If you performed physical imaging (in other words, created a disk image), then we can use another CCA tool to do some initial steps to characterize the files within the image and also extract the files from the image.
CCA tools is run on BitCurator, a customized Linux operating system, that we run on a virtual machine through Windows. To access do the following steps:
Click on the Oracle Virtual Box shortcut on the Windows desktop screen
Virtual Box will open, click on the BitCurator with the latest version number after it
Wait for the operating system to load. Once you see a screen with a blue background, BitCurator is ready to use.
Open the “CCA tools” folder on the BitCurator desktop screen and click the Click the “Disk Processor” icon.
Processing tab
Archivematica is not the best for extracting and analyzing files within a disk image. We also want to know something about the files we are keeping and disk images can be opaque. For those reasons we will do some processing prior to Archivematica. The Processing tab also has the added advantage of creating a package that Archivematica can understand.
Choose the processing tab.
For the Source, select the folder where disk image(s) are stored.
For Destination create a folder within the folder where the disk image(s) are stored and name it the same as the parent folder. You can then move the folder once the package is created.
- Unless you have additional information to add to the metadata/submissionDocumentation folder, select the bag SIPs option.
- If you believe that you may not end up keeping the disk image, choose the “Make SIPs from carved files only (no disk image) option.
- Do not select the run bulk_extractor option. (This looks for PII and other restrictions, we will do this later with another tool.).
- Click the Start processing button.
- If you did not select the bagging option, add your submissionDocumentation to the metadata/submissionDocumentation folder within the appropriate SIP.
- If you have not already looked at the reports generated (i.e. did not use the analysis tab before), proceed to the Appraisal section for help with appraisal of the items. (link)
- If you have already appraised, proceed to the access restrictions section. (link)
Analysis tab
The actions performed by the analysis tab allows you to analyze your files to better understand what the contents are and for appraisal with the same reports asthe Processing tab. In general we do not use the Analysis tab and use the output from the Processing tab for both analysis and extraction (re-running it if necessary).
