summary, the distinction lies in the breadth of data captured; physical acquisition is all-encompassing, while logical acquisition is selective. This understanding is crucial for forensic professionals who need to choose the appropriate method based on the requirements of their investigation.
