Iomega Disks

Before a media object can be imaged it first must be recorded SPEC.

This section covers imaging with FTK Imager. Iomega disks are usually imaged with FTK Imager. Use FTK Imager when creating a disk image of a hard drive or removable media.

Using Digital Archives scripts

Make sure the setup instructions for Digital Archives scripts have been completed before running the scripts in the next section.

Create destination directories

These instructions show you how to create destination directories for a number of consecutive disks. Consider using a one-line command to create directories if the disks you are packaging do not have consecutive MediaID numbers.

On Mac:

  • Open Terminal.

  • Navigate to DigArchDiskStation.

  • Change into diskImages directory.
    $ cd /Volumes/DigArchDiskStation/Staging/ingest/diskImages

  • Create a directory for your collection if it does not exist.
    $ mkdir M1111

  • Change into your collection directory.
    $ cd M1111

  • Run makesips script to create a consecutive number of submission information packages for material from digital media.

Or

  • Change to diskImages directory.

$ cd /Volumes/DigArchDiskStation/Staging/ingest/diskImages

  • Enter mkdir command.
    mkdir -p CollID/Media-000{1..9}/{metadata,objects}
    mkdir -p CollID/Media-00{10..99}/{metadata,objects}
    mkdir -p CollID/Media-000{1,5,7,9}/{metadata,objects}

On Windows via WSL:

  • Open WSL.
  • If you do not see the Y:\ drive in /mnt or /mnt/y appears to be empty then it must be re-mounted by:
    • Changing to the top level directory by entering cd ../
    • Entering the command sudo mount drvfs Y: /mnt/y

  • Change into diskImages directory.
    $ cd /mnt/y/Staging/ingest/diskImages

  • Create a directory for your collection if it does not exist.
    $ mkdir M1111

  • Change into your collection directory.
    $ cd M1111

  • Run makesips script to create a consecutive number of submission information packages for material from digital media.

Or

  • Change to diskImages directory.

$ cd /mnt/y/Staging/ingest/diskImages

  • Enter mkdir command.
    mkdir -p CollID/Media-000{1..9}/{metadata,objects}
    mkdir -p CollID/Media-00{10..99}/{metadata,objects}
    mkdir -p CollID/Media-000{1,5,7,9}/{metadata,objects}

    Directory structure

  • /M2319-0021
    • /metadata
    • /objects

Image disks

  • Connect the Iomega drive to the FRED’s Tableau Ultrabay. See Using Tableau Write Blockers for instructions.

  • Start FTK Imager from the FRED’s launch bar and select Create New Image from the application’s file menu.

  • Select Physical Image and click next.
  • Select the drive to be imaged from the drop down menu and click finish.
  • Select E01 form the image type menu and click next.
  • Type the collection ID in the Case number field, the media ID in the Evidence number field, and your name in the Examiner field. Click next.
  • Using the browse button, select the objects folder in the correct collection directory (e.g. Staging/ingest/diskImages/M1111/M1111-0004/objects). Enter the media ID into the Image Filename field. Ensure that the image fragment size is set to 0 and the compression field is set to 9. Click finish.
  • Ensure all check boxes are checked and click Start to begin the imaging process.

FTK Imager will approximate the time needed to image the media.

  • Make sure that the checksums match on the complete screen, if not imaging was not successful.

Tracking

  • Navigate to the Tracking folder in Google Drive.
  • Find the spreadsheet for the collection that you will be working with.
  • Copy Tracking_TEMPLATE to create a spreadsheet if one doesn’t exist.
  • Name the spreadsheet the collection ID of the collection that you will be working with.
  • Check the media ID for the disk you are working with (for example, ACQ_11111_4444).
  • Media IDs follow the naming convention ACQ_acqID_specObjectID.
  • Enter acqID in the ref_acq_id field.
  • Enter specObjectID in the object_id field.
ref_acq_id object_id
11111 4444
  • Enter item in the type field.
  • Enter digital carrier in the format_1 field.
  • Enter Zip disk in the format_2 field.
  • Enter Zip disk size in the format_3 field. (for example, 100 MB)
type format_1 format_2 format_3
item digital carrier Zip disk 100 MB
  • Enter failed in the notes.transfer field if imaging fails.
notes.transfer
failed
  • Enter the filesystem format in the notes.transfer field if that format isn’t recognized by FTK.
  • Amiga, ProDOS, CPM are formats not recognized in FTK. (Unrecognized formats less likely for Zip)
notes.transfer
Amiga
  • Enter a note in the notes.transfer field if there were problems with the transfer.
notes.transfer
Imaging repeatedly stopped at 75%.
  • Enter Y in the removed field if the disk is removed from the collection.
removed
Y

Completing the imaging process

  • Put the media back in the collection’s box and move or remove the pink “To image” flag as necessary if you are working on a large collection.
  • Move the media to the “Small collections complete” box if you are working on a small collection without a box.

Metadata

Deprecated

  • Open Cygwin and enter the following commands:
  • Connect to ARCHV Mac.
    $ ssh archv
  • Change to the diskImages directory and change directory to the objects folder for the media object.
    $ diskimages
    $cd M1111/M1111-0004/objects
  • Run disktype on the disk image to get the file system metadata.
    $ disktype M1111-0004.E01
  • Copy the file system information data into the media objects CMS record.
  • Run program to move metadata files to metadata directory.
    $ movemetadata
