Which acquisition is typically used on a powered-down system to preserve evidence and avoid altering data?

In digital forensics, preserving evidence on a powered-down system relies on creating a static image—a bit-for-bit copy of the storage that is made without booting the machine or running any of its software. This approach uses a write blocker to ensure no writes modify the drive, so the exact state of the data is preserved, including remnants, deleted files, and slack space. Verifying the image with cryptographic hashes and maintaining a clear chain of custody are essential to prove the copy is pristine.

Live acquisition involves imaging a system that’s powered on to capture volatile data like RAM and active processes, but it risks altering data and doesn’t capture non-volatile content in its original, untouched state. A hybrid method combines static and live techniques but is used when both types of data are needed, not solely for a powered-down target. Remote acquisition collects data over a network and isn’t the standard method for securing an unpowered device’s disk in a way that guarantees no alteration.
