Capacity of an average drive is constantly growing, and selective imaging becomes a way out for many investigators, to keep their backlogs smaller.
We at Atola have developed selective imaging functionality to make it possible to image only sectors containing data.
The feature is supported in these file systems: NTFS, APFS, XFS, ext2/3/4, HFS, HFS+, ExFAT, FAT16, FAT32.
1) Click Change button to adjust imaging settings
2) In Passes tab, click on the value in What to image column
3) Select Sectors with data in the drop-down menu
4) Click Show button to preview the partitions on the source drive.
NB Imaging individual partitions is possible: just unselect the partitions you do not want to image. The imaging report will document this setting and indicate, which of the partitions have been imaged and the sector ranges in which the partitions were located.
5) Click Start button to proceed with imaging
You can see the partitions being imaged in the imaging log. In the imaging bar, the blue areas represent the sectors that are planned to be imaged. These are the sectors that belong to the drive's partitions and contain data.
