In which implementation of RAID will the image of a Hardware RAID volume be different from the image taken separately from the disks?
The correct answer is D. It will always be different. In a Hardware RAID implementation, the RAID controller manages all data operations - striping, parity calculation, and data reconstruction - at the hardware level. When you image the logical RAID volume, you see reconstructed, clean data. When you image individual physical…

Explanation
In a Hardware RAID implementation, the RAID controller manages all data operations - striping, parity calculation, and data reconstruction - at the hardware level. When you image the logical RAID volume, you see reconstructed, clean data. When you image individual physical disks separately, you see raw stripe chunks, parity blocks, and controller-specific metadata. These two representations will always differ regardless of the RAID level (even RAID 1 mirroring, where individual disk images may contain controller metadata not present in the volume image). This is a critical consideration in digital forensics: always document the RAID type and acquire images at the appropriate layer.
