analyzing-disk-images

Perform dead-disk forensics on an acquired disk image using The Sleuth Kit, Plaso, and bulk_extractor — verify integrity and mount read-only, map partitions, recover deleted files, build a file-system and super-timeline, carve unallocated space, mine registry hives and OS artifacts, and detect anti-forensics. Use when handed a .E01/.dd/.raw/.vmdk/.vhdx disk image or forensic acquisition to examine, recovering deleted files, building a file-system timeline, or carving artifacts from unallocated space.

# Analyzing Disk Images

A disk image is a frozen crime scene, and the whole discipline is preserving
that. Work only from a verified, read-only copy, prove nothing changed with
hashes at every step, and remember that the deleted and the unallocated often
say more than the live file system — because that is exactly what someone tried
to remove.

## When to Use

- You have an acquired disk image (`.E01`, `.dd`/`.raw`, `.aff4`, `.vmdk`, `.vhdx`) to examine
- Recovering deleted files, or reconstructing what was on a wiped or reformatted volume
- Building a file-system timeline or a full super-timeline across the whole image
- Carving files and artifacts out of unallocated space, slack, and free clusters
