Mount and Verify a Disk Image

Prepare the working basis

Use a training image or a verified working copy; protect the original. Record the case reference, image path, format, byte size and SHA-256. Note the analysis workstation time and AIM version before mounting.

Prefer read-only for examination

Select Disk device, read only for browsing and evidence recovery. Export files to separate controlled storage. Do not select a mode that writes to the original image.

Select the image

Open AIM as administrator, select Mount disk image, browse to the approved working image and confirm that its identity matches your record. The preserved SUSA example uses a Windows virtual disk (.vmdk).

Choose the mount mode

In Mount options, select Disk device, read only. Review sector size and other options without enabling changes that are not required by the case. Note that BitLocker-protected volumes may need separate authorised handling.

Inspect and record volumes

After mounting, record every drive letter and volume AIM exposes. In the SUSA example the Windows volume appears as F:\. Browse only as needed to answer the investigation question; opening files may affect workstation-side metadata but should not write through the read-only mount.

Record the mount. Retain image path, mode and assigned drives.

Inspect the volume. Export evidence to separate storage.

Unmount and verify

Close applications using the mounted volumes, select the mounted image in AIM and choose Remove. Confirm its drive letters disappear. Recalculate or confirm the working-image SHA-256 according to procedure and record whether it matches the pre-mount value. Preserve errors, forced removals and unexpected write activity.
