#Note: This example was created for modeling purposes only and is not a reflection of actual data or an existing implementation.
#Use case: Emory University acquired several hard drives as a part of the Rushdie papers. Imaging of the drives was outsourced to a vendor who used GNU ddrescue 1.19. Following receipt at Emory, a digital archivist reviewed the image, verified the MD5 checksum, and created a SHA1 checksum. Ewfacquire was used to migrate the disk image from .dd to .E01 in preparation for ingest into Emory’s digital repository. Individual files (including a Mac sticky note) were extracted from the image using FTK Imager and ingested as separate files. All ingested files undergo validation, a virus check, and checksum generation as a part of the ingest process. Users may view files in a emulated environment, which uses SheepShaver 2.3 on a Mac Powerbook. This emulated environment has been imaged as well and ingested into the repository for preservation purposes.
#The disk images are restricted to the public but the sticky note (an example of an extracted file) is available for reading room use only per the deed of gift.
